Hi,

I have adapted the shell script that Ant uses to run itself into a shell
script that can be used to run FOP.

I have attached the 'fop' script.  This can potentially be a nice
replacement for the fop.sh script that FOP currently uses.

Benefit of this script:

1. For users of FOP that uses it as a command line utility, as in
   fop -fo myfile.fo -pdf myfile.pdf
there is no need to mess around with the CLASSPATH.  Simply add
/path/to/FOP-0.20.1 into the PATH, or create a symbolic like this:
   ln -s /path/to/Fop-0.20.1/fop /usr/bin/fop
and the fop command will simply work.

2. The ant script works with Cygwin, even if you install FOP into a
directory with a space in its name, like "C:\Program Files".  I haven't
tested it but it should work.

3. It brings in all jar files in the $FOP_HOME/lib directory.  So in the
future, there's no need to modify the fop script when some new library
is added to $FOP_HOME/lib.
