The *MySQL* server license for non Microsoft operating systems
**************************************************************
*MySQL FREE PUBLIC LICENSE*
(Version 4, March 5, 1995)
Copyright (C) 1995, 1996 TcX AB & Monty Program KB & Detron HB
Stockholm SWEDEN, Helsingfors FINLAND and Uppsala SWEDEN
All rights reserved.
NOTE: This license is not the same as any of the GNU Licenses published
by the Free Software Foundation. Its terms are substantially different
from those of the GNU Licenses. If you are familiar with the GNU
Licenses, please read this license with extra care.
This License applies to the computer program known as "MySQL". The
"Program", below, refers to such program, and a "work based on the
Program" means either the Program or any derivative work of the Program,
as defined in the United States Copyright Act of 1976, such as a
translation or a modification. The Program is a copyrighted work whose
copyright is held by TcX Datakonsult AB and Monty Program KB and Detron
HB.
This License does not apply when running "MySQL" on any Microsoft
operating system. Microsoft operating systems include all versions of
Microsoft Windows NT and Microsoft Windows.
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. NOTHING OTHER THAN THIS LICENSE GRANTS
YOU PERMISSION TO MODIFY OR DISTRIBUTE THE PROGRAM OR ITS DERIVATIVE
WORKS. THESE ACTIONS ARE PROHIBITED BY LAW. IF YOU DO NOT ACCEPT THESE
TERMS AND CONDITIONS, DO NOT MODIFY OR DISTRIBUTE THE PROGRAM.
1. Licenses.
Licensor hereby grants you the following rights, provided that you
comply with all of the restrictions set forth in this License and
provided, further, that you distribute an unmodified copy of this
License with the Program:
a. You may copy and distribute literal (i.e., verbatim) copies
of the Program's source code as you receive it throughout the
world, in any medium.
b. You may modify the Program, create works based on the Program
and distribute copies of such throughout the world, in any
medium.
2. Restrictions.
This license is subject to the following restrictions:
a. Distribution of the Program or any work based on the Program
by a commercial organization to any third party is prohibited
if any payment is made in connection with such distribution,
whether directly (as in payment for a copy of the Program) or
indirectly (as in payment for some service related to the
Program, or payment for some product or service that includes
a copy of the Program "without charge"; these are only
examples, and not an exhaustive enumeration of prohibited
activities). However, the following methods of distribution
involving payment shall not in and of themselves be a
violation of this restriction:
A. Posting the Program on a public access information
storage and retrieval service for which a fee is
received for retrieving information (such as an on-line
service), provided that the fee is not content-dependent
(i.e., the fee would be the same for retrieving the same
volume of information consisting of random data).
B. Distributing the Program on a CD-ROM, provided that the
files containing the Program are reproduced entirely and
verbatim on such CD-ROM, and provided further that all
information on such CD-ROM be redistributable for
non-commercial purposes without charge.
b. Activities other than copying, distribution and modification
of the Program are not subject to this License and they are
outside its scope. Functional use (running) of the Program
is not restricted, and any output produced through the use of
the Program is subject to this license only if its contents
constitute a work based on the Program (independent of having
been made by running the Program).
c. You must meet all of the following conditions with respect to
the distribution of any work based on the Program:
A. If you have modified the Program, you must cause your
work to carry prominent notices stating that you have
modified the Program's 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
and 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, at each time
the modified program commences operation, 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). Such
notice must also state that users may redistribute the
Program only under the conditions of this License and
tell the user how to view the copy of this License
included with the Program. (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.);
D. You must accompany any such work based on the Program
with the complete corresponding machine-readable source
code, delivered on a medium customarily used for
software interchange. 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 code. However, 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 code;
E. If you distribute any written or printed material at all
with the Program or any work based on the Program, such
material must include either a written copy of this
License, or a prominent written indication that the
Program or the work based on the Program is covered by
this License and written instructions for printing
and/or displaying the copy of the License on the
distribution medium;
F. You may not impose any further restrictions on the
recipient's exercise of the rights granted herein.
If distribution of executable or object code is made by
offering the equivalent ability to copy from a
designated place, then offering equivalent ability 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 code along
with the object code.
3. Reservation of Rights.
No rights are granted to the Program except as expressly set forth
herein. 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.
4. Other Restrictions.
If the distribution and/or use of the Program is restricted in
certain countries for any reason, Licensor 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.
5. Limitations.
THE PROGRAM IS PROVIDED TO YOU "AS IS," WITHOUT WARRANTY. THERE IS
NO WARRANTY FOR THE PROGRAM, EITHER EXPRESSED OR IMPLIED,
INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE AND
NONINFRINGEMENT OF THIRD PARTY RIGHTS. THE ENTIRE RISK AS TO THE
QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
SERVICING, REPAIR OR CORRECTION.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL LICENSOR, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE
THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA
BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF
THE POSSIBILITY OF SUCH DAMAGES.

Virtual IO library.
IO wrappers for sockets, fd-s, SSL.
Languages:C++
This library is based on work of many others.
They have different policies and I haven't thought up
about resulting licence - GPL, L(essen)GPL, BSD-style, whatever.
The licences are here for reference:
COPYING.mysql: MySQL licence. Some socket functions.
COPYING.dbug: Fred Fish's dbug library. I use it extensively ;=)
COPYING.openssl:OpenSSL licence. SSL wrappers.
At the moment there is no real 'Makefile', just config.mk/targets.mk
and Makefile.am to build it as a module in MySQL. Therefore, there
is currently no possibility to build it as a separate library, but
with MySQL-s root Makefile it should just a matter of leaving
everything else out.
