Java based build tool like make - optional libraries

 Apache Ant is a Java library and command-line tool whose mission is to drive
 processes described in build files as targets and extension points dependent
 upon each other. The main known usage of Ant is the build of Java applications.
 Ant supplies a number of built-in tasks allowing to compile, assemble, test
 and run Java applications. Ant can also be used effectively to build non Java
 applications, for instance C or C++ applications. More generally, Ant can be
 used to pilot any type of process which can be described in terms of targets
 and tasks.

 This package contains the optional tasks libraries.
