Useful to protect your staging and production instances. 23 | 24 | How this can be useful for me? 25 | ------------------------------ 26 | 27 | It will be useful whenever you want to protect whole or part of website 28 | from being public. See following examples for staging and production 29 | instances. 30 | 31 | **For staging instances** 32 | 33 | You will find restrictfe useful if you have staging instances and you want to 34 | protect frontend content form public but at the same time: 35 | 36 | - allow to show frontend to authorized backend users, 37 | - allow to show frontend to IP of your VPN, 38 | - allow to show frontend to your external spiders for crawling, 39 | - allow some payment systems to send confirm link to your application endpoint, 40 | - allow Google Page Speed to make tests, 41 | - etc. 42 | 43 | **For production instances** 44 | 45 | You will find restrictfe useful if you have production instance which is 46 | already live but access to some part of website must be yet hidden for 47 | regular frontend users. At the same time is must be accessible in 48 | frontend for logged backend users which must be able to edit content on 49 | that hidden part. 50 | 51 | Installation 52 | ------------ 53 | 54 | Just use composer or download by Extension Manager. 55 | 56 | :: 57 | 58 | composer require sourcebroker/restrictfe 59 | 60 | Be aware that after installation restrictfe blocks all traffic to 61 | frontend by default. This is by design because if you will add new 62 | staging instances they will be blocked by default so there is no risk 63 | that you forgot to protect it and someone will see new staging instance 64 | or google will index it. Of course you must remember to unblock 65 | production instance with simple line: 66 | 67 | :: 68 | 69 | $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['restrictfe']['exceptions'] = ['*' => true]; 70 | 71 | Put this config in the file that is included only on live instance! 72 | 73 | **Notice!** 74 | restrictfe protection is not working if $_SERVER['REMOTE_ADDR'] == 127.0.0.1 so if you 75 | are working on your local instance restrictfe is disabled. If you want to to make testing 76 | and enable it on your local instance insert following line in typo3conf/AdditionalConfiguration.php 77 | or in some extension ext_localconf.php: 78 | ``$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['restrictfe']['exceptions']['ip'] = '__UNSET';`` 79 | 80 | 81 | Documentation 82 | ------------- 83 | 84 | Exceptions 85 | ~~~~~~~~~~ 86 | 87 | As stated earlier restrictfe blocks all traffic to frontend and we must 88 | set exceptions that will allow to see the frontend. Those exceptions 89 | conditions are written in 90 | ``$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['restrictfe']['exceptions']`` 91 | array. By default on first level conditions are joined with logical OR 92 | but you can join them with AND if you will make AND array key and 93 | conditions inside. You can nest OR/AND conditions inside arrays. Values 94 | of conditions can be string or array. If its array its OR'ed. Some 95 | conditions can be negated. In such case the conditions inside are 96 | AND'ed. 97 | 98 | **The result of this condition checks is used to decide if frontend 99 | should be blocked or not. If its true then frontend is not blocked.** 100 | 101 | Conditions 102 | ~~~~~~~~~~ 103 | 104 | backendUser 105 | +++++++++++ 106 | 107 | - | *Argument* 108 | | Activate (boolean) 109 | 110 | - *Note* 111 | 112 | - If activated then frontend will be visible to authorized backend 113 | users. Only single authorization is needed and user can log out 114 | because special cookie will allow him to see frontend. That also 115 | means that BE user can unlog from backend and still see the 116 | frontend - its crucial for good testing of caching bugs. 117 | 118 | - For backend user you can check “Clear BE session after login” in 119 | backend user record. This will unlog BE user from backend just 120 | after authorization. This is useful if you want to create only 121 | kind of "preview" BE user. This user does not need to have access 122 | to any BE module and do not needs rights to read/write any table. 