# This file mainly provides the `mathcomp` derivation, which is            #
# essentially a meta-package containing all core mathcomp libraries        #
# (ssreflect fingroup algebra solvable field character). They can be       #
# accessed individually through the passthrough attributes of mathcomp     #
# bearing the same names (mathcomp.ssreflect, etc).                        #
############################################################################
# Compiling a custom version of mathcomp using `mathcomp.override`.        #
# This is the replacement for the former `mathcomp_ config` function.      #
# See the documentation at doc/languages-frameworks/coq.section.md.        #
