# @BLURB: Eclass for Emacs Lisp packages
|
| 15 |
# @DESCRIPTION:
|
| 16 |
#
|
| 17 |
# This eclass sets the site-lisp directory for Emacs-related packages.
|
| 18 |
#
|
| 19 |
# Emacs support for other than pure elisp packages is handled by
|
| 20 |
# elisp-common.eclass where you won't have a dependency on Emacs itself.
|
| 21 |
# All elisp-* functions are documented there.
|
| 22 |
#
|
| 23 |
# If the package's source is a single (in whatever way) compressed elisp
|
| 24 |
# file with the file name ${P}.el, then this eclass will move ${P}.el to
|
| 25 |
# ${PN}.el in src_unpack().
|
| 26 |
|
| 27 |
# @ECLASS-VARIABLE: DOCS
|
| 28 |
# @DESCRIPTION:
|
| 29 |
# DOCS="blah.txt ChangeLog" is automatically used to install the given
|
| 30 |
# files by dodoc in src_install().
|
| 31 |
|
| 32 |
# @ECLASS-VARIABLE: NEED_EMACS
|
| 33 |
# @DESCRIPTION:
|
| 34 |
# If you need anything different from Emacs 21, use the NEED_EMACS
|
| 35 |
# variable before inheriting elisp.eclass. Set it to the major version
|
| 36 |
# your package uses and the dependency will be adjusted.
