# @BLURB: many extra (but common) functions that are used in ebuilds
|
|
|
|
|
# @DESCRIPTION:
|
|
|
|
|
# The eutils eclass contains a suite of functions that complement
|
|
|
|
|
# the ones that ebuild.sh already contain. The idea is that the functions
|
|
|
|
|
# are not required in all ebuilds but enough utilize them to have a common
|
|
|
|
|
# home rather than having multiple ebuilds implementing the same thing.
|
|
|
|
|
#
|
|
|
|
|
# Due to the nature of this eclass, some functions may have maintainers
|
|
|
|
|
# different from the overall eclass!
|
|
|
|
|
#
|
|
|
|
|
# This eclass is DEPRECATED and must not be inherited by any new ebuilds
|
|
|
|
|
# or eclasses. Use the more specific split eclasses instead, or native
|
|
|
|
|
# package manager functions when available.
