autoupdate
to Modernize configure.acThe autoupdate
program updates a configure.ac file that
calls Autoconf macros by their old names to use the current macro names.
In version 2 of Autoconf, most of the macros were renamed to use a more
uniform and descriptive naming scheme. See Macro Names, for a
description of the new scheme. Although the old names still work
(see Obsolete Macros, for a list of the old macros and the corresponding
new names), you can make your configure.ac files more readable
and make it easier to use the current Autoconf documentation if you
update them to use the new macro names.
If given no arguments, autoupdate
updates configure.ac,
backing up the original version with the suffix ~ (or the value
of the environment variable SIMPLE_BACKUP_SUFFIX
, if that is
set). If you give autoupdate
an argument, it reads that file
instead of configure.ac and writes the updated file to the
standard output.
autoupdate
accepts the following options:
Print a summary of the command line options and exit.
Print the version number of Autoconf and exit.
Report processing steps.
Don’t remove the temporary files.
Force the update even if the file has not changed. Disregard the cache.
Also look for input files in dir. Multiple invocations accumulate. Directories are browsed from last to first.
Prepend directory dir to the search path. This is used to include the language-specific files before any third-party macros.
