custbuild.xml

 <?eclipse.ant.import?>
 <!-- custom targets
-This file is included in build.xml whe exported from Eclipse
-Project tag does not need name/basedir/default attributes
+To customise:
+- Create a set of custom image files in a parallel directory structure to ./res
+and change 'res_sol' below to the directory name. Change filenames to be copied below as required.
+- Check changes in text below, and add your own.
+- In Eclipse do File->Export, Ant buildfiles, select project name, Finish. 
+This will create a build.xml file which will do an include on this one (because of the PI on the top line above)
+- Do ant custom to run the customisations
+- To build apk - in Eclipse do Project->Clean, then Run->Run As->Android application (this builds Release version of apk)
