# TODO FIX ends

# The following code adds support for broken-up kde-base-derived ebuilds, e.g. a separate
# kmail ebuild that still uses the big kdepim tarball. KM is short for 'kde meta'.
# Set the following variables in the ebuild. Only KMNAME must be set, the rest are optional.
# A directory or file can be a path with any number of components (eg foo/bar/baz.h). 
# Do not include the same item in more than one of KMMODULE, KMMEXTRA, KMCOMPILEONLY, KMEXTRACTONLY, KMCOPYLIB.
#
# KMNAME: name of the metapackage (eg kdebase, kdepim). Must be set before inheriting this eclass
# (unlike the other parameters here), since it affects $SRC_URI.
# KMNOMODULE: 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.
# KMMODULE: Defaults to $PN. Specify one subdirectory of KMNAME. Is treated exactly like items in KMEXTRA.
# Fex., the ebuild name of kdebase/l10n is kdebase-l10n, because just 'l10n' would be too confusing.
# KMNODOCS: unless set to "true", 'doc/$KMMODULE' is added to KMEXTRA. Set for packages that don't have docs.
# KMEXTRA, KMCOMPILEONLY, KMEXTRACTONLY: 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 the three variables.
# - 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.
#
# KMCOPYLIB: 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*.
