PHP buildconf

A wrapper around the autoconf and autoheader that generate files for building
PHP on *nix systems (configure and main/php_config.h.in). The configure script
is used to customize the PHP build based on the provided options and system. PHP
releases downloaded from PHP.net already include the configure script so
installing Autoconf and running buildconf is not needed. For the PHP sources
from the Git repository, buildconf is used for generating a new configure script
and required files.

SYNOPSIS:
  buildconf [<options>]

OPTIONS:
  -f, --force     Regenerate configure files in PHP release packages.
  --debug         Display warnings emitted by Autoconf.
  -h, --help      Display this help.

ENVIRONMENT:
  The following optional variables are supported:

  PHP_AUTOCONF    Overrides the path to autoconf tool.
                  PHP_AUTOCONF=/path/to/autoconf ./buildconf
  PHP_AUTOHEADER  Overrides the path to autoheader tool.
                  PHP_AUTOHEADER=/path/to/autoheader ./buildconf
