+Changes to vpl2vpl between first (unnumbered) release and release 0.1
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When I first wrote vpl2vpl I was under the impression that the vpl
+file output by afm2tfm could never contain accented character
+definitions. The first (unnumbered) release of vpl2vpl thus did not
+implement the -b option allowed for mkt1font (to block the use of
+predefined accented characters). I have since become aware that in
+the rather rare case of an afm file containing composite character
+information, afm2tfm uses that information to build definitions of
+accented characters; I have therefore introduced a -b option in
+version 0.1.
+
+There were two bugs in the coding dealing with the -s option in the
+first version of vpl2vpl. First, the shrink-factor specified by the
+user was incorrectly applied to the underdot accent as well as to
+dropped superscript accents. Second, the shrink-factor was not
+correctly scaled in terms of the value of DESIGNUNITS (this chiefly
+affected Computer Modern fonts). Both of these have been fixed in
+version 0.1.
+
+Another bug affected those characters (quotesingle, quotedbl,
+backslash, underscore, braceleft, bar and braceright) which
+dvips.enc places in the lower half of the character set, but which
+vpl2vpl removes to make room for the normal TeX inhabitants of their
+"slots"; in the first version of the program it was not possible to
+include these characters in the output font. This has also been
+fixed in version 0.1.
+
+The handling of LIGTABLE information controlling kerning etc. has
+been improved, to eliminate repeated instructions and "orphaned"
+instructions with no LABEL.
+
+In the first version of vpl2vpl I deliberately did not allow for
+double superscript accents on tall characters such as capital
+letters, on the grounds that this would be bad typographic practice.
+A specific request for one such character has led me to modify
+version 0.1 of the program to make the creation of such characters
+possible, but I would still argue against their use.
+
+Some minor improvements have been made to the code in various areas,
+including checking for inappropriate input, calculation of italic
+correction for characters with superscript accents, and placing of
+dropped superscript accents. (However, it is likely that such
+accents will still sometimes require manual intervention.)
+
+
+Changes to mkt1font between first (unnumbered) release and release 0.1
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In the first release of mkt1font, kerning information for predefined
+accented characters was taken from the input font, even if the -b
+option had been specified to force the redefinition of such
+characters. This has been fixed in version 0.1: if the -b option is
+used, kerns for characters such as "eacute" are generalised from the
+kerns for "e" in just the same way as happens for "emacron" etc.
+
+Similarly, predefined accented characters eliminated by the -b
+option used to retain "ghost" entries among the unencoded characters
+in the afm file. This too has been fixed in version 0.1.
+
+As of version 0.1, any composite character definitions contained in
+the afm file of the input font are eliminated from the output font,
+since they will almost certainly be incomplete, and (if the user has
+specified -b) will probably be wrong as well.
+
+Version 0.1 can now properly process input fonts using MS-DOS file
+format (with newline represented by CR/LF). It can also process
+fonts in which the character "|" is used in the names of the
+frequently used "noaccess def" and "noaccess put" definitions
+(previously this fell foul of Perl's regular expression handler).
+
+As with vpl2vpl, I have modified version 0.1 of mkt1font to permit
+the creation of tall characters bearing double superscript accents,
+though I do not recommend the use of such characters.
+
+The "FontBBox" entries in the afm and pfb files now reflect any
+increase in the maximum height or depth of characters in the output
+font.
+
+Various other minor improvements have been made to the code,
+including the placing of dropped superscript accents. (As with
+vpl2vpl, however, it is likely that such accents will still
+sometimes require manual intervention.)
+
+
+Changes between release 0.1 and release 0.2
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A. Changes common to both programs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+I have implemented the candrabindu ("moon-dot") accent sometimes
+used in Indian-language material. This is achieved by overprinting a
+breve with a dotaccent; a new command-line option (-c) has been
+introduced to allow for font-specific adjustments in the placing of
+the dotaccent.
+
+The user's command-line is now stored as a comment at the head of
+the output file(s).
