@ -3479,6 +3479,10 @@ build file @file{build.xml} with tasks to build the specified jar
archive. In this case the parameter @code{#:source-dir} can be used to
specify the source sub-directory, defaulting to ``src''.
The @code{#:main-class} parameter can be used with the minimal ant
buildfile to specify the main class of the resulting jar. This makes the
jar file executable.
The parameter @code{#:build-target} can be used to specify the Ant task
that should be run during the @code{build} phase. By default the
``jar'' task will be run.
