17     # dependencies shall use the USE dependency string in ${MULTILIB_USEDEP}
18     # to properly request multilib enabled.

52     # List of multilib ABIs supported by the ebuild. If unset, defaults to

55     # This variable is intended for use in prebuilt multilib packages that
56     # can provide binaries only for a limited set of ABIs. If ABIs need to
57     # be limited due to a bug in source code, package.use.mask is
58     # recommended instead.
59     #
60     # Example use:
61     # @CODE

69     # to support multilib as well.
70     #
71     # Example use:
72     # @CODE

74     # net-libs/libbar[ssl,${MULTILIB_USEDEP}]"

293     # @DESCRIPTION:
294     # A list of headers to wrap for multilib support. The listed headers
295     # will be moved to a non-standard location and replaced with a file
296     # including them conditionally to current ABI.
297     #
298     # This variable has to be a bash array. Paths shall be relative to
299     # installation root (${ED}), and name regular files. Recursive wrapping
300     # is not supported.
301     #
302     # Please note that header wrapping is *discouraged*. It is preferred to
303     # install all headers in a subdirectory of libdir and use pkg-config to
304     # locate the headers. Some C preprocessors will not work with wrapped
305     # headers.
306     #
307     # Example:
308     # @CODE
309     # MULTILIB_WRAPPED_HEADERS=(
310     # /usr/include/foobar/config.h
311     # )
312     # @CODE

317     # The listed executables will be renamed to ${CHOST}-${basename},
318     # and the native variant will be symlinked to the generic name.
319     #
320     # This variable has to be a bash array. Paths shall be relative to
321 mgorny 1.29 # installation root (${ED}), and name regular files or symbolic
322     # links to regular files. Recursive wrapping is not supported.
323     #
324     # If symbolic link is passed, both symlink path and symlink target
325     # will be changed. As a result, the symlink target is expected
326     # to be wrapped as well (either by listing in MULTILIB_CHOST_TOOLS
327     # or externally).
328 mgorny 1.26 #
329     # Please note that tool wrapping is *discouraged*. It is preferred to

332     #
333     # Packages that search for tools properly (e.g. using AC_PATH_TOOL
334     # macro) will find the wrapper executables automatically. Other packages
335     # will need explicit override of tool paths.

337     # Example:
338     # @CODE
