Properties needed by your ant build can be specified here (in standard properties file format):

    # comment
    name1=value1
    name2=$VAR2

These are passed to Ant like `"-Dname1=value1 -Dname2=value2"`. Always use `$VAR` style for parameter references (do not use %VAR% style, even when build runs on Windows). Backslashes are used for escaping, so use `\\` for a single backslash. Double quotes (") should be avoided, as ant on *nix wraps parameters in quotes quotes and runs them through `eval`, and Windows has its own issues with escaping.. in either case, use of quotes may result in build failure. To define an empty property, simply write `varname=`
