23 | 国外很多网站都在使用 Cloudflare CDN，但分配给中国内地访客的 IP 并不友好（延迟高、丢包多、速度慢）。
24 | 虽然 Cloudflare 公开了所有 [IP 段](https://www.cloudflare.com/ips/) ，但想要在这么多 IP 中找到适合自己的，怕是要累死，于是就有了这个软件。

36 | ## \# 快速使用
37 |
38 | ### 下载运行
39 |
40 | 1. 下载编译好的可执行文件
41 | 2. 双击运行 `CloudflareST.exe` 文件（Windows 系统），等待测速完成...
42 |
43 |
44 | 「 点击查看 Linux 系统下的使用示例 」
45 |
46 | ****
47 |
48 | 以下命令仅为示例，版本号和文件名请前往 [**Releases**](https:/ 查看。
49 |
50 | ``` yaml
51 | # 如果是第一次使用，则建议创建新文件夹（后续更新时，跳过该步骤）
52 | mkdir CloudflareST
53 |
54 | # 进入文件夹（后续更新，只需要从这里重复下面的下载、解压命令即可）
55 | cd CloudflareST
56 |
57 | # 下载 CloudflareST 压缩包（自行根据需求替换 URL 中 [版本号] 和 [文件名]）
58 | wget -N https://github.com/XIU2/CloudflareSpeedTest/releases/download/v2.2.2/CloudflareST_linux_amd64.tar.gz
59 | # 如果你是在国内服务器上下载，那么请使用下面这几个镜像加速：
60 | # wget -N https://download.fastgit.org/XIU2/CloudflareSpeedTest/releases/download/v2.2.2/CloudflareST_linux_amd64.tar.gz
61 | # wget -N https://ghproxy.com/https://github.com/XIU2/CloudflareSpeedTest/releases/download/v2.2.2/CloudflareST_linux_amd64.tar.gz
62 | # 如果下载失败的话，尝试删除 -N 参数（如果是为了更新，则记得提前删除旧压缩包 rm CloudflareST_linux_amd64.tar.gz ）
63 |
64 | # 解压（不需要删除旧文件，会直接覆盖，自行根据需求替换 文件名）
65 | tar -zxf CloudflareST_linux_amd64.tar.gz
66 |
67 | # 赋予执行权限
68 | chmod +x CloudflareST
69 |
70 | # 运行（不带参数）
71 | ./CloudflareST
72 |
73 | # 运行（带参数示例）
74 | ./CloudflareST -dd -tll 90
75 | ```
76 |
77 | > 如果平**均延迟非常低**（如 0.xx），则说明 CloudflareST **测速时走了代理**，请先关闭代理软件后再测速。
78 | > 如果在**路由器**上运行，建议先关闭路由器内的代理（或将其排除），否则测速结果可能会**不准确/无法使用**。

85 |
86 | ### 结果示例
87 |
88 | 测速完毕后，默认会显示**最快的 10 个 IP**，示例：
89 |
90 | ``` bash
91 | IP 地址 已发送 已接收 丢包率 平均延迟 下载速度 (MB/s)
92 | 104.27.200.69 4 4 0.00 146.23 28.64
93 | 172.67.60.78 4 4 0.00 139.82 15.02
94 | 104.25.140.153 4 4 0.00 146.49 14.90
95 | 104.27.192.65 4 4 0.00 140.28 14.07
96 | 172.67.62.214 4 4 0.00 139.29 12.71
97 | 104.27.207.5 4 4 0.00 145.92 11.95
98 | 172.67.54.193 4 4 0.00 146.71 11.55
99 | 104.22.66.8 4 4 0.00 147.42 11.11
100 | 104.27.197.63 4 4 0.00 131.29 10.26
101 | 172.67.58.91 4 4 0.00 140.19 9.14
102 | ...
103 |
104 | # 如果平均延迟非常低（如 0.xx），则说明 CloudflareST 测速时走了代理，请先关闭代理软件后再测速。
105 | # 如果在路由器上运行，请先关闭路由器内的代理（或将其排除），否则测速结果可能会不准确/无法使用。
106 |
107 | # 因为每次测速都是在每个 IP 段中随机 IP，所以每次的测速结果都不可能相同，这是正常的！
108 |
109 | # 注意！我发现电脑开机后第一次测速延迟会明显偏高（手动 TCPing 也一样），后续测速都正常
110 | # 因此建议大家开机后第一次正式测速前，先随便测几个 IP（无需等待延迟测速完成，只要进度条动了就可以直接关了）
111 |
112 | # 软件在 默认参数 下的整个流程大概步骤：
113 | # 1. 延迟测速（默认 TCPing 模式，HTTPing 模式需要手动加上参数）
114 | # 2. 延迟排序（延迟从低到高排序，不同丢包率的会分开独立排序，因此可能会有一些延迟低但丢包的 IP 被排到后面）
115 | # 3. 下载测速（从延迟最低的 IP 开始依次下载测速，默认测够 10 个就会停止）
116 | # 4. 速度排序（速度从高到低排序）
117 | # 5. 输出结果（可依靠参数控制是否输出到命令行(-p 0)/文件(-o "")）
118 | ```
119 |
120 | 测速结果第一行就是**既下载速度最快、又平均延迟最低的最快 IP**！至于拿来干嘛？取决于你~
121 |
122 | 完整结果保存在当前目录下的 `result.csv` 文件中，用**记事本/表格软件**打开，格式如下：
123 |
124 | ```
125 | IP 地址, 已发送, 已接收, 丢包率, 平均延迟, 下载速度 (MB/s)
126 | 104.27.200.69,4,4,0.00,146.23,28.64
127 | ```
128 |
129 | > _大家可以按自己需求，对完整结果**进一步筛选处理**，或者去看一看进阶使用**指定过滤条件**！_
130 |
131 | ****
132 | ## \# 进阶使用
133 |
134 | 直接运行使用的是默认参数，如果想要测速结果更全面、更符合自己的要求，可以自定义参数。
135 |
136 | ``` cmd
137 | C:\>CloudflareST.exe -h
138 |
139 | CloudflareSpeedTest vX.X.X
140 | 测试 Cloudflare CDN 所有 IP 的延迟和速度，获取最快 IP (IPv4+IPv6)！
141 | https://github.com/XIU2/CloudflareSpeedTest
