# This script is based on the one written for xf86-video-unichrome by
|
||||
# Luc Verhaegen, but was rewritten almost completely by Hans Ulrich
|
||||
# Niedermann. The script contains a few bug fixes from Egbert Eich,
|
||||
# Matthias Hopf, Joerg Sonnenberger, and possibly others.
|
||||
#
|
||||
# The author thanks the nice people on #git for the assistance.
|
||||
#
|
||||
# Simple testing of this script:
|
||||
# /sbin/busybox sh git_version.sh --example > moo.c \
|
||||
# && gcc -Wall -Wextra -Wno-unused -o moo moo.c \
|
||||
# && ./moo
|
||||
# (bash should also do)
|
||||
#
|
||||
# For how to hook this up to your automake- and/or imake-based build
|
||||
# system, best take a look at how the RadeonHD.am and/or RadeonHD.tmpl
|
||||
# work in the xf86-video-radeonhd build system. For non-recursive make,
|
||||
# you can probably make things a little bit simpler.
|
||||
#
|
||||
# Requires git >= 1.3.0 for the 'git foo' (with space) syntax,
|

# and git >= 1.4 for some specific commands.
