  6 |    TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
  7 | 
  8 |    1. Definitions.
  9 | 
 10 |       "License" shall mean the terms and conditions for use, reproduction,
 11 |       and distribution as defined by Sections 1 through 9 of this document.
 12 | 
 13 |       "Licensor" shall mean the copyright owner or entity authorized by
 14 |       the copyright owner that is granting the License.
 15 | 
 16 |       "Legal Entity" shall mean the union of the acting entity and all
 17 |       other entities that control, are controlled by, or are under common
 18 |       control with that entity. For the purposes of this definition,
 19 |       "control" means (i) the power, direct or indirect, to cause the
 20 |       direction or management of such entity, whether by contract or
 21 |       otherwise, or (ii) ownership of fifty percent (50%) or more of the
 22 |       outstanding shares, or (iii) beneficial ownership of such entity.
 23 | 
 24 |       "You" (or "Your") shall mean an individual or Legal Entity
 25 |       exercising permissions granted by this License.
 26 | 
 27 |       "Source" form shall mean the preferred form for making modifications,
 28 |       including but not limited to software source code, documentation
 29 |       source, and configuration files.
 30 | 
 31 |       "Object" form shall mean any form resulting from mechanical
 32 |       transformation or translation of a Source form, including but
 33 |       not limited to compiled object code, generated documentation,
 34 |       and conversions to other media types.
 35 | 
 36 |       "Work" shall mean the work of authorship, whether in Source or
 37 |       Object form, made available under the License, as indicated by a
 38 |       copyright notice that is included in or attached to the work
 39 |       (an example is provided in the Appendix below).
 40 | 
 41 |       "Derivative Works" shall mean any work, whether in Source or Object
 42 |       form, that is based on (or derived from) the Work and for which the
 43 |       editorial revisions, annotations, elaborations, or other modifications
 44 |       represent, as a whole, an original work of authorship. For the purposes
 45 |       of this License, Derivative Works shall not include works that remain
 46 |       separable from, or merely link (or bind by name) to the interfaces of,
 47 |       the Work and Derivative Works thereof.
 48 | 
 49 |       "Contribution" shall mean any work of authorship, including
 50 |       the original version of the Work and any modifications or additions
 51 |       to that Work or Derivative Works thereof, that is intentionally
 52 |       submitted to Licensor for inclusion in the Work by the copyright owner
 53 |       or by an individual or Legal Entity authorized to submit on behalf of
 54 |       the copyright owner. For the purposes of this definition, "submitted"
 55 |       means any form of electronic, verbal, or written communication sent
 56 |       to the Licensor or its representatives, including but not limited to
 57 |       communication on electronic mailing lists, source code control systems,
 58 |       and issue tracking systems that are managed by, or on behalf of, the
 59 |       Licensor for the purpose of discussing and improving the Work, but
 60 |       excluding communication that is conspicuously marked or otherwise
 61 |       designated in writing by the copyright owner as "Not a Contribution."
 62 | 
 63 |       "Contributor" shall mean Licensor and any individual or Legal Entity
 64 |       on behalf of whom a Contribution has been received by Licensor and
 65 |       subsequently incorporated within the Work.
 66 | 
 67 |    2. Grant of Copyright License. Subject to the terms and conditions of
 68 |       this License, each Contributor hereby grants to You a perpetual,
 69 |       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
 70 |       copyright license to reproduce, prepare Derivative Works of,
 71 |       publicly display, publicly perform, sublicense, and distribute the
 72 |       Work and such Derivative Works in Source or Object form.
 73 | 
 74 |    3. Grant of Patent License. Subject to the terms and conditions of
 75 |       this License, each Contributor hereby grants to You a perpetual,
 76 |       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
 77 |       (except as stated in this section) patent license to make, have made,
 78 |       use, offer to sell, sell, import, and otherwise transfer the Work,
 79 |       where such license applies only to those patent claims licensable
 80 |       by such Contributor that are necessarily infringed by their
 81 |       Contribution(s) alone or by combination of their Contribution(s)
 82 |       with the Work to which such Contribution(s) was submitted. If You
 83 |       institute patent litigation against any entity (including a
 84 |       cross-claim or counterclaim in a lawsuit) alleging that the Work
 85 |       or a Contribution incorporated within the Work constitutes direct
 86 |       or contributory patent infringement, then any patent licenses
 87 |       granted to You under this License for that Work shall terminate
 88 |       as of the date such litigation is filed.
 89 | 
 90 |    4. Redistribution. You may reproduce and distribute copies of the
 91 |       Work or Derivative Works thereof in any medium, with or without
 92 |       modifications, and in Source or Object form, provided that You
 93 |       meet the following conditions:
 94 | 
 95 |       (a) You must give any other recipients of the Work or
 96 |           Derivative Works a copy of this License; and
 97 | 
 98 |       (b) You must cause any modified files to carry prominent notices
 99 |           stating that You changed the files; and
100 | 
101 |       (c) You must retain, in the Source form of any Derivative Works
102 |           that You distribute, all copyright, patent, trademark, and
103 |           attribution notices from the Source form of the Work,
104 |           excluding those notices that do not pertain to any part of
105 |           the Derivative Works; and
106 | 
107 |       (d) If the Work includes a "NOTICE" text file as part of its
108 |           distribution, then any Derivative Works that You distribute must
109 |           include a readable copy of the attribution notices contained
110 |           within such NOTICE file, excluding those notices that do not
111 |           pertain to any part of the Derivative Works, in at least one
112 |           of the following places: within a NOTICE text file distributed
113 |           as part of the Derivative Works; within the Source form or
114 |           documentation, if provided along with the Derivative Works; or,
115 |           within a display generated by the Derivative Works, if and
116 |           wherever such third-party notices normally appear. The contents
117 |           of the NOTICE file are for informational purposes only and
118 |           do not modify the License. You may add Your own attribution
119 |           notices within Derivative Works that You distribute, alongside
120 |           or as an addendum to the NOTICE text from the Work, provided
121 |           that such additional attribution notices cannot be construed
122 |           as modifying the License.