142 |
143 | 参数：
144 | -n 200
145 | 延迟测速线程；越多延迟测速越快，性能弱的设备 (如路由器) 请勿太高；(默认 200 最多 1000)
146 | -t 4
147 | 延迟测速次数；单个 IP 延迟测速次数，为 1 时将过滤丢包的IP；(默认 4 次)
148 | -dn 10
149 | 下载测速数量；延迟测速并排序后，从最低延迟起下载测速的数量；(默认 10 个)
150 | -dt 10
151 | 下载测速时间；单个 IP 下载测速最长时间，不能太短；(默认 10 秒)
152 | -tp 443
153 | 指定测速端口；延迟测速/下载测速时使用的端口；(默认 443 端口)
154 | -url https://cf.xiu2.xyz/url
155 | 指定测速地址；延迟测速(HTTPing)/下载测速时使用的地址，默认地址不保证可用性，建议自建；
156 |
157 | -httping
158 | 切换测速模式；延迟测速模式改为 HTTP 协议，所用测试地址为 [-url] 参数；(默认 TCPing)
159 | 注意：HTTPing 本质上也算一种 网络扫描 行为，因此如果你在服务器上面运行，需要降低并发(-n)，否则可能会被一些严格的商家暂停服务。
160 | 如果你遇到 HTTPing 首次测速可用 IP 数量正常，后续测速越来越少甚至直接为 0，但停一段时间后又恢复了的情况，那么也可能是被 运营商、Cloudflare CDN 认为你在网络扫描而 触发临时限制机制，因此才会过一会儿就恢复了，建议降低并发(-n)减少这种情况的发生。
161 | -httping-code 200
162 | 有效状态代码；HTTPing 延迟测速时网页返回的有效 HTTP 状态码，仅限一个；(默认 200 301 302)
163 | -cfcolo HKG,KHH,NRT,LAX,SEA,SJC,FRA,MAD
164 | 匹配指定地区；地区名为当地机场三字码，英文逗号分隔，仅 HTTPing 模式可用；(默认 所有地区)
165 |
166 | -tl 200
167 | 平均延迟上限；只输出低于指定平均延迟的 IP，可与其他上限/下限搭配；(默认 9999 ms)
168 | -tll 40
169 | 平均延迟下限；只输出高于指定平均延迟的 IP，可与其他上限/下限搭配；(默认 0 ms)
170 | -sl 5
171 | 下载速度下限；只输出高于指定下载速度的 IP，凑够指定数量 [-dn] 才会停止测速；(默认 0.00 MB/s)
172 |
173 | -p 10
174 | 显示结果数量；测速后直接显示指定数量的结果，为 0 时不显示结果直接退出；(默认 10 个)
175 | -f ip.txt
176 | IP段数据文件；如路径含有空格请加上引号；支持其他 CDN IP段；(默认 ip.txt)
177 | -ip 1.1.1.1,2.2.2.2/24,2606:4700::/32
178 | 指定IP段数据；直接通过参数指定要测速的 IP 段数据，英文逗号分隔；(默认 空)
179 | -o result.csv
180 | 写入结果文件；如路径含有空格请加上引号；值为空时不写入文件 [-o ""]；(默认 result.csv)
181 |
182 | -dd
183 | 禁用下载测速；禁用后测速结果会按延迟排序 (默认按下载速度排序)；(默认 启用)
184 | -allip
185 | 测速全部的IP；对 IP 段中的每个 IP (仅支持 IPv4) 进行测速；(默认 每个 /24 段随机测速一个 IP)
186 |
187 | -v
188 | 打印程序版本 + 检查版本更新
189 | -h
190 | 打印帮助说明
191 | ```
192 |
193 | ### 使用示例
194 |
195 | Windows 要指定参数需要在 CMD 中运行，或者把参数添加到快捷方式目标中。
196 |
197 | > **注意**：各参数均有**默认值**，使用默认值的参数是可以省略的（**按需选择**），参数**不分前后顺序**。
198 | > **提示**：Windows **PowerShell** 只需把下面命令中的 `CloudflareST.exe` 改为 `.\CloudflareST.exe` 即可。
199 | > **提示**：Linux 系统只需要把下面命令中的 `CloudflareST.exe` 改为 `./CloudflareST` 即可。

212 | 很多人打开 CMD 以**绝对路径**运行 CloudflareST 会报错，这是因为默认的 `-f ip.txt` 参数是相对路径，需要指定绝对路径的 ip.txt 才行，但这样毕竟太麻烦了，因此还是建议进入 CloudflareST 程序目录下，以**相对路径**方式运行：
213 |
214 | **方式 一**：
215 | 1. 打开 CloudflareST 程序所在目录
216 | 2. 空白处按下 Shift + 鼠标右键 显示右键菜单
217 | 3. 选择 **\[在此处打开命令窗口\]** 来打开 CMD 窗口，此时默认就位于当前目录下
218 | 4. 输入带参数的命令，如：`CloudflareST.exe -tll 50 -tl 200`即可运行
219 |
220 | **方式 二**：
221 | 1. 打开 CloudflareST 程序所在目录
222 | 2. 直接在文件夹地址栏中全选并输入 `cmd` 回车来打开 CMD 窗口，此时默认就位于当前目录下
223 | 4. 输入带参数的命令，如：`CloudflareST.exe -tll 50 -tl 200`即可运行
224 |
225 | > 当然你也可以随便打开一个 CMD 窗口，然后输入如 `cd /d "D:\Program Files\CloudflareST"` 来进入程序目录
226 |
227 | > **提示**：如果用的是 **PowerShell** 只需把命令中的 `CloudflareST.exe` 改为 `.\CloudflareST.exe` 即可。

289 | 目前有两种延迟测速模式，分别为 **TCP 协议、HTTP 协议**。
290 | TCP 协议耗时更短、消耗资源更少，超时时间为 1 秒，该协议为默认模式。
291 | HTTP 协议适用于快速测试某域名指向某 IP 时是否可以访问，超时时间为 2 秒。
292 | 同一个 IP，各协议去 Ping 得到的延迟一般为：**ICMP < TCP < HTTP**，越靠右对丢包等网络波动越敏感。
293 |
294 | > 注意：HTTPing 本质上也算一种**网络扫描**行为，因此如果你在服务器上面运行，需要**降低并发**(`-n`)，否则可能会被一些严格的商家暂停服务。如果你遇到 HTTPing 首次测速可用 IP 数量正常，后续测速越来越少甚至直接为 0，但停一段时间后又恢复了的情况，那么也可能是被 运营商、Cloudflare CDN 认为你在网络扫描而**触发临时限制机制**，因此才会过一会儿就恢复了，建议**降低并发**(`-n`)减少这种情况的发生。

85 | 104.27.197.63 4 4 0.00 131.29 10.26
86 | 172.67.58.91 4 4 0.00 140.19 9.14
87 | ...
