+kdessh - a KDE front end to ssh
+
+Copyright (c) 1999,2000 by Geert Jansen <jansen@kde.org>
+
+                               The "Artistic License"
+
+                                      Preamble
+
+        The intent of this document is to state the conditions under which a
+        Package may be copied, such that the Copyright Holder maintains some
+        semblance of artistic control over the development of the package,
+        while giving the users of the package the right to use and
+        distribute the Package in a more-or-less customary fashion, plus the
+        right to make reasonable modifications.
+
+        Definitions:
+
+           * "Package" refers to the collection of files distributed by the
+             Copyright Holder, and derivatives of that collection of files
+             created through textual modification.
+
+           * "Standard Version" refers to such a Package if it has not been
+             modified, or has been modified in accordance with the wishes of
+             the Copyright Holder.
+
+           * "Copyright Holder" is whoever is named in the copyright or
+             copyrights for the package.
+
+           * "You" is you, if you're thinking about copying or distributing
+             this Package.
+
+           * "Reasonable copying fee" is whatever you can justify on the
+             basis of media cost, duplication charges, time of people
+             involved, and so on. (You will not be required to justify it to
+             the Copyright Holder, but only to the computing community at
+             large as a market that must bear the fee.)
+
+           * "Freely Available" means that no fee is charged for the item
+             itself, though there may be fees involved in handling the item.
+             It also means that recipients of the item may redistribute it
+             under the same conditions they received it.
+
+        1. You may make and give away verbatim copies of the source form of
+        the Standard Version of this Package without restriction, provided
+        that you duplicate all of the original copyright notices and
+        associated disclaimers.
+
+        2. You may apply bug fixes, portability fixes and other
+        modifications derived from the Public Domain or from the Copyright
+        Holder. A Package modified in such a way shall still be considered
+        the Standard Version.
+
+        3. You may otherwise modify your copy of this Package in any way,
+        provided that you insert a prominent notice in each changed file
+        stating how and when you changed that file, and provided that you do
+        at least ONE of the following:
+
+             a) place your modifications in the Public Domain or
+             otherwise make them Freely Available, such as by posting
+             said modifications to Usenet or an equivalent medium, or
+             placing the modifications on a major archive site such as
+             ftp.uu.net, or by allowing the Copyright Holder to include
+             your modifications in the Standard Version of the Package.
+
+             b) use the modified Package only within your corporation
+             or organization.
+
+             c) rename any non-standard executables so the names do not
+             conflict with standard executables, which must also be
+             provided, and provide a separate manual page for each
+             non-standard executable that clearly documents how it
+             differs from the Standard Version.
+
+             d) make other distribution arrangements with the Copyright
+             Holder.
+
+        4. You may distribute the programs of this Package in object code or
+        executable form, provided that you do at least ONE of the following:
+
+             a) distribute a Standard Version of the executables and
+             library files, together with instructions (in the manual
+             page or equivalent) on where to get the Standard Version.
+
+             b) accompany the distribution with the machine-readable
+             source of the Package with your modifications.
+
+             c) accompany any non-standard executables with their
+             corresponding Standard Version executables, giving the
+             non-standard executables non-standard names, and clearly
+             documenting the differences in manual pages (or
+             equivalent), together with instructions on where to get
+             the Standard Version.
+
+             d) make other distribution arrangements with the Copyright
+             Holder.
+
+        5. You may charge a reasonable copying fee for any distribution of
+        this Package. You may charge any fee you choose for support of this
+        Package. You may not charge a fee for this Package itself. However,
+        you may distribute this Package in aggregate with other (possibly
+        commercial) programs as part of a larger (possibly commercial)
+        software distribution provided that you do not advertise this
+        Package as a product of your own.
+
+        6. The scripts and library files supplied as input to or produced as
+        output from the programs of this Package do not automatically fall
+        under the copyright of this Package, but belong to whomever
+        generated them, and may be sold commercially, and may be aggregated
+        with this Package.
+
+        7. C or perl subroutines supplied by you and linked into this
+        Package shall not be considered part of this Package.
+
+        8. The name of the Copyright Holder may not be used to endorse or
+        promote products derived from this software without specific prior
+        written permission.
+
+        9. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR
+        IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
+        WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.
+
+                                      The End