123 | 124 | - As stated in last points after backend user authorization special 125 | cookie is set that allows to access frontend even after backend 126 | user will be logged off. You can set each aspect of this cookie by 127 | setting ``$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['restrictfe']['cookie']`` 128 | array. For example you can set the cookie for multiple subdomains 129 | which means that user needs to authorize only once to have access 130 | to all protected subdomains. With htaccess password user would 131 | need to authorize to each subdomain independently. Example: 132 | ``$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['restrictfe']['cookie']['domain'] = '.example.com';`` 133 | 134 | - *Example* 135 | 136 | :: 137 | 138 | $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['restrictfe']['exceptions'] = [ 139 | backendUser' => true 140 | ]; 141 | 142 | domain 143 | ++++++ 144 | 145 | - | *Argument* 146 | | Domain name (string) 147 | 148 | - | *Note* 149 | | You can negate this condition with !domain. 150 | 151 | - | *Example* 152 | | Allow frontend access to all except traffic to domain sub.example.com 153 | 154 | :: 155 | 156 | $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['restrictfe']['exceptions'] = [ 157 | '!domain' => ['sub.example.com'] 158 | ]; 159 | 160 | get 161 | +++ 162 | 163 | - | *Argument* 164 | | "getName=getValue" pairs (string) 165 | 166 | - | *Note* 167 | | You can negate this condition with !get. 168 | 169 | - | *Example* 170 | | Allow only request with GET param secret=999 to access frontend. 171 | 172 | :: 173 | 174 | $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['restrictfe']['exceptions'] = [ 175 | 'get' => 'secret=999' 176 | ]; 177 | 178 | header 179 | ++++++ 180 | 181 | - | *Argument* 182 | | "headerName=headerValue" pairs (string) 183 | 184 | - | *Note* 185 | | You can negate this condition with !header. 186 | 187 | - | *Example* 188 | | Allow only request with HTTP header MYHEADER=99 to access frontend. 189 | 190 | :: 191 | 192 | $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['restrictfe']['exceptions'] = [ 193 | 'header' => 'MYHEADER=99' 194 | ]; 195 | 196 | ip 197 | ++ 198 | 199 | - | *Argument* 200 | | Single IP with mask (string), comma separated list of IPs with 201 | mask(string), array of IPs with mask (array string) 202 | 203 | - | *Note* 204 | | In the background a ``GeneralUtility::cmpIP()`` is used so you can 205 | use \* and mask for IP like 12.12.45.\* or 13.55.0.0/16. 206 | | You can negate this condition with !ip. 207 | 208 | - | *Example* 209 | | Allow frontend access only for IP 11.11.11.11 or 22.22.22.22 or 33.33.33.33 210 | 211 | :: 212 | 213 | $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['restrictfe']['exceptions'] = [ 214 | 'ip' => [ 215 | '11.11.11.11', // ip of developers VPN 216 | '22.22.22.22' // ip of client VPN 217 | '33.33.33.33' // payment system confirm request 218 | ] 219 | ]; 220 | 221 | 222 | Block frontend access to traffic from IP range 34.34.0.0/16 223 | 224 | :: 225 | 226 | $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['restrictfe']['exceptions'] = [ 227 | '!ip' => [ 228 | '34.34.0.0/16', // some not trusted network 229 | ] 230 | ]; 231 | 232 | post 233 | ++++ 234 | 235 | - | *Argument* 236 | | "getName=getValue" pairs (string) 237 | 238 | - | *Note* 239 | | You can negate this condition with !post. 240 | 241 | - | *Example* 242 | | Allow only request with POST param secret=999 to access frontend. 243 | 244 | :: 245 | 246 | $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['restrictfe']['exceptions'] = [ 247 | 'post' => 'secret=999' 248 | ]; 249 | 250 | requestUri 251 | ++++++++++ 252 | 253 | - | *Argument* 254 | | uri part after domain without leading slash (string) 255 | 256 | - | *Note* 257 | | You can negate this condition with !requestUri.

The frontend is not blocked at all. What is wrong?** 364 | Be sure you are logged from BE and the cookie "restrictfe" is deleted. Remember also that 365 | restrictfe protection is not working if $_SERVER['REMOTE_ADDR'] == 127.0.0.1 so if you 366 | are working on your local instance restrictfe is disabled. To enable it on your local instance 367 | insert folowing line: 368 | ``$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['restrictfe']['exceptions']['ip'] = '__UNSET';`` 369 | 370 | - **I am logged out from BE but still frontend is not blocked, why?** 371 | From 3.0.0. version after first successful login a cookie is set 372 | (name tx\_restrictfe). If that cookie is present then user do not 373 | have to authorize again. So delete that cookie and then your frontend 374 | should be blocked again. 375 | 376 | 377 | Known problems 378 | -------------- 379 | 380 | None. 381 | 382 | To-Do list 383 | ---------- 384 | 385 | 1.

