[gmx-users] How to modify FF.dat?

[curtchr1 at iit.edu]

Sorry if this is in an FAQ somewhere, and if so, please point me in the
appropriate direction, but, aside from the file name, what other formating
procedures do I need to keep in mind if I wish to edit FF.dat, usually found
in:

/usr/local/gromacs/share/top/

Ex: I wish to include ffG50a1.itp, so in FF.dat I add:

ffG50a1 Gromacs (Description)

Does it matter whether I write Gromacs or Gromos96, and are there any other
script files I need to edit for this to work.  Thanks for anyone's time.
