+GNU GENERAL PUBLIC LICENSE
+
+   Version 2, June 1991
+Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+59 Temple Place - Suite 330, Boston, MA  02111-1307, USA
+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+
+Preamble
+
+   The licenses for most software are designed to take away your freedom
+   to share and change it. By contrast, the GNU General Public License is
+   intended to guarantee your freedom to share and change free
+   software--to make sure the software is free for all its users. This
+   General Public License applies to most of the Free Software
+   Foundation's software and to any other program whose authors commit to
+   using it. (Some other Free Software Foundation software is covered by
+   the GNU Library General Public License instead.) You can apply it to
+   your programs, too.
+   
+   When we speak of free software, we are referring to freedom, not
+   price. Our General Public Licenses are designed to make sure that you
+   have the freedom to distribute copies of free software (and charge for
+   this service if you wish), that you receive source code or can get it
+   if you want it, that you can change the software or use pieces of it
+   in new free programs; and that you know you can do these things.
+   
+   To protect your rights, we need to make restrictions that forbid
+   anyone to deny you these rights or to ask you to surrender the rights.
+   These restrictions translate to certain responsibilities for you if
+   you distribute copies of the software, or if you modify it.
+   
+   For example, if you distribute copies of such a program, whether
+   gratis or for a fee, you must give the recipients all the rights that
+   you have. You must make sure that they, too, receive or can get the
+   source code. And you must show them these terms so they know their
+   rights.
+   
+   We protect your rights with two steps: (1) copyright the software, and
+   (2) offer you this license which gives you legal permission to copy,
+   distribute and/or modify the software.
+   
+   Also, for each author's protection and ours, we want to make certain
+   that everyone understands that there is no warranty for this free
+   software. If the software is modified by someone else and passed on,
+   we want its recipients to know that what they have is not the
+   original, so that any problems introduced by others will not reflect
+   on the original authors' reputations.
+   
+   Finally, any free program is threatened constantly by software
+   patents. We wish to avoid the danger that redistributors of a free
+   program will individually obtain patent licenses, in effect making the
+   program proprietary. To prevent this, we have made it clear that any
+   patent must be licensed for everyone's free use or not licensed at
+   all.
+   
+   The precise terms and conditions for copying, distribution and
+   modification follow.
+   
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+   0. This License applies to any program or other work which contains a
+   notice placed by the copyright holder saying it may be distributed
+   under the terms of this General Public License. The "Program", below,
+   refers to any such program or work, and a "work based on the Program"
+   means either the Program or any derivative work under copyright law:
+   that is to say, a work containing the Program or a portion of it,
+   either verbatim or with modifications and/or translated into another
+   language. (Hereinafter, translation is included without limitation in
+   the term "modification".) Each licensee is addressed as "you".
+   
+   Activities other than copying, distribution and modification are not
+   covered by this License; they are outside its scope. The act of
+   running the Program is not restricted, and the output from the Program
+   is covered only if its contents constitute a work based on the Program
+   (independent of having been made by running the Program). Whether that
+   is true depends on what the Program does.
+   
+   1. You may copy and distribute verbatim copies of the Program's source
+   code as you receive it, in any medium, provided that you conspicuously
+   and appropriately publish on each copy an appropriate copyright notice
+   and disclaimer of warranty; keep intact all the notices that refer to
+   this License and to the absence of any warranty; and give any other
+   recipients of the Program a copy of this License along with the
+   Program.
+   
+   You may charge a fee for the physical act of transferring a copy, and
+   you may at your option offer warranty protection in exchange for a
+   fee.
+   
+   2. You may modify your copy or copies of the Program or any portion of
+   it, thus forming a work based on the Program, and copy and distribute
+   such modifications or work under the terms of Section 1 above,
+   provided that you also meet all of these conditions:
+   
+     * a) You must cause the modified files to carry prominent notices
+       stating that you changed the files and the date of any change.
