# GPRESENT

## DESCRIPTION

gpresent is a package for making presentations with groff and
acroread.  It consist of a set of macros to be used with groff
and a post-processor for manipulating the PostScript output of
groff.  Without the use of the PAUSE macro, it can also be used
for making slides.

This Git repository has been set up as a fork of the
[original gpresent sources by
Bob Diertens](https://staff.fnwi.uva.nl/b.diertens/useful/gpresent/)
since they have not been updated in a while.
It will run on recent versions of Groff.
