This is the GNU/Linux prepackaged version of pdksh, a public domain clone
of the AT&T Korn shell..
This Debian package is currently maintained by Robert Luberda <robert@debian.org>
It was put together from sources obtained from:
ftp://ftp.cs.mun.ca/pub/pdksh/pdksh-5.2.14.tar.gz
Former maintainers were Mark Baker, Larry Daffner, Martin Schulze
and Ian Murdock.
PDksh itself is currently being maintained by Michael Rendell
(michael@cs.mun.ca), who took over from Simon J. Gerraty
(sjg@zen.void.oz.au) at the later's suggestion.
pdksh is provided AS IS, with NO WARRANTY, either expressed or implied.
The vast majority of the code that makes pdksh is in the public domain.
The exceptions are:
sigact.c and sigact.h

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.
On Debian systems the full text of the GPL license can
be found in the /usr/share/common-licenses file.
