Branch: MAIN
Changes since 1.18: +32 -12 lines
elisp.eclass:
* Depend on Emacs by NEED_EMACS=<version> before inherit
* DOCS variable is used in src_install() to give a number of
documentation files
* Documented some missing parts
* Some code clean-up

elisp-common:
* elisp-emacs-version() to determine Emacs' current major
version number
* site-gentoo.el is only regenerated if there was actually a change,
thus preventing unecessary output on postrm or postinst
* now every action is commented with an einfo output
* Documented some missing parts
* Some code clean-up

10 # This eclass sets the site-lisp directory for emacs-related packages.
11 #
12 # Emacs support for other than pure elisp packages is handled by
13 # elisp-common.eclass where you won't have a dependency on Emacs
14 # itself. All elisp-* functions are documented there.
15 #
16 # Setting SIMPLE_ELISP=t in an ebuild means, that the package's source
17 # is a single (in whatever way) compressed elisp file with the file name
18 # ${PN}-${PV}. The consequences:
19 #
20 # 1.) ${S} is redefined
21 # 2.) ${PN}-${PV}.el is moved to ${PN} in the system.
22 #
23 # SRC_URI should be set to wherever the primary app-emacs/ maintainer
24 # keeps the local elisp mirror, since most app-emacs packages are
25 # upstream as a single .el file.
26 #
27 # DOCS="blah.txt ChangeLog" is automatically used to install the given
28 # files by dodoc in src_install().
29 #
30 # If you need anything different from Emacs 21, use the NEED_EMACS
31 # variable before inheriting elisp.eclass. Set it to the major version
32 # your package uses and the dependency will be adjusted.
