# @BLURB: Common code for GitHub-hosted packages
# @DESCRIPTION:
# The github-pkg eclass fills in git-r3 related variables with sensible defaults.
# By default, HOMEPAGE is set to the repo URL and EGIT_REPO_URI is derived from it.
# Upstreams tend to use wildly inconsistent tarball naming conventions, so no SRC_URI is provided.
# @SUPPORTED_EAPIS: 7 8

# @ECLASS_VARIABLE: GITHUB_USER
# @PRE_INHERIT
# @DEFAULT_UNSET
# @DESCRIPTION:
# Specify the owner name in the repository's URL; defaults to PN.

# @ECLASS_VARIABLE: GITHUB_PROJ
# @PRE_INHERIT
# @DEFAULT_UNSET
# @DESCRIPTION:
# Specify the project name in the repository's URL; defaults to PN.

# @ECLASS_VARIABLE: GITHUB_HOMEPAGE
# @OUTPUT_VARIABLE
# @DESCRIPTION:
# Computed path to the git repository; also used to set EGIT_REPO_URI if package version is 9999.