+     * b) You must cause any work that you distribute or publish, that in
+       whole or in part contains or is derived from the Program or any
+       part thereof, to be licensed as a whole at no charge to all third
+       parties under the terms of this License.
+     * c) If the modified program normally reads commands interactively
+       when run, you must cause it, when started running for such
+       interactive use in the most ordinary way, to print or display an
+       announcement including an appropriate copyright notice and a
+       notice that there is no warranty (or else, saying that you provide
+       a warranty) and that users may redistribute the program under
+       these conditions, and telling the user how to view a copy of this
+       License. (Exception: if the Program itself is interactive but does
+       not normally print such an announcement, your work based on the
+       Program is not required to print an announcement.)
+       
+   These requirements apply to the modified work as a whole. If
+   identifiable sections of that work are not derived from the Program,
+   and can be reasonably considered independent and separate works in
+   themselves, then this License, and its terms, do not apply to those
+   sections when you distribute them as separate works. But when you
+   distribute the same sections as part of a whole which is a work based
+   on the Program, the distribution of the whole must be on the terms of
+   this License, whose permissions for other licensees extend to the
+   entire whole, and thus to each and every part regardless of who wrote
+   it.
+   
+   Thus, it is not the intent of this section to claim rights or contest
+   your rights to work written entirely by you; rather, the intent is to
+   exercise the right to control the distribution of derivative or
+   collective works based on the Program.
+   
+   In addition, mere aggregation of another work not based on the Program
+   with the Program (or with a work based on the Program) on a volume of
+   a storage or distribution medium does not bring the other work under
+   the scope of this License.
+   
+   3. You may copy and distribute the Program (or a work based on it,
+   under Section 2) in object code or executable form under the terms of
+   Sections 1 and 2 above provided that you also do one of the following:
+     * a) Accompany it with the complete corresponding machine-readable
+       source code, which must be distributed under the terms of Sections
+       1 and 2 above on a medium customarily used for software
+       interchange; or,
+     * b) Accompany it with a written offer, valid for at least three
+       years, to give any third party, for a charge no more than your
+       cost of physically performing source distribution, a complete
+       machine-readable copy of the corresponding source code, to be
+       distributed under the terms of Sections 1 and 2 above on a medium
+       customarily used for software interchange; or,
+     * c) Accompany it with the information you received as to the offer
+       to distribute corresponding source code. (This alternative is
+       allowed only for noncommercial distribution and only if you
+       received the program in object code or executable form with such
+       an offer, in accord with Subsection b above.)
+       
+   The source code for a work means the preferred form of the work for
+   making modifications to it. For an executable work, complete source
+   code means all the source code for all modules it contains, plus any
+   associated interface definition files, plus the scripts used to
+   control compilation and installation of the executable. However, as a
+   special exception, the source code distributed need not include
+   anything that is normally distributed (in either source or binary
+   form) with the major components (compiler, kernel, and so on) of the
+   operating system on which the executable runs, unless that component
+   itself accompanies the executable.
+   
+   If distribution of executable or object code is made by offering
+   access to copy from a designated place, then offering equivalent
+   access to copy the source code from the same place counts as
+   distribution of the source code, even though third parties are not
+   compelled to copy the source along with the object code.
+   
+   4. You may not copy, modify, sublicense, or distribute the Program
+   except as expressly provided under this License. Any attempt otherwise
+   to copy, modify, sublicense or distribute the Program is void, and
+   will automatically terminate your rights under this License. However,
+   parties who have received copies, or rights, from you under this
+   License will not have their licenses terminated so long as such
+   parties remain in full compliance.
+   
+   5. You are not required to accept this License, since you have not
+   signed it. However, nothing else grants you permission to modify or
+   distribute the Program or its derivative works. These actions are
+   prohibited by law if you do not accept this License. Therefore, by
+   modifying or distributing the Program (or any work based on the
+   Program), you indicate your acceptance of this License to do so, and
+   all its terms and conditions for copying, distributing or modifying
+   the Program or works based on it.