By contrast, the GNU General Public 13 | License is intended to guarantee your freedom to share and change free 14 | software--to make sure the software is free for all its users. This 15 | General Public License applies to most of the Free Software 16 | Foundation's software and to any other program whose authors commit to 17 | using it. (Some other Free Software Foundation software is covered by 18 | the GNU Lesser General Public License instead.) You can apply it to 19 | your programs, too. 20 | 21 | When we speak of free software, we are referring to freedom, not 22 | price. Our General Public Licenses are designed to make sure that you 23 | have the freedom to distribute copies of free software (and charge for 24 | this service if you wish), that you receive source code or can get it 25 | if you want it, that you can change the software or use pieces of it 26 | in new free programs; and that you know you can do these things. 27 | 28 | To protect your rights, we need to make restrictions that forbid 29 | anyone to deny you these rights or to ask you to surrender the rights. 30 | These restrictions translate to certain responsibilities for you if you 31 | distribute copies of the software, or if you modify it. 32 | 33 | For example, if you distribute copies of such a program, whether 34 | gratis or for a fee, you must give the recipients all the rights that 35 | you have. You must make sure that they, too, receive or can get the 36 | source code. And you must show them these terms so they know their 37 | rights. 38 | 39 | We protect your rights with two steps: (1) copyright the software, and 40 | (2) offer you this license which gives you legal permission to copy, 41 | distribute and/or modify the software. 42 | 43 | Also, for each author's protection and ours, we want to make certain 44 | that everyone understands that there is no warranty for this free 45 | software. If the software is modified by someone else and passed on, we 46 | want its recipients to know that what they have is not the original, so 47 | that any problems introduced by others will not reflect on the original 48 | authors' reputations. 49 | 50 | Finally, any free program is threatened constantly by software 51 | patents. We wish to avoid the danger that redistributors of a free 52 | program will individually obtain patent licenses, in effect making the 53 | program proprietary. To prevent this, we have made it clear that any 54 | patent must be licensed for everyone's free use or not licensed at all. 55 | 56 | The precise terms and conditions for copying, distribution and 57 | modification follow. 58 | 59 | GNU GENERAL PUBLIC LICENSE 60 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 61 | 62 | 0. This License applies to any program or other work which contains 63 | a notice placed by the copyright holder saying it may be distributed 64 | under the terms of this General Public License. The "Program", below, 65 | refers to any such program or work, and a "work based on the Program" 66 | means either the Program or any derivative work under copyright law: 67 | that is to say, a work containing the Program or a portion of it, 68 | either verbatim or with modifications and/or translated into another 69 | language. (Hereinafter, translation is included without limitation in 70 | the term "modification".) Each licensee is addressed as "you". 71 | 72 | Activities other than copying, distribution and modification are not 73 | covered by this License; they are outside its scope. The act of 74 | running the Program is not restricted, and the output from the Program 75 | is covered only if its contents constitute a work based on the 76 | Program (independent of having been made by running the Program). 77 | Whether that is true depends on what the Program does. 78 | 79 | 1. You may copy and distribute verbatim copies of the Program's 80 | source code as you receive it, in any medium, provided that you 81 | conspicuously and appropriately publish on each copy an appropriate 82 | copyright notice and disclaimer of warranty; keep intact all the 83 | notices that refer to this License and to the absence of any warranty; 84 | and give any other recipients of the Program a copy of this License 85 | along with the Program. 86 | 87 | You may charge a fee for the physical act of transferring a copy, and 88 | you may at your option offer warranty protection in exchange for a fee. 89 | 90 | 2. You may modify your copy or copies of the Program or any portion 91 | of it, thus forming a work based on the Program, and copy and 92 | distribute such modifications or work under the terms of Section 1 93 | above, provided that you also meet all of these conditions: 94 | 95 | a) You must cause the modified files to carry prominent notices 96 | stating that you changed the files and the date of any change. 97 | 98 | b) You must cause any work that you distribute or publish, that in 99 | whole or in part contains or is derived from the Program or any 100 | part thereof, to be licensed as a whole at no charge to all third 101 | parties under the terms of this License. 102 | 103 | c) If the modified program normally reads commands interactively 104 | when run, you must cause it, when started running for such 105 | interactive use in the most ordinary way, to print or display an 106 | announcement including an appropriate copyright notice and a 107 | notice that there is no warranty (or else, saying that you provide 108 | a warranty) and that users may redistribute the program under 109 | these conditions, and telling the user how to view a copy of this 110 | License. (Exception: if the Program itself is interactive but 111 | does not normally print such an announcement, your work based on 112 | the Program is not required to print an announcement.) 