# This patch from Debian rearranges some paths to match Linux conventions.
Patch0:         %{name}-paths.patch
# This patch applies a change from Debian to allow help files to be in gzip
# compressed DVI files, and also adds support for viewing with xdg-open.
Patch1:         %{name}-help.patch
# This patch will not be sent upstream.  It makes the main binary read the
# environment variables now read by gap.sh, so we can dispose of the shell
# script and run the actual binary directly.
Patch2:         %{name}-env.patch
# This patch was sent upstream 4 Aug 2011.  It fixes some cosmetic issues in
# the Emacs Lisp sources.

%description
GAP is a system for computational discrete algebra, with particular
emphasis on Computational Group Theory.  GAP provides a programming
language, a library of thousands of functions implementing algebraic
algorithms written in the GAP language as well as large data libraries
of algebraic objects.  GAP is used in research and teaching for studying
groups and their representations, rings, vector spaces, algebras,
combinatorial structures, and more.

This is a metapackage that requires the standard GAP components.