88 |
89 | # 如果平均延迟非常低（如 0.xx），则说明 CloudflareST 测速时走了代理，请先关闭代理软件后再测速。
90 | # 如果在路由器上运行，请先关闭路由器内的代理（或将其排除），否则测速结果可能会不准确/无法使用。
91 |
92 | # 因为每次测速都是在每个 IP 段中随机 IP，所以每次的测速结果都不可能相同，这是正常的！
93 |
94 | # 注意！我发现电脑开机后第一次测速延迟会明显偏高（手动 TCPing 也一样），后续测速都正常
95 | # 因此建议大家开机后第一次正式测速前，先随便测几个 IP（无需等待延迟测速完成，只要进度条动了就可以直接关了）
96 |
97 | # 软件在 默认参数 下的整个流程大概步骤：
98 | # 1. 延迟测速（默认 TCPing 模式，HTTPing 模式需要手动加上参数）
99 | # 2. 延迟排序（延迟从低到高排序，不同丢包率的会分开独立排序，因此可能会有一些延迟低但丢包的 IP 被排到后面）
100 | # 3. 下载测速（从延迟最低的 IP 开始依次下载测速，默认测够 10 个就会停止）
101 | # 4. 速度排序（速度从高到低排序）
102 | # 5. 输出结果（可依靠参数控制是否输出到命令行(-p 0)/文件(-o "")）
103 | ```
104 |
105 | 测速结果第一行就是**既下载速度最快、又平均延迟最低的最快 IP**！至于拿来干嘛？取决于你~
106 |
107 | 完整结果保存在当前目录下的 `result.csv` 文件中，用**记事本/表格软件**打开，格式如下：
108 |
109 | ```
110 | IP 地址, 已发送, 已接收, 丢包率, 平均延迟, 下载速度 (MB/s)
111 | 104.27.200.69,4,4,0.00,146.23,28.64
112 | ```

134 | 下载测速数量；延迟测速并排序后，从最低延迟起下载测速的数量；(默认 10 个)
135 | -dt 10
136 | 下载测速时间；单个 IP 下载测速最长时间，不能太短；(默认 10 秒)
137 | -tp 443
138 | 指定测速端口；延迟测速/下载测速时使用的端口；(默认 443 端口)
139 | -url https://cf.xiu2.xyz/url
140 | 指定测速地址；延迟测速(HTTPing)/下载测速时使用的地址，默认地址不保证可用性，建议自建；
141 |
142 | -httping
143 | 切换测速模式；延迟测速模式改为 HTTP 协议，所用测试地址为 [-url] 参数；(默认 TCPing)
144 | 注意：HTTPing 本质上也算一种 网络扫描 行为，因此如果你在服务器上面运行，需要降低并发(-n)，否则可能会被一些严格的商家暂停服务。
145 | 如果你遇到 HTTPing 首次测速可用 IP 数量正常，后续测速越来越少甚至直接为 0，但停一段时间后又恢复了的情况，那么也可能是被 运营商、Cloudflare CDN 认为你在网络扫描而 触发临时限制机制，因此才会过一会儿就恢复了，建议降低并发(-n)减少这种情况的发生。
146 | -httping-code 200
147 | 有效状态代码；HTTPing 延迟测速时网页返回的有效 HTTP 状态码，仅限一个；(默认 200 301 302)
148 | -cfcolo HKG,KHH,NRT,LAX,SEA,SJC,FRA,MAD
149 | 匹配指定地区；地区名为当地机场三字码，英文逗号分隔，仅 HTTPing 模式可用；(默认 所有地区)
150 |
151 | -tl 200

180 | Windows 要指定参数需要在 CMD 中运行，或者把参数添加到快捷方式目标中。
181 |
182 | > **注意**：各参数均有**默认值**，使用默认值的参数是可以省略的（**按需选择**），参数**不分前后顺序**。
183 | > **提示**：Windows **PowerShell** 只需把下面命令中的 `CloudflareST.exe` 改为 `.\CloudflareST.exe` 即可。
184 | > **提示**：Linux 系统只需要把下面命令中的 `CloudflareST.exe` 改为 `./CloudflareST` 即可。

197 | 很多人打开 CMD 以**绝对路径**运行 CloudflareST 会报错，这是因为默认的 `-f ip.txt` 参数是相对路径，需要指定绝对路径的 ip.txt 才行，但这样毕竟太麻烦了，因此还是建议进入 CloudflareST 程序目录下，以**相对路径**方式运行：
198 |
199 | **方式 一**：
200 | 1. 打开 CloudflareST 程序所在目录
201 | 2. 空白处按下 Shift + 鼠标右键 显示右键菜单
202 | 3. 选择 **\[在此处打开命令窗口\]** 来打开 CMD 窗口，此时默认就位于当前目录下
203 | 4. 输入带参数的命令，如：`CloudflareST.exe -tll 50 -tl 200`即可运行
204 |
205 | **方式 二**：
206 | 1. 打开 CloudflareST 程序所在目录
207 | 2. 直接在文件夹地址栏中全选并输入 `cmd` 回车来打开 CMD 窗口，此时默认就位于当前目录下
208 | 4. 输入带参数的命令，如：`CloudflareST.exe -tll 50 -tl 200`即可运行
209 |
210 | > 当然你也可以随便打开一个 CMD 窗口，然后输入如 `cd /d "D:\Program Files\CloudflareST"` 来进入程序目录
211 |

273 |
274 | 目前有两种延迟测速模式，分别为 **TCP 协议、HTTP 协议**。
275 | TCP 协议耗时更短、消耗资源更少，超时时间为 1 秒，该协议为默认模式。
276 | HTTP 协议适用于快速测试某域名指向某 IP 时是否可以访问，超时时间为 2 秒。
277 | 同一个 IP，各协议去 Ping 得到的延迟一般为：**ICMP < TCP < HTTP**，越靠右对丢包等网络波动越敏感。
278 |
279 | > 注意：HTTPing 本质上也算一种**网络扫描**行为，因此如果你在服务器上面运行，需要**降低并发**(`-n`)，否则可能会被一些严格的商家暂停服务。如果你遇到 HTTPing 首次测速可用 IP 数量正常，后续测速越来越少甚至直接为 0，但停一段时间后又恢复了的情况，那么也可能是被 运营商、Cloudflare CDN 认为你在网络扫描而**触发临时限制机制**，因此才会过一会儿就恢复了，建议**降低并发**(`-n`)减少这种情况的发生。
280 |
281 | ``` bash
282 | # 只需加上 -httping 参数即可切换到 HTTP 协议延迟测速模式
283 | CloudflareST.exe -httping
284 |
285 | # 软件会根据访问时网页返回的有效 HTTP 状态码来判断可用性（当然超时也算），默认对返回 200 301 302 这三个 HTTP 状态码的视为有效，可以手动指定认为有效的 HTTP 状态码，但只能指定一个（你需要提前确定测试地址正常情况下会返回哪个状态码）

600 | ```bash
601 | go build -ldflags "-s -w -X main.version=v2.3.3"
602 | # 在 CloudflareSpeedTest 目录中通过命令行（例如 CMD、Bat 脚本）运行该命令，即可编译一个可在和当前设备同样系统、位数、架构的环境下运行的二进制程序（Go 会自动检测你的系统位数、架构）且版本号为 v2.3.3
603 | ```
604 |
605 | 如果想要在 Windows 64位系统下编译**其他系统、架构、位数**，那么需要指定 **GOOS** 和 **GOARCH** 变量。
606 |
607 | 例如在 Windows 系统下编译一个适用于 **Linux 系统 amd 架构 64 位**的二进制程序：
608 |
609 | ```bat
610 | SET GOOS=linux
611 | SET GOARCH=amd64
612 | go build -ldflags "-s -w -X main.version=v2.3.3"
613 | ```
614 |
615 | 例如在 Linux 系统下编译一个适用于 **Windows 系统 amd 架构 32 位**的二进制程序：
616 |
617 | ```bash
618 | GOOS=windows
619 | GOARCH=386
620 | go build -ldflags "-s -w -X main.version=v2.3.3"
621 | ```
622 |
623 | > 可以运行 `go tool dist list` 来查看当前 Go 版本支持编译哪些组合。
624 |
625 | ****
626 |
627 | 当然，为了方便批量编译，我会专门指定一个变量为版本号，后续编译直接调用该版本号变量即可。
628 | 同时，批量编译的话，还需要分开放到不同文件夹才行（或者文件名不同），需要加上 `-o` 参数指定。
629 |
630 | ```bat
631 | :: Windows 系统下是这样：
632 | SET version=v2.3.3
633 | SET GOOS=linux
634 | SET GOARCH=amd64
635 | go build -o Releases\CloudflareST_linux_amd64\CloudflareST -ldflags "-s -w -X main.version=%version%"
636 | ```
637 |
638 | ```bash
639 | # Linux 系统下是这样：
640 | version=v2.3.3
641 | GOOS=windows
642 | GOARCH=386
