# This is a simple script which is meant to help developers
|
|
# better deal with the GNU autotools, specifically:
|
|
#
|
|
# aclocal
|
|
# libtoolize
|
|
# autoconf
|
|
# autoheader
|
|
# automake
|
|
#
|
|
# The whole thing is quite complex...
|
|
#
|
|
# The idea is to run this collection of tools on a single platform,
|
|
# typically the main development platform, running a recent version of
|
|
# autoconf. In theory, if we had these tools on each platform where we
|
|
# ever expected to port the software, we would never need to checkin
|
|
# more than a few autotools configuration files. However, the whole
|
|
# idea is to generate a configure script and associated files in a way
|
|
# that is portable across platforms, so we *have* to check in a whole
|
|
# bunch of files generated by all these tools.
|
|
|
|
# The real source files are:
|
|
#
|
|
# acinclude.m4 (used by aclocal)
|
|
# configure.ac (main autoconf file)
|
|
# Makefile.am, */Makefile.am (automake config files)
|
|
#
|
|
# All the rest is auto-generated.
