To be used by X.Org packages with a meson build system. Largely a copy
of xorg-3.eclass with changes necessary to switch from autotools to
meson.
Compared with xorg-3, I've dropped a few things that I don't think are
necessary (at least initially), namely:
- font support (media-libs/font-* packages); packages change very
rarely and don't have meson build systems upstream.
- XORG_DOC dependencies. This actually looks wrong in xorg-3?
- asciidoc is used to generate docbook documentation (which I
don't think we ever do in the ebuilds)
- xmlto is used to create some man pages from XML, but the man pages
are checked into git so we don't ever need to generate them

# This eclass makes trivial X ebuilds possible for apps, drivers,
|
|
# and more. Many things that would normally be done in various functions
|
|
# can be accessed by setting variables instead, such as patching,
|
|
# passing options to meson and installing docs.
|
|
#
|
|
# All you need to do in a basic ebuild is inherit this eclass and set
|
|
# DESCRIPTION, KEYWORDS and RDEPEND/DEPEND. If your package is hosted
|
|
# with the other X packages, you don't need to set SRC_URI. Pretty much
|
|
# everything else should be automatic.
