# The packages aren't really required, but GAP tries to load them
# automatically, and will complain to the user if they fail to load.
# The list of automatically-loaded packages is a user preference, called
# AutoloadPackages, and the upstream default can be found in
# lib/package.gi within the GAP source tree. Passing "-A" to GAP on the
# CLI (or setting that user preference) will suppress the autoload
# behavior and allow GAP to start without these, which is why we allow
# the user to skip them with USE=minimal if he knows what he is doing.