643 | go build -o Releases/CloudflareST_windows_386/CloudflareST.exe -ldflags "-s -w -X main.version=${version}"
644 | ```
645 |
646 |

651 |
652 | The GPL-3.0 License.
--------------------------------------------------------------------------------
/LICENSE:
--------------------------------------------------------------------------------
1 | GNU GENERAL PUBLIC LICENSE
2 | Version 3, 29 June 2007
3 |
4 | Copyright (C) 2007 Free Software Foundation, Inc.
5 | Everyone is permitted to copy and distribute verbatim copies
6 | of this license document, but changing it is not allowed.
7 |
8 | Preamble
9 |
10 | The GNU General Public License is a free, copyleft license for
11 | software and other kinds of works.
12 |
13 | The licenses for most software and other practical works are designed
14 | to take away your freedom to share and change the works. By contrast,
15 | the GNU General Public License is intended to guarantee your freedom to
16 | share and change all versions of a program--to make sure it remains free
17 | software for all its users. We, the Free Software Foundation, use the
18 | GNU General Public License for most of our software; it applies also to
19 | any other work released this way by its authors. You can apply it to
20 | your programs, too.
21 |
22 | When we speak of free software, we are referring to freedom, not
23 | price. Our General Public Licenses are designed to make sure that you
24 | have the freedom to distribute copies of free software (and charge for
25 | them if you wish), that you receive source code or can get it if you
26 | want it, that you can change the software or use pieces of it in new
27 | free programs, and that you know you can do these things.
28 |
29 | To protect your rights, we need to prevent others from denying you
30 | these rights or asking you to surrender the rights. Therefore, you have
31 | certain responsibilities if you distribute copies of the software, or if
32 | you modify it: responsibilities to respect the freedom of others.
33 |
34 | For example, if you distribute copies of such a program, whether
35 | gratis or for a fee, you must pass on to the recipients the same
36 | freedoms that you received. You must make sure that they, too, receive
37 | or can get the source code. And you must show them these terms so they
38 | know their rights.
39 |
40 | Developers that use the GNU GPL protect your rights with two steps:
41 | (1) assert copyright on the software, and (2) offer you this License
42 | giving you legal permission to copy, distribute and/or modify it.
43 |
44 | For the developers' and authors' protection, the GPL clearly explains
45 | that there is no warranty for this free software. For both users' and
46 | authors' sake, the GPL requires that modified versions be marked as
47 | changed, so that their problems will not be attributed erroneously to
48 | authors of previous versions.
49 |
50 | Some devices are designed to deny users access to install or run
51 | modified versions of the software inside them, although the manufacturer
52 | can do so. This is fundamentally incompatible with the aim of
53 | protecting users' freedom to change the software. The systematic
54 | pattern of such abuse occurs in the area of products for individuals to
55 | use, which is precisely where it is most unacceptable. Therefore, we
56 | have designed this version of the GPL to prohibit the practice for those
57 | products. If such problems arise substantially in other domains, we
58 | stand ready to extend this provision to those domains in future versions
59 | of the GPL, as needed to protect the freedom of users.
60 |
61 | Finally, every program is threatened constantly by software patents.
62 | States should not allow patents to restrict development and use of
63 | software on general-purpose computers, but in those that do, we wish to
64 | avoid the special danger that patents applied to a free program could
65 | make it effectively proprietary. To prevent this, the GPL assures that
66 | patents cannot be used to render the program non-free.
67 |
68 | The precise terms and conditions for copying, distribution and
69 | modification follow.
70 |
71 | TERMS AND CONDITIONS
72 |
73 | 0. Definitions.
74 |
75 | "This License" refers to version 3 of the GNU General Public License.
76 |
77 | "Copyright" also means copyright-like laws that apply to other kinds of
78 | works, such as semiconductor masks.
