# @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 top subdirectory (containing the package) as $KMEXTRACTONLY, and
# set KMNOMODULE="true".

fi

# @ECLASS-VARIABLE: KMEXTRA
# @DESCRIPTION:
# All subdirectories listed here will be extracted, compiled & installed.
# $KMMODULE is always added to $KMEXTRA.
# If KDE_HANDBOOK is 'always' or 'optional' and handbook USE-flag is set, and if this
# directory exists, then "doc/$KMMODULE" is added to $KMEXTRA. If there's additional
# documentation in different subdirectories, it should be added to KMEXTRA manually..

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

# TODO: better formulation may be needed
# @ECLASS-VARIABLE: KMEXTRACTONLY
# @DESCRIPTION:
# All subdirectories listed here will be extracted, but neither 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.
