# @BLURB: Eclass for writing KDE "live" ebuilds.
# @DESCRIPTION:
# This eclass provides all functions to handle live KDE ebuilds,
# monolithic, split and extragear ebuilds.
#
# The eclass checks out to ${DISTDIR}/svn-src/KDE, and recreates the structure
# of upstream's SVN repository locally.

# @ECLASS-VARIABLE: NEED_KDE
# @DESCRIPTION:
# Defaults to "svn", also see: gks-base.eclass.

	NEED_KDE="svn"
fi

# @ECLASS-VARIABLE: NEED_KDE_PRE
# @DESCRIPTION:
# This variable tells the eclass to set NEED_KDE and SLOT based on the PV of the
# ebuild.
#
# Acceptable values for the PV when using this are:
#   - ${PV}_pre4    - Compile against the kde-4 SLOT
#   - ${PV}_pre9999 - Compile against the kde-svn SLOT

		9999) SLOT="kde-svn"; NEED_KDE="svn";;
		*) die "Unknown package version." ;;

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

# @ECLASS-VARIABLE: KMMODULE
# @DESCRIPTION:
# Specify exactly one subdirectory of $KMNAME here. Defaults to $PN.
# You shouldn't set this for monolithic ebuilds.
