-# @AUTHOR:
-# Author Justin Lecher <jlec@gentoo.org>
-# Test functions provided by Sebastien Fabbro and Kacper Kowalik
-# @BLURB: Simplify fortran compiler management
-# @DESCRIPTION:
-# If you need a fortran compiler, then you should be inheriting this eclass.
-# In case you only need optional support, please export FORTRAN_NEEDED before
-# inheriting the eclass.
-#
-# The eclass tests for working fortran compilers
-# and exports the variables FC and F77.
-# Optionally, it checks for extended capabilities based on
-# the variable options selected in the ebuild
-# The only phase function exported is fortran-2_pkg_setup.
-# @EXAMPLE:
-# FORTRAN_NEEDED="lapack fortran"
-#
-# inherit fortran-2
-#
-# FORTRAN_NEED_OPENMP=1
-

-# Set to "1" in order to automatically have the eclass abort if the fortran
-# compiler lacks openmp support.

-# @DESCRIPTION:
-# If your package has an optional fortran support, set this variable

-# dependency.
-#
-# e.g. FORTRAN_NEEDED=lapack would result in
-#
-# DEPEND="lapack? ( virtual/fortran )"
-#
-# If unset, we always depend on virtual/fortran.
