5 # This eclass is used by vim.eclass and vim-plugin.eclass to update
6 # the documentation tags. This is necessary since vim doesn't look in
7 # /usr/share/vim/vimfiles/doc for documentation; it only uses the
8 # versioned directory, for example /usr/share/vim/vim62/doc
9 #
10 # We depend on vim being installed, which is satisfied by either the
11 # DEPEND in vim-plugin or by whatever version of vim is being
12 # installed by the eclass.
