# @SUPPORTED_EAPIS: 7
# @BLURB: Eclass used to create and maintain a single group entry
# @DESCRIPTION:
# This eclass represents and creates a single group entry. The name
# of the group is derived from ${PN}, while (preferred) GID needs to
# be specified via ACCT_GROUP_ID. Packages (and users) needing the group
# in question should depend on the package providing it.
#
# Example:
# If your package needs group 'foo', you create 'acct-group/foo' package
# and add an ebuild with the following contents:
#
# @CODE
# EAPI=7
# inherit acct-group
# ACCT_GROUP_ID=200
# @CODE
#
# Then you add appropriate dependency to your package. The dependency
# type(s) should be:
# - DEPEND (+ RDEPEND) if the group is already needed at build time,
# - RDEPEND if it is needed at install time (e.g. you 'fowners' files
# in pkg_preinst) or run time.

# @DESCRIPTION:
# Preferred GID for the new group. This variable is obligatory, and its
# value must be unique across all group packages.
#
# Overlays should set this to -1 to dynamically allocate GID. Using -1
# in ::gentoo is prohibited by policy.
# @ECLASS-VARIABLE: ACCT_GROUP_ENFORCE_ID
# @DESCRIPTION:
# If set to a non-null value, the eclass will require the group to have
# specified GID. If the group already exists with another GID, or
# the GID is taken by another group, the install will fail.
