# 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. |
