-#   May 2007:
-#     Made bsfix make one pass for all things and add some glocal targets for
-#     setting up the whole thing. Contributed by  kiorky
-#     (kiorky@cryptelium.net).
-#   December 2006:
-#     I pretty much rewrote the logic of the bsfix functions
-#     and xml-rewrite.py because they were so slow

-# @BLURB: eclass for ant based Java packages
-# @DESCRIPTION:
-# Eclass for Ant-based Java packages. Provides support for both automatic and
-# manual manipulation of build.xml files. Should be inherited after java-pkg-2
-# or java-pkg-opt-2 eclass.
-
-inherit java-utils-2 multilib
-
-# This eclass provides functionality for Java packages which use
-# ant to build. In particular, it will attempt to fix build.xml files, so that
-# they use the appropriate 'target' and 'source' attributes.
-
-# @ECLASS-VARIABLE: WANT_ANT_TASKS
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# An $IFS separated list of ant tasks.
-# Ebuild can specify this variable before inheriting java-ant-2 eclass to
-# determine ANT_TASKS it needs. They will be automatically translated to
-# DEPEND variable and ANT_TASKS variable. JAVA_PKG_FORCE_ANT_TASKS can override
-# ANT_TASKS set by WANT_ANT_TASKS, but not the DEPEND due to caching.
-# Ebuilds that need to depend conditionally on certain tasks and specify them
-# differently for different eant calls can't use this simplified approach.
-# You also cannot specify version or anything else than ant-*.
-#
-# @CODE
-# WANT_ANT_TASKS="ant-junit ant-trax"
-# @CODE
-
-#The implementation of dependencies is handled by java-utils-2.eclass
-#WANT_ANT_TASKS
-
-# @ECLASS-VARIABLE: JAVA_ANT_DISABLE_ANT_CORE_DEP
-# @DEFAULT_UNSET

-# Setting this variable non-empty before inheriting java-ant-2 disables adding
-# dev-java/ant-core into DEPEND.
