DESCRIPTION="Manage the installed gnat compilers"

# "inheriting" common stuff
# this crude sourcing has to stay the way it is, as common code
# cannot be part of some eclass (bug #192505)

### Phylosophy
# Each gnat installs a "specs" file named ${ARCH}-${PN}-${SLOT} under ${SPECSDIR}
# Each lib creates a dir with its name under ${SPECSDIR} and populates it with
# similar specs files (same name scheme)
# Recognizing gnat specs from lib specs is then eazy - test entry for being a
# dir, then just check what gnat profiles are installed for each lib..
# doset then creates env file that combines settings for gnat and for the
# corresponding profile of each installed lib..
### Helpers
# return *the* name of the active profile, checking that we do not have multiple
# env files.
# There can be only one!
