  2. Autoconf
  3. Autoconf is an extensible package of M4 macros that produce shell
  4. scripts to automatically configure software source code packages.
  5. These scripts can adapt the packages to many kinds of UNIX-like
  6. systems without manual user intervention. Autoconf creates a
  7. configuration script for a package from a template file that lists the
  8. operating system features that the package can use, in the form of M4
  9. macro calls.
  10. Producing configuration scripts using Autoconf requires GNU M4 and
  11. Perl. You should install GNU M4 (version 1.4.6 or later is required;
  12. 1.4.14 or later is recommended) and Perl (5.006 or later) before
  13. configuring Autoconf, so that Autoconf's configure script can find
  14. them. The configuration scripts produced by Autoconf are
  15. self-contained, so their users do not need to have Autoconf (or GNU
  16. M4, Perl, etc.).
  17. You can get GNU M4 here:
  18. ftp://ftp.gnu.org/gnu/m4/
  19. The file INSTALL should be distributed with packages that use
  20. Autoconf-generated configure scripts and Makefiles that conform to the
  21. GNU coding standards. The package's README can just give an overview
  22. of the package, where to report bugs, and a pointer to INSTALL for
  23. instructions on compilation and installation. This removes the need
  24. to maintain many similar sets of installation instructions.
  25. Be sure to read BUGS and INSTALL.
  26. Mail suggestions to autoconf@gnu.org, report bugs to
  27. bug-autoconf@gnu.org, and submit patches to autoconf-patches@gnu.org.
  28. All changes can be tracked at the read-only autoconf-commit@gnu.org.
  29. Always include the Autoconf version number, which you can get by
  30. running `autoconf --version'. Archives of bug-autoconf@gnu.org can be
  31. found in <http://lists.gnu.org/archive/html/bug-autoconf/>, and
  32. similarly for the other mailing lists.