+   
+   6. Each time you redistribute the Program (or any work based on the
+   Program), the recipient automatically receives a license from the
+   original licensor to copy, distribute or modify the Program subject to
+   these terms and conditions. You may not impose any further
+   restrictions on the recipients' exercise of the rights granted herein.
+   You are not responsible for enforcing compliance by third parties to
+   this License.
+   
+   7. If, as a consequence of a court judgment or allegation of patent
+   infringement or for any other reason (not limited to patent issues),
+   conditions are imposed on you (whether by court order, agreement or
+   otherwise) that contradict the conditions of this License, they do not
+   excuse you from the conditions of this License. If you cannot
+   distribute so as to satisfy simultaneously your obligations under this
+   License and any other pertinent obligations, then as a consequence you
+   may not distribute the Program at all. For example, if a patent
+   license would not permit royalty-free redistribution of the Program by
+   all those who receive copies directly or indirectly through you, then
+   the only way you could satisfy both it and this License would be to
+   refrain entirely from distribution of the Program.
+   
+   If any portion of this section is held invalid or unenforceable under
+   any particular circumstance, the balance of the section is intended to
+   apply and the section as a whole is intended to apply in other
+   circumstances.
+   
+   It is not the purpose of this section to induce you to infringe any
+   patents or other property right claims or to contest validity of any
+   such claims; this section has the sole purpose of protecting the
+   integrity of the free software distribution system, which is
+   implemented by public license practices. Many people have made
+   generous contributions to the wide range of software distributed
+   through that system in reliance on consistent application of that
+   system; it is up to the author/donor to decide if he or she is willing
+   to distribute software through any other system and a licensee cannot
+   impose that choice.
+   
+   This section is intended to make thoroughly clear what is believed to
+   be a consequence of the rest of this License.
+   
+   8. If the distribution and/or use of the Program is restricted in
+   certain countries either by patents or by copyrighted interfaces, the
+   original copyright holder who places the Program under this License
+   may add an explicit geographical distribution limitation excluding
+   those countries, so that distribution is permitted only in or among
+   countries not thus excluded. In such case, this License incorporates
+   the limitation as if written in the body of this License.
+   
+   9. The Free Software Foundation may publish revised and/or new
+   versions of the General Public License from time to time. Such new
+   versions will be similar in spirit to the present version, but may
+   differ in detail to address new problems or concerns.
+   
+   Each version is given a distinguishing version number. If the Program
+   specifies a version number of this License which applies to it and
+   "any later version", you have the option of following the terms and
+   conditions either of that version or of any later version published by
+   the Free Software Foundation. If the Program does not specify a
+   version number of this License, you may choose any version ever
+   published by the Free Software Foundation.
+   
+   10. If you wish to incorporate parts of the Program into other free
+   programs whose distribution conditions are different, write to the
+   author to ask for permission. For software which is copyrighted by the
+   Free Software Foundation, write to the Free Software Foundation; we

+onak 0.0.1
+
+First release. You're mostly on your own folks.
+
+Developed under Linux & FreeBSD. Not currently autoconfed, so might need some
+tweaking to compile under anything else (or indeed either of those with header
+files in different places).
+
+The DB2 support for pksd databases is read only at present. It was knocked up
+in an hour to get the pathfinder working with the wwwkeys.uk.pgp.net DB.
+
+File database backend support is good for testing.
+
+It's running on hell.on.earth.li; currently with just under 400 keys in the
+database (Postgres backend). This isn't merging with anything at present
+though; that's the next step which is sort of there.
+
+You want to put add & lookup in a /pks directory under a web server running on
+port 11371 to make gpg happy. There's a mathopd.conf file that I used for
+testing, however I'm now running it under Apache for the public test rig as
+that host already runs it.
+
+Really needs a config file so all the hardcoded stuff isn't any more.
+
+Patches to do stuff welcome. Bug reports welcome. Don't expect quick responses
+though. ;)
