# This ebuild is made splitting the suggested start_cern script provided
# as ${HOMEPAGE}/cernlib/install/start_cern
#
# Currently an error is presented by strip trying to strip a script (bin/paw).
#
# Use flags:
# - symlink : creates /opt/cern/current symbolic link to current CERN libraries
# - sources : they are installed in /opt/cern/$VERSION/src if required
#
# Updating and next versions:
# If a newer version of CERNLIB will ever be published, it should be sufficient
# to change the ebuild name to reflect the new year version; all patches in
# files directory with the name starting with the year are applies in no defined
# order (in src_unpack()).
#
# Note: version 2005 requires about 350 MB of free space in portage build
# directory.
#
# Known bugs:
# -	minuit32, mathlib32, gcalor are not supported
# -	it seems to work, but uses the linux.cf provided, which is not optimal
#

# CERNLIB requires imake (in Gentoo's x11 package), GNU make, a C preprocessor

# I'm currently assuming that any sane (Gentoo) distriibution has all of them
# by default, except for imake .
