# 1. Depend on the right emacs using ${EMACS_TYPE}. We don't have to
# (and in fact shouldn't) depend on the exact version, just *a*
# version. Do *not* include modules.mk as that will get us a tighter
# pattern than we want, as well as other problematic effects.
#
# XXX: it would be better to split modules.mk and share the logic
# that can be shared.

# 2. Now it gets gross. Before this meta-package was introduced, the
# emacs packages all had PKGNAME set to "emacs". Now the meta-package
# is called "emacs" and the emacs packages themselves have the emacs
# major version in them. But in order to make updates work properly,
# the version of the package called "emacs" cannot go down. We need to
# set MY_EMACS_VERSION accordingly. The following were the versions at
# the time the renaming was done:
#   emacs20		20.7nb16
#   emacs21		21.4anb26
#   emacs21-nox11	21.4anb13
#   emacs22		22.3nb26
#   emacs22-nox11	22.3nb3
#   emacs23		23.4nb12
#   emacs23-nox11	23.4nb1
#   emacs24		24.2nb6
#   emacs24-nox11	24.2
#   emacs25+		n/a
#
# Set VER to the version from the above table, and REV to the
# PKGREVISION value.
