# @DESCRIPTION: # @DEPRECATED: native package manager functions, more specific eclasses
# The eutils eclass contains a suite of functions that complement
# the ones that ebuild.sh already contain. The idea is that the functions
# are not required in all ebuilds but enough utilize them to have a common
# home rather than having multiple ebuilds implementing the same thing.
#
# Due to the nature of this eclass, some functions may have maintainers
# different from the overall eclass!
#
# This eclass is DEPRECATED and must not be inherited by any new ebuilds
# or eclasses. Use the more specific split eclasses instead, or native
# package manager functions when available.

# @FUNCTION: einstalldocs
# @DESCRIPTION:
# Install documentation using DOCS and HTML_DOCS, in EAPIs that do not
# provide this function. When available (i.e., in EAPI 6 or later),
# the package manager implementation should be used instead.
#
# If DOCS is declared and non-empty, all files listed in it are
# installed. The files must exist, otherwise the function will fail.
# In EAPI 4 and 5, DOCS may specify directories as well; in earlier
# EAPIs using directories is unsupported.
#
# If DOCS is not declared, the files matching patterns given
# in the default EAPI implementation of src_install will be installed.
# If this is undesired, DOCS can be set to empty value to prevent any
# documentation from being installed.
#
# If HTML_DOCS is declared and non-empty, all files and/or directories
# listed in it are installed as HTML docs (using dohtml).
#
# Both DOCS and HTML_DOCS can either be an array or a whitespace-
# separated list. Whenever directories are allowed, '<directory>/.' may
# be specified in order to install all files within the directory
# without creating a sub-directory in docdir.
#
# Passing additional options to dodoc and dohtml is not supported.
# If you needed such a thing, you need to call those helpers explicitly.
