#   - ANT_HOME is the current directory (instead of parent)
#   - ignore external ANT_OPTS
#   - ignore external ANT_ARGS
#   - ignore external CLASSPATH
#   - set java stack size to 128 MB
#   - lower down verbosity (because the foreach task would be _very_ verbose
#     otherwise)
#

# explicit name our build file (may be replaced by a variable some time)
ANT_ARGS="-buildfile build.xml"

# lower down logger verbosity
ANT_ARGS="-logger org.apache.tools.ant.NoBannerLogger $ANT_ARGS"

# set regexp engine
ANT_ARGS="-Dant.regexp.regexpimpl=org.apache.tools.ant.util.regexp.JakartaOroRegexp $ANT_ARGS"

# raise heap/stack size...
ANT_OPTS="-Xmx128m -mx128m"

# set classpath
CLASSPATH=./lib

# set ant home directory (cwd)
ANT_HOME=.

# OS specific support.  $var _must_ be set to either true or false.