113 | 114 | These requirements apply to the modified work as a whole. If 115 | identifiable sections of that work are not derived from the Program, 116 | and can be reasonably considered independent and separate works in 117 | themselves, then this License, and its terms, do not apply to those 118 | sections when you distribute them as separate works. But when you 119 | distribute the same sections as part of a whole which is a work based 120 | on the Program, the distribution of the whole must be on the terms of 121 | this License, whose permissions for other licensees extend to the 122 | entire whole, and thus to each and every part regardless of who wrote it. 123 | 124 | Thus, it is not the intent of this section to claim rights or contest 125 | your rights to work written entirely by you; rather, the intent is to 126 | exercise the right to control the distribution of derivative or 127 | collective works based on the Program. 128 | 129 | In addition, mere aggregation of another work not based on the Program 130 | with the Program (or with a work based on the Program) on a volume of 131 | a storage or distribution medium does not bring the other work under 132 | the scope of this License. 133 | 134 | 3. You may copy and distribute the Program (or a work based on it, 135 | under Section 2) in object code or executable form under the terms of 136 | Sections 1 and 2 above provided that you also do one of the following: 137 | 138 | a) Accompany it with the complete corresponding machine-readable 139 | source code, which must be distributed under the terms of Sections 140 | 1 and 2 above on a medium customarily used for software interchange; or, 141 | 142 | b) Accompany it with a written offer, valid for at least three 143 | years, to give any third party, for a charge no more than your 144 | cost of physically performing source distribution, a complete 145 | machine-readable copy of the corresponding source code, to be 146 | distributed under the terms of Sections 1 and 2 above on a medium 147 | customarily used for software interchange; or, 148 | 149 | c) Accompany it with the information you received as to the offer 150 | to distribute corresponding source code. (This alternative is 151 | allowed only for noncommercial distribution and only if you 152 | received the program in object code or executable form with such 153 | an offer, in accord with Subsection b above.) 154 | 155 | The source code for a work means the preferred form of the work for 156 | making modifications to it. For an executable work, complete source 157 | code means all the source code for all modules it contains, plus any 158 | associated interface definition files, plus the scripts used to 159 | control compilation and installation of the executable. However, as a 160 | special exception, the source code distributed need not include 161 | anything that is normally distributed (in either source or binary 162 | form) with the major components (compiler, kernel, and so on) of the 163 | operating system on which the executable runs, unless that component 164 | itself accompanies the executable. 165 | 166 | If distribution of executable or object code is made by offering 167 | access to copy from a designated place, then offering equivalent 168 | access to copy the source code from the same place counts as 169 | distribution of the source code, even though third parties are not 170 | compelled to copy the source along with the object code. 171 | 172 | 4. You may not copy, modify, sublicense, or distribute the Program 173 | except as expressly provided under this License. Any attempt 174 | otherwise to copy, modify, sublicense or distribute the Program is 175 | void, and will automatically terminate your rights under this License. 176 | However, parties who have received copies, or rights, from you under 177 | this License will not have their licenses terminated so long as such 178 | parties remain in full compliance. 179 | 180 | 5. You are not required to accept this License, since you have not 181 | signed it. However, nothing else grants you permission to modify or 182 | distribute the Program or its derivative works. These actions are 183 | prohibited by law if you do not accept this License. Therefore, by 184 | modifying or distributing the Program (or any work based on the 185 | Program), you indicate your acceptance of this License to do so, and 186 | all its terms and conditions for copying, distributing or modifying 187 | the Program or works based on it. 188 | 189 | 6. Each time you redistribute the Program (or any work based on the 190 | Program), the recipient automatically receives a license from the 191 | original licensor to copy, distribute or modify the Program subject to 192 | these terms and conditions. You may not impose any further 193 | restrictions on the recipients' exercise of the rights granted herein. 194 | You are not responsible for enforcing compliance by third parties to 195 | this License. 196 | 197 | 7. If, as a consequence of a court judgment or allegation of patent 198 | infringement or for any other reason (not limited to patent issues), 199 | conditions are imposed on you (whether by court order, agreement or 200 | otherwise) that contradict the conditions of this License, they do not 201 | excuse you from the conditions of this License. If you cannot 202 | distribute so as to satisfy simultaneously your obligations under this 203 | License and any other pertinent obligations, then as a consequence you 204 | may not distribute the Program at all. For example, if a patent 205 | license would not permit royalty-free redistribution of the Program by 206 | all those who receive copies directly or indirectly through you, then 207 | the only way you could satisfy both it and this License would be to 208 | refrain entirely from distribution of the Program. 209 | 210 | If any portion of this section is held invalid or unenforceable under 211 | any particular circumstance, the balance of the section is intended to 212 | apply and the section as a whole is intended to apply in other 213 | circumstances. 214 | 215 | It is not the purpose of this section to induce you to infringe any 216 | patents or other property right claims or to contest validity of any 217 | such claims; this section has the sole purpose of protecting the 218 | integrity of the free software distribution system, which is 219 | implemented by public license practices. Many people have made 220 | generous contributions to the wide range of software distributed 221 | through that system in reliance on consistent application of that 222 | system; it is up to the author/donor to decide if he or she is willing 223 | to distribute software through any other system and a licensee cannot 224 | impose that choice. 