4## This file is a shell script fragment that supplies the information
5## necessary to tailor a template configure script into the configure
6## script appropriate for this directory. For more information, check
7## any existing configure script.
8
9## Be warned, there are two types of configure.in files. There are those
10## used by Autoconf, which are macros which are expanded into a configure
11## script by autoconf. The other sort, of which this is one, is executed
12## by Cygnus configure.
13
14## For more information on these two systems, check out the documentation
15## for 'Autoconf' (autoconf.texi) and 'Configure' (configure.texi).

36### or a host dependent tool. Then put it into the appropriate list
