Well, if you're a bit familiar with Sage / Python and the shell, take a
look at
build/pkgs/gap_packages/spkg-install (a shell script)
and
src/sage/interfaces/gap.py (especially gap_reset_workspace(), line
1486 ff.)
The wiki page you mentioned is probably outdated, as it was last updated
in 2013.
The first file above starts with
# WARNING -- if you add a package here, also add it to
# the gap_reset_workspace() command in
# <SAGE_ROOT>/src/sage/interfaces/gap.py
but AFAICS not all of the GAP packages from the current optional
gap_packages package are actually listed / treated there, no idea why.
Otherwise it *may* perhaps help to delete all old GAP workspaces (by
default in $HOME/.sage/gap/) *before* (re)starting Sage, then calling
gap_reset_workspace() again.
If I'm not mistaken, you could afterwards load the GAP packages you
want, before calling gap_reset_workspace() once again, in order to make
them part of your saved workspace.
