| 3 | ## This file is a shell script fragment that supplies the information |
| 4 | ## necessary to tailor a template configure script into the configure |
| 5 | ## script appropriate for this directory. For more information, check |
| 6 | ## any existing configure script. |
| 7 | |
| 8 | ## Be warned, there are two types of configure.in files. There are those |
| 9 | ## used by Autoconf, which are macros which are expanded into a configure |
| 10 | ## script by autoconf. The other sort, of which this is one, is executed |
| 11 | ## by Cygnus configure. |
| 12 | |
| 13 | ## For more information on these two systems, check out the documentation |
| 14 | ## for 'Autoconf' (autoconf.texi) and 'Configure' (configure.texi). |
