# @BLURB: Eclass for writing "split" KDE packages.
# @DESCRIPTION:
# This eclass provides all necessary functions for writing split KDE ebuilds.
#
# You must define KMNAME to use this eclass, and do so before inheriting it. All other variables are optional.
# Do not include the same item in more than one of KMMODULE, KMMEXTRA, KMCOMPILEONLY, KMEXTRACTONLY.
#
# NOTE: This eclass uses the SLOT dependencies from EAPI="1" or compatible,
# hence you must define EAPI="1" in the ebuild, before inheriting any eclasses.

# @ECLASS-VARIABLE: KMNAME
# @DESCRIPTION:
# Name of the parent-module (e.g. kdebase, kdepim, ...). You _must_ set it _before_ inheriting this eclass,
# (unlike the other parameters), since it's used to set $SRC_URI.

# @ECLASS-VARIABLE: KMMODULE
# @DESCRIPTION:
# Specify exactly one subdirectory of $KMNAME here. Defaults to $PN.
# The subdirectory listed here is treated exactly like items in $KMEXTRA.
#
# Example: The ebuild name of "kdebase/l10n" is kde-base/kdebase-l10n, because
# just 'l10n' would be too confusing. Hence it sets KMMODULE="l10n".

# @ECLASS-VARIABLE: KMNOMODULE
# @DESCRIPTION:
# If set to "true", $KMMODULE doesn't have to be defined.
#
# Example usage: If you're installing subdirectories of a package, like plugins,
# you mark the topsubdirectory (containing the package) as $KMEXTRACTONLY, and set KMNOMODULE="true".
if [[ ${KMNOMODULE} != "true" && -z ${KMMODULE} ]]; then

fi

# @ECLASS-VARIABLE: KMEXTRA
# @DESCRIPTION:
# All subdirectories listed here will be extracted, compiled & installed.
# $KMMODULE is always added to $KMEXTRA.
# If the htmlhandbook USE-flag is set, and if this directory exists,
# then "doc/$KMMODULE" is added to $KMEXTRA. In other cases, this should be
# handled in the ebuild.
# If the documentation is in a different subdirectory, you should add it to KMEXTRA.

# @ECLASS-VARIABLE: KMCOMPILEONLY
# @DESCRIPTION:
# All subdirectories listed here will be extracted & compiled, but not installed.

# @ECLASS-VARIABLE: KMEXTRACTONLY
# @DESCRIPTION:
# All subdirectories listed here will be extracted, but not compiled nor installed.
# This can be used to avoid compilation in a subdirectory of a directory in $KMMODULE or $KMEXTRA

# @ECLASS-VARIABLE: KMTARPARAMS
# @DESCRIPTION:
# Specify extra parameters to pass to tar, in kde4-meta_src_extract.
# '-xpf -j' are passed to tar by default.

# @FUNCTION: kde4-meta_pkg_setup

# Currently just calls its equivalent in kde4-base.eclass(5). Use this in split
