The javahelp transformation runs several additional Ant targets after the XHTML processing is completed in order to create control files for the JavaHelp output.
There are two primary Ant targets:
dita.map.javahelp
: Creates all of the files that are needed to compile JavaHelp, including a table of contents, sorted index, and help map file.
compile.Java.Help
: Searches for a JavaHelp compiler on the system. If a compiler is found, the help project is compiled.