79 |
80 | "The Program" refers to any copyrightable work licensed under this
81 | License. Each licensee is addressed as "you". "Licensees" and
82 | "recipients" may be individuals or organizations.
83 |
84 | To "modify" a work means to copy from or adapt all or part of the work
85 | in a fashion requiring copyright permission, other than the making of an
86 | exact copy. The resulting work is called a "modified version" of the
87 | earlier work or a work "based on" the earlier work.
88 |
89 | A "covered work" means either the unmodified Program or a work based
90 | on the Program.
91 |
92 | To "propagate" a work means to do anything with it that, without
93 | permission, would make you directly or secondarily liable for
94 | infringement under applicable copyright law, except executing it on a
95 | computer or modifying a private copy. Propagation includes copying,
96 | distribution (with or without modification), making available to the
97 | public, and in some countries other activities as well.
98 |
99 | To "convey" a work means any kind of propagation that enables other
100 | parties to make or receive copies. Mere interaction with a user through
101 | a computer network, with no transfer of a copy, is not conveying.
102 |
103 | An interactive user interface displays "Appropriate Legal Notices"
104 | to the extent that it includes a convenient and prominently visible
105 | feature that (1) displays an appropriate copyright notice, and (2)
106 | tells the user that there is no warranty for the work (except to the
107 | extent that warranties are provided), that licensees may convey the
108 | work under this License, and how to view a copy of this License. If
109 | the interface presents a list of user commands or options, such as a
110 | menu, a prominent item in the list meets this criterion.
111 |
112 | 1. Source Code.
113 |
114 | The "source code" for a work means the preferred form of the work
115 | for making modifications to it. "Object code" means any non-source
116 | form of a work.
117 |
118 | A "Standard Interface" means an interface that either is an official
119 | standard defined by a recognized standards body, or, in the case of
120 | interfaces specified for a particular programming language, one that
121 | is widely used among developers working in that language.
122 |
123 | The "System Libraries" of an executable work include anything, other
124 | than the work as a whole, that (a) is included in the normal form of
125 | packaging a Major Component, but which is not part of that Major
126 | Component, and (b) serves only to enable use of the work with that
127 | Major Component, or to implement a Standard Interface for which an
128 | implementation is available to the public in source code form. A
129 | "Major Component", in this context, means a major essential component
130 | (kernel, window system, and so on) of the specific operating system
131 | (if any) on which the executable work runs, or a compiler used to
132 | produce the work, or an object code interpreter used to run it.
133 |
134 | The "Corresponding Source" for a work in object code form means all
135 | the source code needed to generate, install, and (for an executable
136 | work) run the object code and to modify the work, including scripts to
137 | control those activities. However, it does not include the work's
138 | System Libraries, or general-purpose tools or generally available free
139 | programs which are used unmodified in performing those activities but
140 | which are not part of the work. For example, Corresponding Source
141 | includes interface definition files associated with source files for
142 | the work, and the source code for shared libraries and dynamically
143 | linked subprograms that the work is specifically designed to require,
144 | such as by intimate data communication or control flow between those
145 | subprograms and other parts of the work.
146 |
147 | The Corresponding Source need not include anything that users
148 | can regenerate automatically from other parts of the Corresponding
149 | Source.
150 |
151 | The Corresponding Source for a work in source code form is that
152 | same work.
153 |
154 | 2. Basic Permissions.
155 |
156 | All rights granted under this License are granted for the term of
157 | copyright on the Program, and are irrevocable provided the stated
158 | conditions are met. This License explicitly affirms your unlimited
159 | permission to run the unmodified Program. The output from running a
160 | covered work is covered by this License only if the output, given its
161 | content, constitutes a covered work. This License acknowledges your
162 | rights of fair use or other equivalent, as provided by copyright law.
163 |
164 | You may make, run and propagate covered works that you do not
165 | convey, without conditions so long as your license otherwise remains
166 | in force. You may convey covered works to others for the sole purpose
167 | of having them make modifications exclusively for you, or provide you
168 | with facilities for running those works, provided that you comply with
169 | the terms of this License in conveying all material for which you do
170 | not control copyright. Those thus making or running the covered works
171 | for you must do so exclusively on your behalf, under your direction
172 | and control, on terms that prohibit them from making any copies of
173 | your copyrighted material outside their relationship with you.
174 |
175 | Conveying under any other circumstances is permitted solely under
176 | the conditions stated below. Sublicensing is not allowed; section 10
177 | makes it unnecessary.
178 |
179 | 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
180 |
181 | No covered work shall be deemed part of an effective technological
182 | measure under any applicable law fulfilling obligations under article
183 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or
184 | similar laws prohibiting or restricting circumvention of such
185 | measures.
186 |
187 | When you convey a covered work, you waive any legal power to forbid
188 | circumvention of technological measures to the extent such circumvention
189 | is effected by exercising rights under this License with respect to
190 | the covered work, and you disclaim any intention to limit operation or
191 | modification of the work as a means of enforcing, against the work's
192 | users, your or third parties' legal rights to forbid circumvention of
193 | technological measures.
194 |
195 | 4. Conveying Verbatim Copies.
196 |
197 | You may convey verbatim copies of the Program's source code as you
198 | receive it, in any medium, provided that you conspicuously and
199 | appropriately publish on each copy an appropriate copyright notice;
200 | keep intact all notices stating that this License and any
201 | non-permissive terms added in accord with section 7 apply to the code;
202 | keep intact all notices of the absence of any warranty; and give all
203 | recipients a copy of this License along with the Program.
204 |
205 | You may charge any price or no price for each copy that you convey,
206 | and you may offer support or warranty protection for a fee.
207 |
208 | 5. Conveying Modified Source Versions.
209 |
210 | You may convey a work based on the Program, or the modifications to
211 | produce it from the Program, in the form of source code under the
212 | terms of section 4, provided that you also meet all of these conditions:
213 |
214 | a) The work must carry prominent notices stating that you modified
215 | it, and giving a relevant date.
216 |
217 | b) The work must carry prominent notices stating that it is
218 | released under this License and any conditions added under section
219 | 7. This requirement modifies the requirement in section 4 to
220 | "keep intact all notices".
221 |
222 | c) You must license the entire work, as a whole, under this
223 | License to anyone who comes into possession of a copy. This
224 | License will therefore apply, along with any applicable section 7
225 | additional terms, to the whole of the work, and all its parts,
226 | regardless of how they are packaged. This License gives no
227 | permission to license the work in any other way, but it does not
228 | invalidate such permission if you have separately received it.
