-# This eclass provides the framework for ada lib installation with the split and
-# SLOTted gnat compilers (gnat-xxx, gnatbuild.eclass). Each lib gets built once
-# for every installed gnat compiler. Activation of a particular bunary module is
-# performed by eselect-gnat, when the active compiler gets switched
-#
-# The ebuilds should define the lib_compile and lib_install functions that are
-# called from the (exported) gnat_src_compile function of eclass. These
-# functions should operate similarly to the starndard src_compile and
-# src_install. The only difference, that they should use $SL variable instead of
-# $S (this is where the working copy of source is held) and $DL instead of $D as
-# its installation point.
-
-inherit flag-o-matic eutils multilib
-
-# The environment is set locally in src_compile and src_install functions
-# by the common code sourced here and in gnat-eselect module.
-# This is the standard location for this code (belongs to eselect-gnat,
-# since eselect should work even in the absense of portage tree and we can
-# guarantee to some extent presence of gnat-eselect when anything gnat-related
-# gets processed. See #192505)
-#
-# Note!
-# It may not be safe to source this at top level. Only source inside local
-# functions!
