# @BLURB: Simplify installation of SWORD modules
# @DESCRIPTION:
# This eclass provides dependencies, ebuild environment and the src_install
# function common to all app-text/sword modules published by the SWORD Project.
#
# Note that as of 2021-06-16 module archives published by SWORD are still
# not versioned and it is necessary to look at respective module pages in
# order to see what versions the currently available files are. Once
# a module file has been replicated to the Gentoo mirror network it will be
# versioned and remain available even after upstream has changed their
# version, however users not using mirrors will encounter hash conflicts
# on updated modules. Should that happen, please notify the relevant
# package maintainers that a new version is available.
#
# @EXAMPLE:
# sword-Personal-1.0.ebuild, a typical ebuild using sword-module.eclass:
#
# @CODE
# EAPI=8
#
# SWORD_MINIMUM_VERSION="1.5.1a"
#
# inherit sword-module
#
# DESCRIPTION="SWORD module for storing one's own commentary"
# HOMEPAGE="https://crosswire.org/sword/modules/ModInfo.jsp?modName=Personal"
# LICENSE="public-domain"
# KEYWORDS="~amd64 ~ppc ~x86"

# @ECLASS-VARIABLE: SWORD_MINIMUM_VERSION
# @DEFAULT_UNSET
# @PRE_INHERIT
# @DESCRIPTION:
# If set to a non-null value, specifies the minimum version of app-text/sword
# the module requires. This will be included in RDEPEND. If null or unset,
# the dependency will be unversioned.
# Needs to be set before the inherit line.

# @PRE_INHERIT
# @DESCRIPTION:
# Case-sensitive name of the SWORD-Project module to install. If unset
# or null, use the name produced by removing the prefix 'sword-' from PN.
# Needs to be set before the inherit line.
