Re: [Embedlets-dev] [outhouse] ant build script

[Brill P. <bri...@ro...>]

For a good example of this, see the japl/build.xml
When you first build the platform-jstamp module, it will ask you to enter
the path to the ajile directiory... it then saves that for future use and
adds the aJile runtime to your classpath.
