# @BLURB: Simplify libretro core ebuilds
|
||||
# @DESCRIPTION:
|
||||
# The libretro eclass is designed to streamline the construction of
|
||||
# ebuilds for Libretro core ebuilds.
|
||||
#
|
||||
# Libretro cores can be found under https://github.com/libretro/
|
||||
#
|
||||
# They all use the same basic make based build system, are located
|
||||
# in the same github account, and do not release named or numbered
|
||||
# versions (so ebuild versions for git commits are keys).
|
||||
# This eclass covers those commonalities reducing much duplication
|
||||
# between the ebuilds.
|
||||
# @EXAMPLE:
|
||||
# @CODE
|
||||
# EAPI=7
|
||||
#
|
||||
# LIBRETRO_CORE_NAME="2048"
|
||||
# LIBRETRO_COMMIT_SHA="45655d3662e4cbcd8afb28e2ee3f5494a75888de"
|
||||
# KEYWORDS="~amd64 ~x86"
|
||||
# inherit libretro-core
|
||||
#
|
||||
# DESCRIPTION="Port of 2048 puzzle game to the libretro API"