229 |
230 | d) If the work has interactive user interfaces, each must display
231 | Appropriate Legal Notices; however, if the Program has interactive
232 | interfaces that do not display Appropriate Legal Notices, your
233 | work need not make them do so.
234 |
235 | A compilation of a covered work with other separate and independent
236 | works, which are not by their nature extensions of the covered work,
237 | and which are not combined with it such as to form a larger program,
238 | in or on a volume of a storage or distribution medium, is called an
239 | "aggregate" if the compilation and its resulting copyright are not
240 | used to limit the access or legal rights of the compilation's users
241 | beyond what the individual works permit. Inclusion of a covered work
242 | in an aggregate does not cause this License to apply to the other
243 | parts of the aggregate.
244 |
245 | 6. Conveying Non-Source Forms.
246 |
247 | You may convey a covered work in object code form under the terms
248 | of sections 4 and 5, provided that you also convey the
249 | machine-readable Corresponding Source under the terms of this License,
250 | in one of these ways:
251 |
252 | a) Convey the object code in, or embodied in, a physical product
253 | (including a physical distribution medium), accompanied by the
254 | Corresponding Source fixed on a durable physical medium
255 | customarily used for software interchange.
256 |
257 | b) Convey the object code in, or embodied in, a physical product
258 | (including a physical distribution medium), accompanied by a
259 | written offer, valid for at least three years and valid for as
260 | long as you offer spare parts or customer support for that product
261 | model, to give anyone who possesses the object code either (1) a
262 | copy of the Corresponding Source for all the software in the
263 | product that is covered by this License, on a durable physical
264 | medium customarily used for software interchange, for a price no
265 | more than your reasonable cost of physically performing this
266 | conveying of source, or (2) access to copy the
267 | Corresponding Source from a network server at no charge.
268 |
269 | c) Convey individual copies of the object code with a copy of the
270 | written offer to provide the Corresponding Source. This
271 | alternative is allowed only occasionally and noncommercially, and
272 | only if you received the object code with such an offer, in accord
273 | with subsection 6b.
274 |
275 | d) Convey the object code by offering access from a designated
276 | place (gratis or for a charge), and offer equivalent access to the
277 | Corresponding Source in the same way through the same place at no
278 | further charge. You need not require recipients to copy the
279 | Corresponding Source along with the object code. If the place to
280 | copy the object code is a network server, the Corresponding Source
281 | may be on a different server (operated by you or a third party)
282 | that supports equivalent copying facilities, provided you maintain
283 | clear directions next to the object code saying where to find the
284 | Corresponding Source. Regardless of what server hosts the
285 | Corresponding Source, you remain obligated to ensure that it is
286 | available for as long as needed to satisfy these requirements.
287 |
288 | e) Convey the object code using peer-to-peer transmission, provided
289 | you inform other peers where the object code and Corresponding
290 | Source of the work are being offered to the general public at no
291 | charge under subsection 6d.
292 |
293 | A separable portion of the object code, whose source code is excluded
294 | from the Corresponding Source as a System Library, need not be
295 | included in conveying the object code work.
296 |
297 | A "User Product" is either (1) a "consumer product", which means any
298 | tangible personal property which is normally used for personal, family,
299 | or household purposes, or (2) anything designed or sold for incorporation
300 | into a dwelling. In determining whether a product is a consumer product,
301 | doubtful cases shall be resolved in favor of coverage. For a particular
302 | product received by a particular user, "normally used" refers to a
303 | typical or common use of that class of product, regardless of the status
304 | of the particular user or of the way in which the particular user
305 | actually uses, or expects or is expected to use, the product. A product
306 | is a consumer product regardless of whether the product has substantial
307 | commercial, industrial or non-consumer uses, unless such uses represent
308 | the only significant mode of use of the product.
309 |
310 | "Installation Information" for a User Product means any methods,
311 | procedures, authorization keys, or other information required to install
312 | and execute modified versions of a covered work in that User Product from
313 | a modified version of its Corresponding Source. The information must
314 | suffice to ensure that the continued functioning of the modified object
315 | code is in no case prevented or interfered with solely because
316 | modification has been made.
317 |
318 | If you convey an object code work under this section in, or with, or
319 | specifically for use in, a User Product, and the conveying occurs as
320 | part of a transaction in which the right of possession and use of the
321 | User Product is transferred to the recipient in perpetuity or for a
322 | fixed term (regardless of how the transaction is characterized), the
323 | Corresponding Source conveyed under this section must be accompanied
324 | by the Installation Information. But this requirement does not apply
325 | if neither you nor any third party retains the ability to install
326 | modified object code on the User Product (for example, the work has
327 | been installed in ROM).
328 |
329 | The requirement to provide Installation Information does not include a
330 | requirement to continue to provide support service, warranty, or updates
331 | for a work that has been modified or installed by the recipient, or for
332 | the User Product in which it has been modified or installed. Access to a
333 | network may be denied when the modification itself materially and
334 | adversely affects the operation of the network or violates the rules and
335 | protocols for communication across the network.
336 |
337 | Corresponding Source conveyed, and Installation Information provided,
338 | in accord with this section must be in a format that is publicly
339 | documented (and with an implementation available to the public in
340 | source code form), and must require no special password or key for
341 | unpacking, reading or copying.
342 |
343 | 7. Additional Terms.
344 |
345 | "Additional permissions" are terms that supplement the terms of this
346 | License by making exceptions from one or more of its conditions.
347 | Additional permissions that are applicable to the entire Program shall
348 | be treated as though they were included in this License, to the extent
349 | that they are valid under applicable law. If additional permissions
350 | apply only to part of the Program, that part may be used separately
351 | under those permissions, but the entire Program remains governed by
352 | this License without regard to the additional permissions.
353 |
354 | When you convey a copy of a covered work, you may at your option
355 | remove any additional permissions from that copy, or from any part of
356 | it. (Additional permissions may be written to require their own
357 | removal in certain cases when you modify the work.) You may place
358 | additional permissions on material, added by you to a covered work,
359 | for which you have or can give appropriate copyright permission.
