autoconf/bin/autoconf.in
Akim Demaille 6acd8f5313 * lib/autom4te.in: New.
* lib/Makefile.am (edit, autom4te.cfg): New.
* bin/autom4te.in (BEGIN): Simplify.
Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
(&load_configuration): New.  Use it.
(&parse_args): Support --mode, --set, and --melt.
* bin/autoconf.in: Simplify and adjust.
* tests/Makefile.am (AUTOMAKE): Use --set.
* tests/atlocal.in: Adjust.
* BUGS: distcheck and check are weak.

Usage: $0 [OPTION] ... [TEMPLATE-FILE]
Generate a configuration script from a TEMPLATE-FILE if given, or
\`configure.ac' if present, or else \`configure.in'. Output is sent
to the standard output if TEMPLATE-FILE is given, else into
\`configure'.
Operation modes:
-h, --help print this help, then exit
-V, --version print version number, then exit
-v, --verbose verbosely report processing
-d, --debug don't remove temporary files
-f, --force consider all the files are obsolete
-o, --output=FILE save output in FILE (stdout is the default)
-W, --warnings=CATEGORY report the warnings falling in CATEGORY [syntax]
Warning categories include:
\`cross' cross compilation issues
\`obsolete' obsolete constructs
\`syntax' dubious syntactic constructs
\`all' all the warnings
\`no-CATEGORY' turn off the warnings on CATEGORY
\`none' turn off all the warnings
\`error' warnings are error
The environment variable \`WARNINGS' is honored.
Library directories:
-A, --autoconf-dir=ACDIR Autoconf's macro files location (rarely needed)
-l, --localdir=DIR location of the \`aclocal.m4' file
Tracing:
-t, --trace=MACRO report the list of calls to MACRO
-i, --initialization also trace Autoconf's initialization process
In tracing mode, no configuration script is created.
Report bugs to <bug-autoconf@gnu.org>."
