Notice:  Most of LinuxCNC is covered by the GNU General Public 
License.  Some portions are covered by the GNU Lesser 
General Public License (mostly interface definitions).
Both licenses are included in their entirety below.

Much of LinuxCNC is derived from the Enhanced Machine Controller, a
work of Fred Proctor, Tom Kramer, Will Shackleford, and others.
That work was originally released into the public domain.  It was
used as the basis of LinuxCNC, but received extensive modifications.
LinuxCNC is NOT public domain.  Anyone wishing to use the public
domain code in a way that is not compatible with the (L)GPL must
locate the original the Enhanced Machine Controller code - they may
NOT use LinuxCNC.

 Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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.

		    GNU GENERAL PUBLIC LICENSE
   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 sometimes
make exceptions for this.  Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.

			    NO WARRANTY

  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  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.

  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, 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.

		     END OF TERMS AND CONDITIONS

	    How to Apply These Terms to Your New Programs

  If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.

  To do so, attach the following notices to the program.  It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.

    <one line to give the program's name and a brief idea of what it does.>
    Copyright (C) <year>  <name of author>

    This program is free software; you can redistribute it and/or modify
    it under the terms of the GNU General Public License as published by
    the Free Software Foundation; either version 2 of the License, or
    (at your option) any later version.

    This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    GNU General Public License for more details.

    You should have received a copy of the GNU General Public License
    along with this program; if not, write to the Free Software
    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.


Also add information on how to contact you by electronic and paper mail.

If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:

    Gnomovision version 69, Copyright (C) year  name of author
    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    This is free software, and you are welcome to redistribute it
    under certain conditions; type `show c' for details.

The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License.  Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.

You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary.  Here is a sample; alter the names:

  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
  `Gnomovision' (which makes passes at compilers) written by James Hacker.

  <signature of Ty Coon>, 1 April 1989
  Ty Coon, President of Vice

This General Public License does not permit incorporating your program into
proprietary programs.  If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library.  If this is what you want to do, use the GNU Library General
Public License instead of this License.

GNU LESSER GENERAL PUBLIC LICENSE

Version 2.1, February 1999 

Copyright (C) 1991, 1999 Free Software Foundation, Inc.
51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.

[This is the first released version of the Lesser GPL.  It also counts
 as the successor of the GNU Library Public License, version 2, hence
 the version number 2.1.]

Preamble

The licenses for most software are designed to take away your freedom to
share and change it. By contrast, the GNU General Public Licenses are 
intended to guarantee your freedom to share and change free software--to 
make sure the software is free for all its users. 

This license, the Lesser General Public License, applies to some specially
designated software packages--typically libraries--of the Free Software 
Foundation and other authors who decide to use it. You can use it too, but
we suggest you first think carefully about whether this license or the 
ordinary General Public License is the better strategy to use in any 
particular case, based on the explanations below. 

When we speak of free software, we are referring to freedom of use, 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 and use pieces of it 
in new free programs; and that you are informed that you can do these
things. 

To protect your rights, we need to make restrictions that forbid 
distributors to deny you these rights or to ask you to surrender these 
rights. These restrictions translate to certain responsibilities for 
you if you distribute copies of the library or if you modify it. 

For example, if you distribute copies of the library, whether gratis or
for a fee, you must give the recipients all the rights that we gave you.
You must make sure that they, too, receive or can get the source code. 
If you link other code with the library, you must provide complete object
files to the recipients, so that they can relink them with the library 
after making changes to the library and recompiling it. And you must show
them these terms so they know their rights. 

We protect your rights with a two-step method: (1) we copyright the 
library, and (2) we offer you this license, which gives you legal 
permission to copy, distribute and/or modify the library. 

To protect each distributor, we want to make it very clear that there is
no warranty for the free library. Also, if the library is modified by 
someone else and passed on, the recipients should know that what they 
have is not the original version, so that the original author's reputation
will not be affected by problems that might be introduced by others. 

Finally, software patents pose a constant threat to the existence of any
free program. We wish to make sure that a company cannot effectively 
restrict the users of a free program by obtaining a restrictive license
from a patent holder. Therefore, we insist that any patent license 
obtained for a version of the library must be consistent with the full
freedom of use specified in this license. 

Most GNU software, including some libraries, is covered by the ordinary
GNU General Public License. This license, the GNU Lesser General Public
License, applies to certain designated libraries, and is quite different
from the ordinary General Public License. We use this license for certain
libraries in order to permit linking those libraries into non-free programs. 

When a program is linked with a library, whether statically or using a 
shared library, the combination of the two is legally speaking a combined
work, a derivative of the original library. The ordinary General Public 
License therefore permits such linking only if the entire combination fits
its criteria of freedom. The Lesser General Public License permits more lax
criteria for linking other code with the library. 

