+\section*{How the GNU General Public License Applies to Junicode}
+
+The GPL is intended to protect conventional software programs. Though
+fonts are software programs, they are something of a special case, for
+several reasons.
+
+First, the GPL requires that “source code” be distributed or made
+available whenever a program is distributed. “Source code” is “the
+preferred form of the work for making modifications to it.” For a
+TrueType font, that “preferred form” is just as likely to be the
+executable file, the binary font file, as anything else, since every
+major font editor allows the developer to open such a file, edit it,
+and save it again. Indeed, the binary TrueType format is more portable
+than the “source code” used by such programs as FontForge and
+FontLab. For this reason, {\bfseries if you create a font based on
+Junicode, you are not required to distribute source code for it other
+than the binary, “executable” font.} In a TrueType font, it is
+possible to set a flag to signal that the font may not be edited. In
+keeping with the spirit of the GPL, {\bfseries you must not set this
+flag}.
+
+Second, the manner in which a font is distributed may differ from that
+of a conventional program. Specifically, portions of a font, rather
+than the whole thing, may be embedded in a PDF file, web page, or
+other kind of document. It is unclear whether the various tools that
+produce such documents embed the font’s copyright notice along with
+the font itself. Nevertheless, {\bfseries nothing in the GPL should be
+ construed as prohibiting the embedding of a font in a document}. The
+font should always be marked “embeddable.” The developer of Junicode
+does not hold that the relationship between a font and the document in
+which it is embedded is the same as that between a subroutine library
+and a program in which it is incorporated. Your using Junicode does
+not restrict the licensing or copyright status of your document. On
+this point the developer of Junicode speaks only for himself and not
+for other font developers.
+
+Third, if you intend to edit Junicode you need to be aware that some
+font editors may insert program code that is incompatible with the GPL
+into a font. This is not true of FontForge, the program used to
+develop Junicode; it is certainly not true of Xgridfit, the GPL
+language compiler used to “hint” the font. But FontLab appears to
+insert a library of its own code into fonts that it “autohints” or
+that are hinted by its graphical hinter. The developer of Junicode has
+been unable to ascertain the legal status of this code, which
+{\itshape may} be incompatible with the GPL. {\bfseries If you intend
+to use FontLab or another proprietary tool (such as Microsoft’s VTT)
+for hinting, you should first make sure that doing so will not violate
+the GPL.} Contact the vendor of the tool you want to use if you are in
+doubt. Do not direct such questions to the developer of Junicode.

+
+Version 2, June 1991
+
+Copyright © 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.
+
+\subsection*{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.
+
+\subsection*{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.
+
+\subsection*{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
+
+\subsection*{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., 59 Temple Place, Suite 330, Boston, MA 02111-1307
+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.

+
+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.
