Subject Re: Deriving something from <srcfile/> from within <apply>
Date Thu, 06 Apr 2006 15:59:06 GMT
So your utility requires, for the file "foo.in", e.g.:

utility foo.in blahfoo.in

but the target file is determined automatically?
(<mapper> w/o <targetfile>)

In this case I might have to recommend antcontrib's
<for>.  Even if we added the ability to duplicate
<srcfile> and/or <targetfile>, "foo.in" would still be
a separate argument from "blah".