We call this license the "Lesser" General Public License because it does 
Less to protect the user's freedom than the ordinary General Public License.
It also provides other free software developers Less of an advantage over 
competing non-free programs. These disadvantages are the reason we use the 
ordinary General Public License for many libraries. However, the Lesser 
license provides advantages in certain special circumstances. 

For example, on rare occasions, there may be a special need to encourage 
the widest possible use of a certain library, so that it becomes a de-facto
standard. To achieve this, non-free programs must be allowed to use the 
library. A more frequent case is that a free library does the same job as
widely used non-free libraries. In this case, there is little to gain by 
limiting the free library to free software only, so we use the Lesser 
General Public License. 

In other cases, permission to use a particular library in non-free programs
enables a greater number of people to use a large body of free software. 
For example, permission to use the GNU C Library in non-free programs 
enables many more people to use the whole GNU operating system, as well 
as its variant, the GNU/Linux operating system. 

Although the Lesser General Public License is Less protective of the users'
freedom, it does ensure that the user of a program that is linked with the 
Library has the freedom and the wherewithal to run that program using a 
modified version of the Library. 

The precise terms and conditions for copying, distribution and modification
follow. Pay close attention to the difference between a "work based on the 
library" and a "work that uses the library". The former contains code derived
from the library, whereas the latter must be combined with the library in 
order to run. 

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

0. This License Agreement applies to any software library or other program
which contains a notice placed by the copyright holder or other authorized
party saying it may be distributed under the terms of this Lesser General 
Public License (also called "this License"). Each licensee is addressed as
"you". 

A "library" means a collection of software functions and/or data prepared
so as to be conveniently linked with application programs (which use some
of those functions and data) to form executables. 

The "Library", below, refers to any such software library or work which 
has been distributed under these terms. A "work based on the Library" 
means either the Library or any derivative work under copyright law: 
that is to say, a work containing the Library or a portion of it, either
verbatim or with modifications and/or translated straightforwardly into 
another language. (Hereinafter, translation is included without limitation
in the term "modification".) 

"Source code" for a work means the preferred form of the work for making
modifications to it. For a library, 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 library. 

Activities other than copying, distribution and modification are not covered
by this License; they are outside its scope. The act of running a program 
using the Library is not restricted, and output from such a program is 
covered only if its contents constitute a work based on the Library 
(independent of the use of the Library in a tool for writing it). Whether
that is true depends on what the Library does and what the program that 
uses the Library does. 

1. You may copy and distribute verbatim copies of the Library's complete
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 distribute a copy of this 
License along with the Library. 

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 Library or any portion of it, 
thus forming a work based on the Library, 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) The modified work must itself be a software library. 
b) You must cause the files modified to carry prominent notices stating
that you changed the files and the date of any change. 
c) You must cause the whole of the work to be licensed at no charge 
to all third parties under the terms of this License. 
d) If a facility in the modified Library refers to a function or a 
table of data to be supplied by an application program that uses the
facility, other than as an argument passed when the facility is invoked,
then you must make a good faith effort to ensure that, in the event an 
application does not supply such function or table, the facility still 
operates, and performs whatever part of its purpose remains meaningful. 

(For example, a function in a library to compute square roots has a 
purpose that is entirely well-defined independent of the application.
Therefore, Subsection 2d requires that any application-supplied function
or table used by this function must be optional: if the application does
not supply it, the square root function must still compute square roots.) 

These requirements apply to the modified work as a whole. If identifiable
sections of that work are not derived from the Library, 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 Library, 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 Library. 

In addition, mere aggregation of another work not based on the Library with
the Library (or with a work based on the Library) on a volume of a storage 
or distribution medium does not bring the other work under the scope of 
this License. 

3. You may opt to apply the terms of the ordinary GNU General Public License
instead of this License to a given copy of the Library. To do this, you must
alter all the notices that refer to this License, so that they refer to the 
ordinary GNU General Public License, version 2, instead of to this License. 
(If a newer version than version 2 of the ordinary GNU General Public License
has appeared, then you can specify that version instead if you wish.) Do not
make any other change in these notices. 

Once this change is made in a given copy, it is irreversible for that copy, 
so the ordinary GNU General Public License applies to all subsequent copies 
and derivative works made from that copy. 

This option is useful when you wish to copy part of the code of the Library
into a program that is not a library. 

4. You may copy and distribute the Library (or a portion or derivative of 
it, under Section 2) in object code or executable form under the terms of 
Sections 1 and 2 above provided that you 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. 

If distribution of 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 satisfies the requirement to distribute the source 
code, even though third parties are not compelled to copy the source 
along with the object code. 

5. A program that contains no derivative of any portion of the Library, 
but is designed to work with the Library by being compiled or linked with
it, is called a "work that uses the Library". Such a work, in isolation, 
is not a derivative work of the Library, and therefore falls outside the 
scope of this License. 

However, linking a "work that uses the Library" with the Library creates
an executable that is a derivative of the Library (because it contains 
portions of the Library), rather than a "work that uses the library". 
The executable is therefore covered by this License. Section 6 states 
terms for distribution of such executables. 

