REM   This file is derived from the ant-1.5.3 distribution

REM   +++ Changes for dedicated httpd documentation build +++
REM
REM   - no call of antrc_pre.bat and antrc_post.bat
REM   - DEFAULT_ANT_HOME is the current directory (instead of parent)
REM   - ignore external ANT_OPTS
REM   - ignore external ANT_ARGS
REM   - ignore external CLASSPATH
REM   - set java stack size to 128 MB
REM   - lower down verbosity (because the foreach task would be _very_ verbose
REM     otherwise)
REM   - use only bundled ant!
