<!--l. 115--><p class="indent"> You should install the packages either in the local tree or in your personal tree, depending on whether you have

files of the <span class="obeylines-h"><span class="verb"><span

class="E">E</span>X</span>’s filename database. This is done by running
the command <span class="obeylines-h"><span class="verb"><span
class="cmtt-10">texhash</span></span></span> or <span class="obeylines-h"><span class="verb"><span

class="cmtt-10">plain</span></span></span>, and <span class="obeylines-h"><span class="verb"><span
class="cmtt-10">latex</span></span></span>. You should “merge” each of the four directories with the following directories <span class="obeylines-h"><span class="verb"><span

<span class="obeylines-h"><span class="verb"><span

class="cmtt-10">texmf/tex/plain</span></span></span>, and <span class="obeylines-h"><span class="verb"><span
class="cmtt-10">texmf/tex/latex</span></span></span>. For example, in the <span class="obeylines-h"><span class="verb"><span
class="cmtt-10">.tar</span></span></span> file the <span class="obeylines-h"><span class="verb"><span
class="cmtt-10">doc</span></span></span> directory
contains just the directory <span class="obeylines-h"><span class="verb"><span
class="cmtt-10">pgf</span></span></span>, and this directory has to be moved to <span class="obeylines-h"><span class="verb"><span
class="cmtt-10">texmf/doc/pgf</span></span></span>. The root <span class="obeylines-h"><span class="verb"><span
class="cmtt-10">README</span></span></span> file can be
ignored since it is reproduced in <span class="obeylines-h"><span class="verb"><span

<h5 class="subsubsectionHead"><span class="titlemark">2.5.1 </span> <a
id="x3-190002.5.1"></a>Preamble</h5>
<!--l. 18--><p class="noindent">The licenses for most software are designed to take away your freedom to share and change it. By contrast, the <span
class="cmcsc-10"><small
class="small-caps">G</small><small
class="small-caps">N</small><small
class="small-caps">U</small></span>
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 <span
class="cmcsc-10"><small
class="small-caps">G</small><small
class="small-caps">N</small><small
class="small-caps">U</small> </span>Library General Public License instead.) You can apply it to your programs,
too.
<!--l. 27--><p class="indent"> 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.
<!--l. 34--><p class="indent"> 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.
<!--l. 39--><p class="indent"> 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.
<!--l. 44--><p class="indent"> 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.
<!--l. 48--><p class="indent"> 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.
<!--l. 55--><p class="indent"> 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.
<!--l. 61--><p class="indent"> The precise terms and conditions for copying, distribution and modification follow.
<!--l. 65--><p class="noindent">
<h5 class="subsubsectionHead"><span class="titlemark">2.5.2 </span> <a
id="x3-200002.5.2"></a>Terms and Conditions For Copying, Distribution and Modification</h5>
<!--l. 67--><p class="noindent">
<ol type="1" class="enumerate1" >
<li class="enumerate" value="0"
><a
id="x3-20002x0"></a>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”.
<!--l. 82--><p class="noindent">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.
</li>
<li class="enumerate" value="1"
><a
id="x3-20004x1"></a>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.
<!--l. 96--><p class="noindent">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.
</li>
<li class="enumerate" value="2"
><a
id="x3-20006x2"></a>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:
<!--l. 105--><p class="noindent">
<ol type="a" class="enumerate2" >
<li class="enumerate" value="1"
><a
id="x3-20008x1"></a>You must cause the modified files to carry prominent notices stating that you changed the files
and the date of any change.
</li>
<li class="enumerate" value="2"
><a
id="x3-20010x2"></a>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.
</li>
<li class="enumerate" value="3"
><a
id="x3-20012x3"></a>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.)
</li></ol>
<!--l. 132--><p class="noindent">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.
<!--l. 142--><p class="noindent">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.
<!--l. 147--><p class="noindent">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.
</li>
<li class="enumerate" value="3"
><a
id="x3-20014x3"></a>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:
<!--l. 157--><p class="noindent">
<ol type="a" class="enumerate2" >
<li class="enumerate" value="1"
><a
id="x3-20016x1"></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,
</li>
<li class="enumerate" value="2"
><a
id="x3-20018x2"></a>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,
</li>
<li class="enumerate" value="3"
><a
id="x3-20020x3"></a>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 Subsubsection
b above.)
</li></ol>
<!--l. 182--><p class="noindent">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.
<!--l. 193--><p class="noindent">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.
</li>
<li class="enumerate" value="4"
><a
id="x3-20022x4"></a>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.
</li>
<li class="enumerate" value="5"
><a
id="x3-20024x5"></a>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.
</li>
<li class="enumerate" value="6"
><a
id="x3-20026x6"></a>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.
</li>
<li class="enumerate" value="7"
><a
id="x3-20028x7"></a>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.
<!--l. 241--><p class="noindent">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.
<!--l. 246--><p class="noindent">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.
<!--l. 257--><p class="noindent">This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this
License.
</li>
<li class="enumerate" value="8"
><a
id="x3-20030x8"></a>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.
</li>
<li class="enumerate" value="9"
><a
id="x3-20032x9"></a>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.
<!--l. 275--><p class="noindent">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.
</li>
<li class="enumerate" value="10"
><a
id="x3-20034x10"></a>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.

<h5 class="subsubsectionHead"><span class="titlemark">2.5.3 </span> <a

<!--l. 296--><p class="noindent">
<ol type="1" class="enumerate1" >
<li class="enumerate" value="10"
><a
id="x3-21002x10"></a>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.
</li>
<li class="enumerate" value="11"
><a
id="x3-21004x11"></a>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.</li></ol>