225 | 226 | This section is intended to make thoroughly clear what is believed to 227 | be a consequence of the rest of this License. 228 | 229 | 8. If the distribution and/or use of the Program is restricted in 230 | certain countries either by patents or by copyrighted interfaces, the 231 | original copyright holder who places the Program under this License 232 | may add an explicit geographical distribution limitation excluding 233 | those countries, so that distribution is permitted only in or among 234 | countries not thus excluded. In such case, this License incorporates 235 | the limitation as if written in the body of this License. 236 | 237 | 9. The Free Software Foundation may publish revised and/or new versions 238 | of the General Public License from time to time. Such new versions will 239 | be similar in spirit to the present version, but may differ in detail to 240 | address new problems or concerns. 241 | 242 | Each version is given a distinguishing version number. If the Program 243 | specifies a version number of this License which applies to it and "any 244 | later version", you have the option of following the terms and conditions 245 | either of that version or of any later version published by the Free 246 | Software Foundation. If the Program does not specify a version number of 247 | this License, you may choose any version ever published by the Free Software 248 | Foundation. 249 | 250 | 10. If you wish to incorporate parts of the Program into other free 251 | programs whose distribution conditions are different, write to the author 252 | to ask for permission. For software which is copyrighted by the Free 253 | Software Foundation, write to the Free Software Foundation; we sometimes 254 | make exceptions for this. Our decision will be guided by the two goals 255 | of preserving the free status of all derivatives of our free software and 256 | of promoting the sharing and reuse of software generally. 257 | 258 | NO WARRANTY 259 | 260 | 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 261 | FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 262 | OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 263 | PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 264 | OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 265 | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 266 | TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 267 | PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 268 | REPAIR OR CORRECTION. 269 | 270 | 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 271 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 272 | REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 273 | INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 274 | OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 275 | TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 276 | YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 277 | PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 278 | POSSIBILITY OF SUCH DAMAGES. 279 | 280 | END OF TERMS AND CONDITIONS 281 | 282 | How to Apply These Terms to Your New Programs 283 | 284 | If you develop a new program, and you want it to be of the greatest 285 | possible use to the public, the best way to achieve this is to make it 286 | free software which everyone can redistribute and change under these terms. 287 | 288 | To do so, attach the following notices to the program. It is safest 289 | to attach them to the start of each source file to most effectively 290 | convey the exclusion of warranty; and each file should have at least 291 | the "copyright" line and a pointer to where the full notice is found. 292 | 293 | 294 | Copyright (C) 295 | 296 | This program is free software; you can redistribute it and/or modify 297 | it under the terms of the GNU General Public License as published by 298 | the Free Software Foundation; either version 2 of the License, or 299 | (at your option) any later version. 300 | 301 | This program is distributed in the hope that it will be useful, 302 | but WITHOUT ANY WARRANTY; without even the implied warranty of 303 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 304 | GNU General Public License for more details. 305 | 306 | You should have received a copy of the GNU General Public License along 307 | with this program; if not, write to the Free Software Foundation, Inc., 308 | 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. 309 | 310 | Also add information on how to contact you by electronic and paper mail. 311 | 312 | If the program is interactive, make it output a short notice like this 313 | when it starts in an interactive mode: 314 | 315 | Gnomovision version 69, Copyright (C) year name of author 316 | Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 317 | This is free software, and you are welcome to redistribute it 318 | under certain conditions; type `show c' for details. 319 | 320 | The hypothetical commands `show w' and `show c' should show the appropriate 321 | parts of the General Public License. Of course, the commands you use may 322 | be called something other than `show w' and `show c'; they could even be 323 | mouse-clicks or menu items--whatever suits your program. 324 | 325 | You should also get your employer (if you work as a programmer) or your 326 | school, if any, to sign a "copyright disclaimer" for the program, if 327 | necessary. Here is a sample; alter the names: 328 | 329 | Yoyodyne, Inc., hereby disclaims all copyright interest in the program 330 | `Gnomovision' (which makes passes at compilers) written by James Hacker. 331 | 332 | , 1 April 1989 333 | Ty Coon, President of Vice 334 | 335 | This General Public License does not permit incorporating your program into 336 | proprietary programs. If your program is a subroutine library, you may 337 | consider it more useful to permit linking proprietary applications with the 338 | library. If this is what you want to do, use the GNU Lesser General 339 | Public License instead of this License. --------------------------------------------------------------------------------
