+ This is covered by the GNU General Public Licence (GPL)
+ as it contains modified versions of macros that come with
+ GNU autoconf. As this is used solely for configuration,
+ the pdksh code itself is not covered by the GPL.
+ The following is taken from autoconf 2.x documentation
+ (info autoconf questions distributing) concerning use
+ of autoconf in programs:
+
+ There are no restrictions on how the configuration
+ scripts that Autoconf produces may be distributed
+ or used. In Autoconf version 1, they were covered by
+ the GNU General Public License. We still encourage
+ software authors to distribute their work under terms
+ like those of the GPL, but doing so is not required
+ to use Autoconf.
+
+That's it. Short and simple.
