`autoconf'
==========

   The `autoconf' program produces a Bourne shell script called
`configure' from a template file called `configure.in'.  `configure.in'
contains both Bourne shell script, and `m4' macros.  `autoconf' expands
the `m4' macros into `real' shell script.  The resulting `configure'
script performs various checks for installed programs, compiler
characteristics and other system information such as available headers
and libraries. Note: GNU autoconf, for more information.

   GIMP-Print provides an `m4' macro, `AM_PATH_GIMPPRINT', suitable for
use in a `configure.in'. It defines the environment variables
`GIMPPRINT_CFLAGS', `GIMPPRINT_LIBS' and `GIMPPRINT_CONFIG'. You can
optionally specify a minimum version of the library to use, and shell
script to run if the test suceeds or fails.

 - Macro: AM_PATH_GIMPPRINT ([MINIMUM-VERSION [, ACTION-IF-FOUND [,
          ACTION-IF-NOT-FOUND]]])
     Check for an installed version of GIMP-Print greater than or equal
     to MINIMUM-VERSION.

     ACTION-IF-FOUND is a list of shell commands to run if the check
     for the library succeeds; ACTION-IF-NOT-FOUND is a list of shell
     commands to run if the check fails.

     The macro sets the following environment variables:
     `GIMPPRINT_CFLAGS', `GIMPPRINT_LIBS' and `GIMPPRINT_CONFIG'. It
     also will substitute them into any `Makefile.in' you specify in
     `AC_OUTPUT' because it calls `AC_SUBST' for each of them. However,
     you will probably be using `automake' to generate your
     `Makefile.in' files (Note: automake).
