		8	# @BLURB: many extra (but common) functions that are used in ebuilds
		9	# @DESCRIPTION:
		10	# The eutils eclass contains a suite of functions that complement
		11	# the ones that ebuild.sh already contain. The idea is that the functions
		12	# are not required in all ebuilds but enough utilize them to have a common
		13	# home rather than having multiple ebuilds implementing the same thing.
4	#	14	#
5	# This eclass is for general purpose functions that most ebuilds	15	# Due to the nature of this eclass, some functions may have maintainers
6	# have to implement themselves.	16	# different from the overall eclass!

8	# NB: If you add anything, please comment it!