123 | 
124 |       You may add Your own copyright statement to Your modifications and
125 |       may provide additional or different license terms and conditions
126 |       for use, reproduction, or distribution of Your modifications, or
127 |       for any such Derivative Works as a whole, provided Your use,
128 |       reproduction, and distribution of the Work otherwise complies with
129 |       the conditions stated in this License.
130 | 
131 |    5. Submission of Contributions. Unless You explicitly state otherwise,
132 |       any Contribution intentionally submitted for inclusion in the Work
133 |       by You to the Licensor shall be under the terms and conditions of
134 |       this License, without any additional terms or conditions.
135 |       Notwithstanding the above, nothing herein shall supersede or modify
136 |       the terms of any separate license agreement you may have executed
137 |       with Licensor regarding such Contributions.
138 | 
139 |    6. Trademarks. This License does not grant permission to use the trade
140 |       names, trademarks, service marks, or product names of the Licensor,
141 |       except as required for reasonable and customary use in describing the
142 |       origin of the Work and reproducing the content of the NOTICE file.
143 | 
144 |    7. Disclaimer of Warranty. Unless required by applicable law or
145 |       agreed to in writing, Licensor provides the Work (and each
146 |       Contributor provides its Contributions) on an "AS IS" BASIS,
147 |       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
148 |       implied, including, without limitation, any warranties or conditions
149 |       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
150 |       PARTICULAR PURPOSE. You are solely responsible for determining the
151 |       appropriateness of using or redistributing the Work and assume any
152 |       risks associated with Your exercise of permissions under this License.
153 | 
154 |    8. Limitation of Liability. In no event and under no legal theory,
155 |       whether in tort (including negligence), contract, or otherwise,
156 |       unless required by applicable law (such as deliberate and grossly
157 |       negligent acts) or agreed to in writing, shall any Contributor be
158 |       liable to You for damages, including any direct, indirect, special,
159 |       incidental, or consequential damages of any character arising as a
160 |       result of this License or out of the use or inability to use the
161 |       Work (including but not limited to damages for loss of goodwill,
162 |       work stoppage, computer failure or malfunction, or any and all
163 |       other commercial damages or losses), even if such Contributor
164 |       has been advised of the possibility of such damages.
165 | 
166 |    9. Accepting Warranty or Additional Liability. While redistributing
167 |       the Work or Derivative Works thereof, You may choose to offer,
168 |       and charge a fee for, acceptance of support, warranty, indemnity,
169 |       or other liability obligations and/or rights consistent with this
170 |       License. However, in accepting such obligations, You may act only
171 |       on Your own behalf and on Your sole responsibility, not on behalf
172 |       of any other Contributor, and only if You agree to indemnify,
173 |       defend, and hold each Contributor harmless for any liability
174 |       incurred by, or claims asserted against, such Contributor by reason
175 |       of your accepting any such warranty or additional liability.
176 | 
177 |    END OF TERMS AND CONDITIONS
178 | 
179 |    APPENDIX: How to apply the Apache License to your work.
180 | 
181 |       To apply the Apache License to your work, attach the following
182 |       boilerplate notice, with the fields enclosed by brackets "[]"
183 |       replaced with your own identifying information. (Don't include
184 |       the brackets!)  The text should be enclosed in the appropriate
185 |       comment syntax for the file format. We also recommend that a
186 |       file or class name and description of purpose be included on the
187 |       same "printed page" as the copyright notice for easier
188 |       identification within third-party archives.
189 | 
190 |    Copyright [yyyy] [name of copyright owner]

192 |    Licensed under the Apache License, Version 2.0 (the "License");
193 |    you may not use this file except in compliance with the License.

 1 | # Garrett
 2 | 
 3 | Garrett is an example application for Mirah development on Android.
 4 | 
 5 | Garrett is named after Garrett P. Serviss, the hero of Edison's
 6 | Conquest of Mars, a ridiculous late 19th-century space opera novel by
 7 | Garrett P. Serviss.
 8 | 
 9 | ## Compilation
10 | 
11 | Install [JRuby](http://jruby.org) and then
12 | [pindah](http://github.com/mirah/pindah). If your gem and rake are not
13 | from from JRuby, prefix the commands with jruby -S:
14 | 
15 |     $ gem install pindah
16 | 
17 | Then you should be able to build the apk with rake:
18 | 
19 |     $ rake debug
20 |     
21 | This places <tt>Garrett-debug.apk</tt> in the <tt>bin/</tt>
22 | directory. You can install it to a connected device or emulator with
23 | <tt>rake install</tt> or distribute for HTTP download or whatever.
