# This eclass handles vim, gvim and vim-core.  Support for -cvs ebuilds is
# included in the eclass, since it's rather easy to do, but there are no
# official vim*-cvs ebuilds in the tree.

# gvim's GUI preference order is as follows:
# aqua                          CARBON (not tested)
# -aqua gtk gnome               GNOME2
# -aqua gtk -gnome              GTK2
# -aqua -gtk  motif             MOTIF
# -aqua -gtk -motif nextaw      NEXTAW
# -aqua -gtk -motif -nextaw     ATHENA

# Support -cvs ebuilds, even though they're not in the official tree.