360 |
361 | Notwithstanding any other provision of this License, for material you
362 | add to a covered work, you may (if authorized by the copyright holders of
363 | that material) supplement the terms of this License with terms:
364 |
365 | a) Disclaiming warranty or limiting liability differently from the
366 | terms of sections 15 and 16 of this License; or
367 |
368 | b) Requiring preservation of specified reasonable legal notices or
369 | author attributions in that material or in the Appropriate Legal
370 | Notices displayed by works containing it; or
371 |
372 | c) Prohibiting misrepresentation of the origin of that material, or
373 | requiring that modified versions of such material be marked in
374 | reasonable ways as different from the original version; or
375 |
376 | d) Limiting the use for publicity purposes of names of licensors or
377 | authors of the material; or
378 |
379 | e) Declining to grant rights under trademark law for use of some
380 | trade names, trademarks, or service marks; or
381 |
382 | f) Requiring indemnification of licensors and authors of that
383 | material by anyone who conveys the material (or modified versions of
384 | it) with contractual assumptions of liability to the recipient, for
385 | any liability that these contractual assumptions directly impose on
386 | those licensors and authors.
387 |
388 | All other non-permissive additional terms are considered "further
389 | restrictions" within the meaning of section 10. If the Program as you
390 | received it, or any part of it, contains a notice stating that it is
391 | governed by this License along with a term that is a further
392 | restriction, you may remove that term. If a license document contains
393 | a further restriction but permits relicensing or conveying under this
394 | License, you may add to a covered work material governed by the terms
395 | of that license document, provided that the further restriction does
396 | not survive such relicensing or conveying.
397 |
398 | If you add terms to a covered work in accord with this section, you
399 | must place, in the relevant source files, a statement of the
400 | additional terms that apply to those files, or a notice indicating
401 | where to find the applicable terms.
402 |
403 | Additional terms, permissive or non-permissive, may be stated in the
404 | form of a separately written license, or stated as exceptions;
405 | the above requirements apply either way.
406 |
407 | 8. Termination.
408 |
409 | You may not propagate or modify a covered work except as expressly
410 | provided under this License. Any attempt otherwise to propagate or
411 | modify it is void, and will automatically terminate your rights under
412 | this License (including any patent licenses granted under the third
413 | paragraph of section 11).
414 |
415 | However, if you cease all violation of this License, then your
416 | license from a particular copyright holder is reinstated (a)
417 | provisionally, unless and until the copyright holder explicitly and
418 | finally terminates your license, and (b) permanently, if the copyright
419 | holder fails to notify you of the violation by some reasonable means
420 | prior to 60 days after the cessation.
421 |
422 | Moreover, your license from a particular copyright holder is
423 | reinstated permanently if the copyright holder notifies you of the
424 | violation by some reasonable means, this is the first time you have
425 | received notice of violation of this License (for any work) from that
426 | copyright holder, and you cure the violation prior to 30 days after
427 | your receipt of the notice.
428 |
429 | Termination of your rights under this section does not terminate the
430 | licenses of parties who have received copies or rights from you under
431 | this License. If your rights have been terminated and not permanently
432 | reinstated, you do not qualify to receive new licenses for the same
433 | material under section 10.
434 |
435 | 9. Acceptance Not Required for Having Copies.
436 |
437 | You are not required to accept this License in order to receive or
438 | run a copy of the Program. Ancillary propagation of a covered work
439 | occurring solely as a consequence of using peer-to-peer transmission
440 | to receive a copy likewise does not require acceptance. However,
441 | nothing other than this License grants you permission to propagate or
442 | modify any covered work. These actions infringe copyright if you do
443 | not accept this License. Therefore, by modifying or propagating a
444 | covered work, you indicate your acceptance of this License to do so.
445 |
446 | 10. Automatic Licensing of Downstream Recipients.
447 |
448 | Each time you convey a covered work, the recipient automatically
449 | receives a license from the original licensors, to run, modify and
450 | propagate that work, subject to this License. You are not responsible
451 | for enforcing compliance by third parties with this License.
452 |
453 | An "entity transaction" is a transaction transferring control of an
454 | organization, or substantially all assets of one, or subdividing an
455 | organization, or merging organizations. If propagation of a covered
456 | work results from an entity transaction, each party to that
457 | transaction who receives a copy of the work also receives whatever
458 | licenses to the work the party's predecessor in interest had or could
459 | give under the previous paragraph, plus a right to possession of the
460 | Corresponding Source of the work from the predecessor in interest, if
461 | the predecessor has it or can get it with reasonable efforts.
462 |
463 | You may not impose any further restrictions on the exercise of the
464 | rights granted or affirmed under this License. For example, you may
465 | not impose a license fee, royalty, or other charge for exercise of
466 | rights granted under this License, and you may not initiate litigation
467 | (including a cross-claim or counterclaim in a lawsuit) alleging that
468 | any patent claim is infringed by making, using, selling, offering for
469 | sale, or importing the Program or any portion of it.
470 |
471 | 11. Patents.
472 |
473 | A "contributor" is a copyright holder who authorizes use under this
474 | License of the Program or a work on which the Program is based. The
475 | work thus licensed is called the contributor's "contributor version".
476 |
477 | A contributor's "essential patent claims" are all patent claims
478 | owned or controlled by the contributor, whether already acquired or
479 | hereafter acquired, that would be infringed by some manner, permitted
480 | by this License, of making, using, or selling its contributor version,
481 | but do not include claims that would be infringed only as a
482 | consequence of further modification of the contributor version. For
483 | purposes of this definition, "control" includes the right to grant
484 | patent sublicenses in a manner consistent with the requirements of
485 | this License.
486 |
487 | Each contributor grants you a non-exclusive, worldwide, royalty-free
488 | patent license under the contributor's essential patent claims, to
489 | make, use, sell, offer for sale, import and otherwise run, modify and
490 | propagate the contents of its contributor version.
491 |
492 | In the following three paragraphs, a "patent license" is any express
493 | agreement or commitment, however denominated, not to enforce a patent
494 | (such as an express permission to practice a patent or covenant not to
495 | sue for patent infringement). To "grant" such a patent license to a
496 | party means to make such an agreement or commitment not to enforce a
497 | patent against the party.
498 |
499 | If you convey a covered work, knowingly relying on a patent license,
500 | and the Corresponding Source of the work is not available for anyone
501 | to copy, free of charge and under the terms of this License, through a
502 | publicly available network server or other readily accessible means,
503 | then you must either (1) cause the Corresponding Source to be so
504 | available, or (2) arrange to deprive yourself of the benefit of the
505 | patent license for this particular work, or (3) arrange, in a manner
506 | consistent with the requirements of this License, to extend the patent
507 | license to downstream recipients. "Knowingly relying" means you have
508 | actual knowledge that, but for the patent license, your conveying the
509 | covered work in a country, or your recipient's use of the covered work
510 | in a country, would infringe one or more identifiable patents in that
511 | country that you have reason to believe are valid.
