# Purpose: Contains common vars/locations and functions for use by gnat.eclass,
# gnat.eselect and gnatbuild.eclass.
#
# NOTE!!!
# This code should just define vars (try to limit these!) and simple functions.
# No bash extensions!!
# That is, no portage or eclass constructs are allowed!

## Lib install locations

## Gnat profile dependent files go under under ${LibTop}/${Gnat_Profile}/${PN}

## or $(profile2libdir ${profile}) in this code, eselect module or anywhere
## outside portage (as profile will be available only during actual execution, this only should
## be done inside corresponding functions).
