-Build
-=====  
-A JOSM plugin is built as a single jar. We use ant to build.
-
-See build.xml in this directory and update the plugin specific properties in the
-configuration section.
-  
-
-Maintaining versions
-====================
-There are two versions maintained with each plugin:
-   1) the main version
-      You have to manually set the plugins main version in the build script.
-      Set the property plugin.main.version in build.xml accordingly. 
-
-   2) the build version
-      The build version is unique for every build of the plugin. It is equal
-      to the SVN revision of your plugin directory. 
-
- Both the main version and the build version are included in properties of the plugins
- manifest:
-    Plugin-Version      the build version
-    Plugin-Mainversion  the main version
-
- JOSM automatically detects whether a plugin needs to be upgraded. It compares the build
- version of the currently installed plugin jar with the build version of the plugin jar in 
- the SVN. The main version is irrelevant for this process.  
- 
- Making your plugin available to JOSM users
- ===========================================
- When a plugin jar is checked into SVN a script updates the plugins list on the JOSM wiki:
-   http://josm.openstreetmap.de/wiki/Plugins
- JOSM retrieves the list of available plugins and their build versions from this list.
-
-            commit      publish               read
-                       meta data              meta data 
-      Build  ==>  SVN  =======>  JOSM Wiki   <======= JOSM 
-                   ^ 
-                   ==================================
-                            fetch current plugin jar 
- 
- Note that you have to manually publish (commit) your plugin jar. There is no nightly build
- in place. Everything else (pulishing meta data, updating plugins in the client) is then handled 
- by automatic processes.
