#
|
|
# This Makefile fragment handles Emacs Lisp Packages (== ELPs).
|
|
#
|
|
# Note to users:
|
|
#
|
|
# * Users choose one favourite Emacs version.
|
|
#
|
|
# * Emacs Lisp files are installed...
|
|
# GNU emacs
|
|
# -> ${PREFIX}/share/emacs/site-lisp/foo/...
|
|
# XEmacs
|
|
# ->${PREFIX}/lib/xemacs/site-packages/lisp/foo/...
|
|
#
|
|
# * You can't install an ELP for both Emacs and XEmacs
|
|
# simultaneously.
|
|
#
|
|
# * XEmacs package's names are prefix'ed by "xemacs-".
|
|
#
|
|
# Note to package developers:
|
|
#
|
|
# * XEmacs package's names are prefix'ed by "xemacs-".
|
|
#
|
|
# This is to make sure ELPs for XEmacs keep their own dependency
|
|
# tree (for example, if an ELP "bar" depends on another ELP "foo",
|
|
# "xemacs-bar" depends on "xemacs-foo". "foo" (installed for GNU
|
|
# Emacs) is useless for "xemacs-bar" in this case.).
|
|
#
|
|
# Make sure too that "foo" and "xemacs-foo" conflict each other,
|
|
# since they can share some files. (Making all ELPs separately
|
|
# installable for GNU Emacs/XEmacs might be possible.)
|
|
#
|
|
# * Assume each ELP supports all Emacs versions by default. If the
|
|
# ELP supports only certain Emacs versions, define EMACS_VERSIONS
|
|
# _ACCEPTED explicitly before including mk/emacs.mk.

|
|
#
