# @ECLASS-VARIABLE: KMNAME
# @DESCRIPTION:
# Name of the metapackage (eg kdebase, kdepim). Must be set before inheriting
# this eclass, since it affects $SRC_URI. This variable MUST be set.

# @ECLASS-VARIABLE: KMNOMODULE
# @DESCRIPTION:
# Unless set to "true", then KMMODULE will be not defined and so also the docs.
# Useful when we want to installs subdirs of a subproject, like plugins, and we
# have to mark the topsubdir ad KMEXTRACTONLY.

# @ECLASS-VARIABLE: KMMODULE
# @DESCRIPTION:
# Defaults to $PN. Specify one subdirectory of KMNAME. Is treated exactly like items in KMEXTRA.
# Fex., the ebuild name of kdebase/l10n is kdebase-l10n, because just 'l10n' would be too confusing.
# Do not include the same item in more than one of KMMODULE, KMMEXTRA, KMCOMPILEONLY, KMEXTRACTONLY, KMCOPYLIB.

# @ECLASS-VARIABLE: KMNODOCS
# @DESCRIPTION:
# Unless set to "true", 'doc/$KMMODULE' is added to KMEXTRA. Set for packages that don't have docs.

# @ECLASS-VARIABLE: KMEXTRA
# @DESCRIPTION:
# Specify files/dirs to extract, compile and install. $KMMODULE is added to
# KMEXTRA automatically. So is doc/$KMMODULE (unless $KMNODOCS==true). Makefiles
# are created automagically to compile/install the correct files. Observe these
# rules:
#
# - Don't specify the same file in more than one of three variables (KMEXTRA,
# KMCOMPILEONLY, and KMEXTRACTONLY)
# - When using KMEXTRA, remember to add the doc/foo dir for the extra dirs if one exists.
# - KMEXTRACTONLY take effect over an entire directory tree, you can override it defining
#
# KMEXTRA, KMCOMPILEONLY for every subdir that must have a different behavior.
# eg. you have this tree:
# foo/bar
# foo/bar/baz1
# foo/bar/baz1/taz
# foo/bar/baz2
# If you define:
# KMEXTRACTONLY=foo/bar and KMEXTRA=foo/bar/baz1
# then the only directory compiled will be foo/bar/baz1 and not foo/bar/baz1/taz (also if it's a subdir of a KMEXTRA) or foo/bar/baz2
#
# IMPORTANT!!! you can't define a KMCOMPILEONLY SUBDIR if its parents are defined as KMEXTRA or KMMODULE. or it will be installed anywhere. To avoid this probably are needed some chenges to the generated Makefile.in.
# Do not include the same item in more than one of KMMODULE, KMMEXTRA, KMCOMPILEONLY, KMEXTRACTONLY, KMCOPYLIB.

# @ECLASS-VARIABLE: KMCOMPILEONLY
# @DESCRIPTION:
# Please see KMEXTRA

# @ECLASS-VARIABLE: KMEXTRACTONLY
# @DESCRIPTION:
# Please see KMEXTRA

# @ECLASS-VARIABLE: KMCOPYLIB
# @DESCRIPTION:
# Contains an even number of $IFS (i.e. whitespace) -separated words.
# Each two consecutive words, libname and dirname, are considered. symlinks are created under $S/$dirname
# pointing to $PREFIX/lib/libname*.
# Do not include the same item in more than one of KMMODULE, KMMEXTRA, KMCOMPILEONLY, KMEXTRACTONLY, KMCOPYLIB.
