Autoconf 2.13 -*- text -*- ------------- This is the Debian packaging of Autoconf 2.13, an obsolete release of the Autoconf system for creating configuration scripts using templates. This version of Autoconf is obsolete and its use is deprecated. It is troublesome to determine which programs need this compatibility package and adapt them for it. As a result, this package has wrappers for autoconf, autoheader, and autoreconf. Each of these attempts to detect which Autoconf is needed and run the correct version of the tool. There are no wrappers for autoupdate, autoscan, or ifnames. These are not used during a package build. Choose the proper version by hand. The following heuristics are used to choose an Autoconf version: * If file `configure.ac' exists, Autoconf 2.50 is used. Autoconf 2.13 used the name `configure.in' instead, but version 2.50 supports both. (Usually autoconf is run without nonoption arguments. If a filename is supplied on the command line, then version 2.50 is used if the filename ends in `.ac'.) * Otherwise, `configure.in' (or the file specified on the command line, if any) is read. It is checked for the presence of an AC_PREREQ directive. If it specifies a minimum version higher than 2.13, Autoconf 2.50 is used. `aclocal.m4', if present, is also scanned. * Otherwise, Autoconf 2.13 is used. To force Autoconf 2.13 to be used, name the Autoconf input file `configure.in' and omit the use of AC_PREREQ() or specify a minimum version of 2.13 or earlier. To force Autoconf 2.50 to be used, name the input file `configure.ac' or use AC_PREREQ(2.50). I recommend not calling the programs autoconf2.13 or autoconf2.50, etc., directly, instead of through the wrappers. When used with programs like Automake, these direct calls won't propagate through into the Makefile, so later re-autoconf'ings won't use the correct version. It's better to use one of the methods explained above to force a particular version.