When a "work that uses the Library" uses material from a header file 
that is part of the Library, the object code for the work may be a 
derivative work of the Library even though the source code is not. 
Whether this is true is especially significant if the work can be 
linked without the Library, or if the work is itself a library. 
The threshold for this to be true is not precisely defined by law. 

If such an object file uses only numerical parameters, data structure
layouts and accessors, and small macros and small inline functions 
(ten lines or less in length), then the use of the object file is 
unrestricted, regardless of whether it is legally a derivative work.
(Executables containing this object code plus portions of the Library
will still fall under Section 6.) 

Otherwise, if the work is a derivative of the Library, you may 
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6, whether
or not they are linked directly with the Library itself. 

6. As an exception to the Sections above, you may also combine or link
a "work that uses the Library" with the Library to produce a work 
containing portions of the Library, and distribute that work under 
terms of your choice, provided that the terms permit modification of
the work for the customer's own use and reverse engineering for 
debugging such modifications. 

You must give prominent notice with each copy of the work that the 
Library is used in it and that the Library and its use are covered 
by this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the 
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do 
one of these things: 

a) Accompany the work with the complete corresponding machine-readable
source code for the Library including whatever changes were used in the
work (which must be distributed under Sections 1 and 2 above); and, if 
the work is an executable linked with the Library, with the complete 
machine-readable "work that uses the Library", as object code and/or 
source code, so that the user can modify the Library and then relink 
to produce a modified executable containing the modified Library. (It 
is understood that the user who changes the contents of definitions 
files in the Library will not necessarily be able to recompile the 
application to use the modified definitions.) 
b) Use a suitable shared library mechanism for linking with the Library.
A suitable mechanism is one that (1) uses at run time a copy of the 
library already present on the user's computer system, rather than 
copying library functions into the executable, and (2) will operate 
properly with a modified version of the library, if the user installs
one, as long as the modified version is interface-compatible with the
version that the work was made with. 
c) Accompany the work with a written offer, valid for at least three 
years, to give the same user the materials specified in Subsection 6a,
above, for a charge no more than the cost of performing this distribution. 
d) If distribution of the work is made by offering access to copy from a
designated place, offer equivalent access to copy the above specified 
materials from the same place. 
e) Verify that the user has already received a copy of these materials or
that you have already sent this user a copy. 

For an executable, the required form of the "work that uses the Library"
must include any data and utility programs needed for reproducing the 
executable from it. However, as a special exception, the materials to be
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. 

It may happen that this requirement contradicts the license restrictions of
other proprietary libraries that do not normally accompany the operating 
system. Such a contradiction means you cannot use both them and the Library
together in an executable that you distribute. 

7. You may place library facilities that are a work based on the Library 
side-by-side in a single library together with other library facilities 
not covered by this License, and distribute such a combined library, provided
that the separate distribution of the work based on the Library and of the 
other library facilities is otherwise permitted, and provided that you do 
these two things: 

a) Accompany the combined library with a copy of the same work based on the
Library, uncombined with any other library facilities. This must be 
distributed under the terms of the Sections above. 
b) Give prominent notice with the combined library of the fact that part
of it is a work based on the Library, and explaining where to find the 
accompanying uncombined form of the same work. 

8. You may not copy, modify, sublicense, link with, or distribute the Library
except as expressly provided under this License. Any attempt otherwise to 
copy, modify, sublicense, link with, or distribute the Library 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. 

9. 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 Library or its derivative works. These actions are prohibited by law 
if you do not accept this License. Therefore, by modifying or distributing
the Library (or any work based on the Library), you indicate your acceptance
of this License to do so, and all its terms and conditions for copying, 
distributing or modifying the Library or works based on it. 

10. Each time you redistribute the Library (or any work based on the Library),
the recipient automatically receives a license from the original licensor to 
copy, distribute, link with or modify the Library 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 with this License. 

11. 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 Library at all. For example, if a patent license would not permit 
royalty-free redistribution of the Library 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 Library. 

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. 

12. If the distribution and/or use of the Library is restricted in certain
countries either by patents or by copyrighted interfaces, the original 
copyright holder who places the Library 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. 

13. The Free Software Foundation may publish revised and/or new versions
of the Lesser 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 Library 
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 Library does not specify a license version 
number, you may choose any version ever published by the Free Software 
Foundation. 

14. If you wish to incorporate parts of the Library into other free programs
whose distribution conditions are incompatible with these, 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 sometimes make exceptions
for this. Our decision will be guided by the two goals of preserving the free 
status of all derivatives of our free software and of promoting the sharing 
and reuse of software generally. 

NO WARRANTY 

15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR 
THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE 
LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, 
INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND 
PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE,
YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 

16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE 
THE LIBRARY 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 LIBRARY (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 LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF 
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
