+
+ Be kind to Automake: list the arguments of selected macros
+ (for instance AC_SUBST will list each variable which may be
+ substitued).
+
+ * autoconf.sh (--trace, --output): New options.
+ Implement tracing of macros.
+ trap also on 0, so that there is no need to rm here and there.
+ * autoconf.texi (Output): Document --trace and --output.

Clean up the macros for testing members of aggregates.
ridiculously small, so that people see a framework in which they may
provide their additional tests.
+** AC_INCLUDE
+I think shell globbing is a bad thing. In particular, this is bad for
+automake. I think we should make it static, i.e., very much like
+AC_CONFIG_ things. So there would no problems of localization, some
+macros may AC_INCLUDE files etc.
+
** testsuite/config/unix.exp
Fix the regex snippet so that it properly parses the current version
of Autoconf.
** Allow --recursive to config.status
So that --recheck does not pass --no-recursive to configure.
-** Allow --header, --command, --file to config.status.
-./config.status --file foo, would work on foo as if it were a config
-file. It would be great that we could use stdin and stdout also.
-
** Move AM_PROG_CC_STDC into Autoconf.
Autoconf should provide the means to determine the ANSIsm of the
compiler, not Automake.

+@item --trace=@var{macro}
+@itemx -t @var{macro}
+List the calls to @var{macro}. Multiple calls to @samp{--trace} list
+several macros. It is adviced to use this feature instead of parsing
+@file{configure.in}.
+
+The output is composed of separated lines for each macro call. Each
+line follows this model:
+@example
+% ./autoconf -t AC_INIT -t AM_INIT_AUTOMAKE
+configure.in:2:AC_INIT:acgeneral.m4
+configure.in:3:AM_INIT_AUTOMAKE:autoconf, 2.14a
+@end example
+
+@item --output=@var{file}
+@itemx -o @var{file}
+Save output (script or traces) to @var{file}. The file @samp{-} stands
+for the standard output.

told which files to load, and in which order.

+@maindex INCLUDE
Read the macro definitions that appear in the listed files. A list of
space-separated filenames or shell globbing patterns is expected. The
files will be read in the order they're listed.
Generate a configuration script from a TEMPLATE-FILE if given, or
`configure.in' by default. Output is sent to the standard output if
TEMPLATE-FILE is given, else into `configure'.
