dnl Process this file with autoconf to produce a configure script.
dnl
dnl This file configure.in is part of the t1lib-package (V. 1.0).

dnl Author:         Rainer Menzner (Rainer.Menzner@web.de)

dnl We set CFLAGS in order to have complete control over compiler 
dnl switches during development
dnl CFLAGS="$CFLAGS -g -Wall"


dnl The following variables specify version information of the 
dnl library. Starting with V. 1.0.0 the libtool scheme is used 
dnl as intended by its authors.
dnl
dnl Note: The name of the shared library on Linux is build as
dnl       libt1.so.$(T1LIB_LT_CURRENT)-$(T1LIB_LT_AGE).$(T1LIB_LT_AGE).$(T1LIB_LT_REVISION)

dnl Since I'm forgetful sometimes, I quote the libtool infopage here:
dnl
dnl  1. Start with version information of `0:0:0' for each libtool library.
dnl
dnl  2. Update the version information only immediately before a public
dnl     release of your software.  More frequent updates are unnecessary,
dnl     and only guarantee that the current interface number gets larger
dnl     faster.
dnl
dnl  3. If the library source code has changed at all since the last
dnl     update, then increment REVISION (`C:R:A' becomes `C:r+1:A').
dnl
dnl  4. If any interfaces have been added, removed, or changed since the
dnl     last update, increment CURRENT, and set REVISION to 0.
dnl
dnl  5. If any interfaces have been added since the last public release,
dnl     then increment AGE.
dnl
dnl  6. If any interfaces have been removed since the last public release,
dnl     then set AGE to 0.
