-# @ECLASS-VARIABLE: EGIT_CLONE_TYPE
-# @DESCRIPTION:
-# Type of clone that should be used against the remote repository.
-# This can be either of: 'mirror', 'single', 'shallow'.
-#
-# This is intended to be set by user in make.conf. Ebuilds are supposed
-# to set EGIT_MIN_CLONE_TYPE if necessary instead.
-#
-# The 'mirror' type clones all remote branches and tags with complete
-# history and all notes. EGIT_COMMIT can specify any commit hash.
-# Upstream-removed branches and tags are purged from the local clone
-# while fetching. This mode is suitable for cloning the local copy
-# for development or hosting a local git mirror. However, clones
-# of repositories with large diverged branches may quickly grow large.
-#
-# The 'single+tags' type clones the requested branch and all tags
-# in the repository. All notes are fetched as well. EGIT_COMMIT
-# can safely specify hashes throughout the current branch and all tags.
-# No purging of old references is done (if you often switch branches,
-# you may need to remove stale branches yourself). This mode is intended
-# mostly for use with broken git servers such as Google Code that fail
-# to fetch tags along with the branch in 'single' mode.
-#
-# The 'single' type clones only the requested branch or tag. Tags
-# referencing commits throughout the branch history are fetched as well,
-# and all notes. EGIT_COMMIT can safely specify only hashes
-# in the current branch. No purging of old references is done (if you
-# often switch branches, you may need to remove stale branches
-# yourself). This mode is suitable for general use.
-#
-# The 'shallow' type clones only the newest commit on requested branch
-# or tag. EGIT_COMMIT can only specify tags, and since the history is
-# unavailable calls like 'git describe' will not reference prior tags.
-# No purging of old references is done. This mode is intended mostly for
-# embedded systems with limited disk space.
-: ${EGIT_CLONE_TYPE:=single}
-
-# @ECLASS-VARIABLE: EGIT_MIN_CLONE_TYPE
-# @DESCRIPTION:
-# 'Minimum' clone type supported by the ebuild. Takes same values
-# as EGIT_CLONE_TYPE. When user sets a type that's 'lower' (that is,
-# later on the list) than EGIT_MIN_CLONE_TYPE, the eclass uses
-# EGIT_MIN_CLONE_TYPE instead.
-#
-# This variable is intended to be used by ebuilds only. Users are
-# supposed to set EGIT_CLONE_TYPE instead.
-#
-# A common case is to use 'single' whenever the build system requires
-# access to full branch history, or 'single+tags' when Google Code
-# or a similar remote is used that does not support shallow clones
-# and fetching tags along with commits. Please use sparingly, and to fix
-# fatal errors rather than 'non-pretty versions'.
-: ${EGIT_MIN_CLONE_TYPE:=shallow}
-
-# @ECLASS-VARIABLE: EGIT3_STORE_DIR
-# @DESCRIPTION:
-# Storage directory for git sources.
-#
-# This is intended to be set by user in make.conf. Ebuilds must not set
-# it.
-#
-# EGIT3_STORE_DIR=${DISTDIR}/git3-src
-
-# @ECLASS-VARIABLE: EGIT_MIRROR_URI
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# 'Top' URI to a local git mirror. If specified, the eclass will try
-# to fetch from the local mirror instead of using the remote repository.
-#
-# The mirror needs to follow EGIT3_STORE_DIR structure. The directory
-# created by eclass can be used for that purpose.
-#
-# Example:
-# @CODE
-# EGIT_MIRROR_URI="git://mirror.lan/"
-# @CODE
-
-# @ECLASS-VARIABLE: EGIT_REPO_URI
-# @REQUIRED
-# @DESCRIPTION:
-# URIs to the repository, e.g. https://foo. If multiple URIs are
-# provided, the eclass will consider the remaining URIs as fallbacks
-# to try if the first URI does not work. For supported URI syntaxes,
-# read the manpage for git-clone(1).
-#
-# URIs should be using https:// whenever possible. http:// and git://
-# URIs are completely unsecured and their use (even if only as
-# a fallback) renders the ebuild completely vulnerable to MITM attacks.
-#
-# It can be overridden via env using ${PN}_LIVE_REPO variable.
-#
-# Can be a whitespace-separated list or an array.
-#
-# Example:
-# @CODE
-# EGIT_REPO_URI="https://a/b.git https://c/d.git";
-# @CODE
-
-# @ECLASS-VARIABLE: EVCS_OFFLINE
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# If non-empty, this variable prevents any online operations.
-
-# @ECLASS-VARIABLE: EVCS_UMASK
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# Set this variable to a custom umask. This is intended to be set by
-# users. By setting this to something like 002, it can make life easier
-# for people who do development as non-root (but are in the portage
-# group), and then switch over to building with FEATURES=userpriv.
-# Or vice-versa. Shouldn't be a security issue here as anyone who has
-# portage group write access already can screw the system over in more
-# creative ways.
-
-# @ECLASS-VARIABLE: EGIT_BRANCH
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# The branch name to check out. If unset, the upstream default (HEAD)
-# will be used.
-#
-# It can be overriden via env using ${PN}_LIVE_BRANCH variable.
-
-# @ECLASS-VARIABLE: EGIT_COMMIT
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# The tag name or commit identifier to check out. If unset, newest
-# commit from the branch will be used. Note that if set to a commit
-# not on HEAD branch, EGIT_BRANCH needs to be set to a branch on which
-# the commit is available.
-#
-# It can be overriden via env using ${PN}_LIVE_COMMIT variable.
-
-# @ECLASS-VARIABLE: EGIT_COMMIT_DATE
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# Attempt to check out the repository state for the specified timestamp.
-# The date should be in format understood by 'git rev-list'. The commits
-# on EGIT_BRANCH will be considered.
-#
-# The eclass will select the last commit with commit date preceding
-# the specified date. When merge commits are found, only first parents
-# will be considered in order to avoid switching into external branches
-# (assuming that merges are done correctly). In other words, each merge
-# will be considered alike a single commit with date corresponding
-# to the merge commit date.
-#
-# It can be overriden via env using ${PN}_LIVE_COMMIT_DATE variable.
-
-# @ECLASS-VARIABLE: EGIT_CHECKOUT_DIR
-# @DESCRIPTION:
-# The directory to check the git sources out to.
-#
-# EGIT_CHECKOUT_DIR=${WORKDIR}/${P}
-
-# @ECLASS-VARIABLE: EGIT_SUBMODULES
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# An array of inclusive and exclusive wildcards on submodule names,
-# stating which submodules are fetched and checked out. Exclusions
-# start with '-', and exclude previously matched submodules.
-#
-# If unset, all submodules are enabled. Empty list disables all
-# submodules. In order to use an exclude-only list, start the array
-# with '*'.
-#
-# Remember that wildcards need to be quoted in order to prevent filename
-# expansion.
-#
-# Examples:
-# @CODE
-# # Disable all submodules
-# EGIT_SUBMODULES=()
-#
-# # Include only foo and bar
-# EGIT_SUBMODULES=( foo bar )
-#
-# # Use all submodules except for test-* but include test-lib
-# EGIT_SUBMODULES=( '*' '-test-*' test-lib )
-# @CODE
