In http://fmpp.sourceforge.net/commandline.html, please
warn about possible problems when executing fmpp as
I just got the "The input line is too long." error when
directory structure is deep. ":gotAllArgs was
unexpected at this time."
This is a well-known bug on the ant windows side
but since you copy the ant lcp.bat, you might warn your
users that they might run into this!
