<!-- This file builds a single jar file. It just sets defaults for the java
     compiler then invokes it.

     This is the only place we compile files.

     On entry we require:
       build.jar.file        Fully specified name of destination jar file.
       base.name             Defines the name of the source base.
       base.java.sources     Defines the java source files
       base.class.patternset Defines the java class files
       base.resource.files   Defines extra resources to go in the jar

     We will copy all files defined by base.java.patternset to a temporary
     location and compile out of that into a temporary classes location.

     We do that to avoid a problematic feature of the java compilers, the
     tendency to recompile any referenced sources found on the source path.

     So, if we have all our sources under the directory "src" and compile a
     single package in that tree, all referenced classes will be compiled,
     even if they exist in a jar file on the class path.

     The other side-effect is that we might compile and include classes we
     didn't realise we were compiling.

     The downside is that we need to be very specific about the classes we
     compile for a package and we might need to put classes in
     base.java.sources which we don't want in the final jar file.

     On exit we will have created classes in the directory
        ${jar.temp.classes}
     and a jar file
        ${build.jar.file}

      These properties control option settings on the Javac compiler when it

      compile.deprecation  Should compilation include the deprecation option?
