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.

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.

13: ## For more information on these two systems, check out the documentation
14: ## for 'Autoconf' (autoconf.texi) and 'Configure' (configure.texi).
