# @ECLASS-VARIABLE: DOCS
# @DESCRIPTION:
# This variable holds an array of relative paths of files to be dodoc-ed.
# By default, it contains the standard list of autotools doc files.
# Because clutter declares it as a non-array by default, we adapt it here;
# this way, if other -multilib eclasses (most of which use an array for DOCS)
# are involved at the ebuild level, the right thing is more likely to happen

# since the variable is eval-ed before substitution. Empty by default.