512 |
513 | If, pursuant to or in connection with a single transaction or
514 | arrangement, you convey, or propagate by procuring conveyance of, a
515 | covered work, and grant a patent license to some of the parties
516 | receiving the covered work authorizing them to use, propagate, modify
517 | or convey a specific copy of the covered work, then the patent license
518 | you grant is automatically extended to all recipients of the covered
519 | work and works based on it.
520 |
521 | A patent license is "discriminatory" if it does not include within
522 | the scope of its coverage, prohibits the exercise of, or is
523 | conditioned on the non-exercise of one or more of the rights that are
524 | specifically granted under this License. You may not convey a covered
525 | work if you are a party to an arrangement with a third party that is
526 | in the business of distributing software, under which you make payment
527 | to the third party based on the extent of your activity of conveying
528 | the work, and under which the third party grants, to any of the
529 | parties who would receive the covered work from you, a discriminatory
530 | patent license (a) in connection with copies of the covered work
531 | conveyed by you (or copies made from those copies), or (b) primarily
532 | for and in connection with specific products or compilations that
533 | contain the covered work, unless you entered into that arrangement,
534 | or that patent license was granted, prior to 28 March 2007.
535 |
536 | Nothing in this License shall be construed as excluding or limiting
537 | any implied license or other defenses to infringement that may
538 | otherwise be available to you under applicable patent law.
539 |
540 | 12. No Surrender of Others' Freedom.
541 |
542 | If conditions are imposed on you (whether by court order, agreement or
543 | otherwise) that contradict the conditions of this License, they do not
544 | excuse you from the conditions of this License. If you cannot convey a
545 | covered work so as to satisfy simultaneously your obligations under this
546 | License and any other pertinent obligations, then as a consequence you may
547 | not convey it at all. For example, if you agree to terms that obligate you
548 | to collect a royalty for further conveying from those to whom you convey
549 | the Program, the only way you could satisfy both those terms and this
550 | License would be to refrain entirely from conveying the Program.
551 |
552 | 13. Use with the GNU Affero General Public License.
553 |
554 | Notwithstanding any other provision of this License, you have
555 | permission to link or combine any covered work with a work licensed
556 | under version 3 of the GNU Affero General Public License into a single
557 | combined work, and to convey the resulting work. The terms of this
558 | License will continue to apply to the part which is the covered work,
559 | but the special requirements of the GNU Affero General Public License,
560 | section 13, concerning interaction through a network will apply to the
561 | combination as such.
562 |
563 | 14. Revised Versions of this License.
564 |
565 | The Free Software Foundation may publish revised and/or new versions of
566 | the GNU General Public License from time to time. Such new versions will
567 | be similar in spirit to the present version, but may differ in detail to
568 | address new problems or concerns.
569 |
570 | Each version is given a distinguishing version number. If the
571 | Program specifies that a certain numbered version of the GNU General
572 | Public License "or any later version" applies to it, you have the
573 | option of following the terms and conditions either of that numbered
574 | version or of any later version published by the Free Software
575 | Foundation. If the Program does not specify a version number of the
576 | GNU General Public License, you may choose any version ever published
577 | by the Free Software Foundation.
578 |
579 | If the Program specifies that a proxy can decide which future
580 | versions of the GNU General Public License can be used, that proxy's
581 | public statement of acceptance of a version permanently authorizes you
582 | to choose that version for the Program.
583 |
584 | Later license versions may give you additional or different
585 | permissions. However, no additional obligations are imposed on any
586 | author or copyright holder as a result of your choosing to follow a
587 | later version.
588 |
589 | 15. Disclaimer of Warranty.
590 |
591 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
592 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
593 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
594 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
595 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
596 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
597 | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
598 | ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
599 |
600 | 16. Limitation of Liability.
601 |
602 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
603 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
604 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
605 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
606 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
607 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
608 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
609 | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
610 | SUCH DAMAGES.
611 |
612 | 17. Interpretation of Sections 15 and 16.
613 |
614 | If the disclaimer of warranty and limitation of liability provided
615 | above cannot be given local legal effect according to their terms,
616 | reviewing courts shall apply local law that most closely approximates
617 | an absolute waiver of all civil liability in connection with the
618 | Program, unless a warranty or assumption of liability accompanies a
619 | copy of the Program in return for a fee.
620 |
621 | END OF TERMS AND CONDITIONS
622 |
623 | How to Apply These Terms to Your New Programs
624 |
625 | If you develop a new program, and you want it to be of the greatest
626 | possible use to the public, the best way to achieve this is to make it
627 | free software which everyone can redistribute and change under these terms.
628 |
629 | To do so, attach the following notices to the program. It is safest
630 | to attach them to the start of each source file to most effectively
631 | state the exclusion of warranty; and each file should have at least
632 | the "copyright" line and a pointer to where the full notice is found.
633 |
634 |
635 | Copyright (C)
636 |
637 | This program is free software: you can redistribute it and/or modify
638 | it under the terms of the GNU General Public License as published by
639 | the Free Software Foundation, either version 3 of the License, or
640 | (at your option) any later version.
641 |
642 | This program is distributed in the hope that it will be useful,
643 | but WITHOUT ANY WARRANTY; without even the implied warranty of
644 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
645 | GNU General Public License for more details.
646 |
647 | You should have received a copy of the GNU General Public License
648 | along with this program. If not, see .
649 |
650 | Also add information on how to contact you by electronic and paper mail.
651 |
652 | If the program does terminal interaction, make it output a short
653 | notice like this when it starts in an interactive mode:
654 |
655 | Copyright (C)
656 | This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
657 | This is free software, and you are welcome to redistribute it
658 | under certain conditions; type `show c' for details.
659 |
660 | The hypothetical commands `show w' and `show c' should show the appropriate
661 | parts of the General Public License. Of course, your program's commands
662 | might be different; for a GUI interface, you would use an "about box".
663 |
664 | You should also get your employer (if you work as a programmer) or school,
665 | if any, to sign a "copyright disclaimer" for the program, if necessary.
666 | For more information on this, and how to apply and follow the GNU GPL, see
667 | .
668 |
669 | The GNU General Public License does not permit incorporating your program
670 | into proprietary programs. If your program is a subroutine library, you
671 | may consider it more useful to permit linking proprietary applications with
672 | the library. If this is what you want to do, use the GNU Lesser General
673 | Public License instead of this License. But first, please read
674 | .