+
+The constraint on the ordering of definitions in a definition file
+has been removed: it is no longer necessary to ensure that a
+character is defined before it is used.
+
+Digraphs are now implemented: if the character specified as the
+"accent" in a definition is not in fact a valid accent character,
+the definition is interpreted as a request for a digraph formed from
+the "character" followed by the "accent".
+
+A bug which placed superscript accents incorrectly over tall
+characters already bearing "under" accents has been fixed.
+
+The vertical positioning of "under" accents has been adjusted: they
+are now placed slightly lower than previously.
+
+
+B. Changes to vpl2vpl
+~~~~~~~~~~~~~~~~~~~~~
+
+Fixed a bug which resulted in some accents in small caps fonts being
+positioned at the wrong height.
+
+Fixed a bug which resulted in small amounts of LIGTABLE information
+being lost.
+
+
+C. Changes to mkt1font
+~~~~~~~~~~~~~~~~~~~~~~
+
+The internal organisation of the program has been cleaned up in a
+number of respects. In particular, various subroutines are now
+called with the appropriate formal parameters, rather than relying
+on the existence of equivalent global variables; the fetching and
+storing of character metric information is tidier and more
+efficient; and kerning information is dealt with in the course of
+the main program loop, rather than in a private (double) loop
+afterwards.
+
+The -s option allowing "under" accents to be shrunk by a specified
+factor, which was previously available only in vpl2vpl, has now been
+implemented in mkt1font also.
+
+The output afm file previously sometimes contained spurious entries
+for unencoded characters that duplicated items in the list of
+encoded characters. This has been fixed.
+
+Despite the fix introduced in version 0.1, some predefined kerning
+information continued to find its way into the afm file even when
+the -b option was specified to block the use of predefined accented
+characters. A new, improved fix is now in place to prevent this. An
+error in a regular expression which generated some undesirable kerns
+has also been corrected.
+
+The "FontBBox" entries in the afm and pfb files now reflect any
+increase in the maximum width of characters in the output font, as
+well as increases in their maximum height or depth.
+
+Fixed a bug causing the underbar accent to be too long.
+
+Fixed a bug causing "under" accents to be assigned the wrong depth:
+this could result in the bottom of the accent failing to print
+properly.
+
+
+Changes between release 0.2 and release 0.21
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Changes common to both programs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The vertical positioning of "under" accents has been adjusted again
+(the previous adjustment was a little too enthusiastic). They have
+been raised slightly.
+
+The height at which characters are reckoned to be so tall that
+superscript accents placed on them must be raised above the normal
+level has been increased slightly (from 1.1 x xheight to 1.15 x
+xheight).
+
+Changes between release 0.21 and release 0.211
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A. Changes to vpl2vpl
+~~~~~~~~~~~~~~~~~~~~~
+
+A single minor change has been made to vpl2vpl: this has been
+necessitated by a change in the format of the LIGTABLE information
+produced by version 8.1 of afm2tfm, which now adds identificatory
+comments to lines referring to characters by means of octal
+notation. Vpl2vpl strips out such comments.
+
+
+B. Changes to mkt1font
+~~~~~~~~~~~~~~~~~~~~~~
+
+Minor bugfixes have been put in place: extra spaces in the the
+"noaccess def" and "noaccess put" definitions are now permitted, and
+so is a character named ".null". An error message has been improved.
+
+Changes between release 0.211 and release 0.212
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A. Changes to vpl2vpl
+~~~~~~~~~~~~~~~~~~~~~
+
+Fixed a bug in the "double superscript accent on small caps
+character" routine.
+
+
+B. Changes to mkt1font
+~~~~~~~~~~~~~~~~~~~~~~
+
+Fixed a bug which produced incorrect output in cases where the
+character to be accented is defined as blank (e.g. space).
+
+Changes to between release 0.212 and release 0.22
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Changes common to both programs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The programs now recognise "commaaccent" as a valid subscript
+accent. Note that they cannot replace this subscript with the
+superscript form used with the letter "g" (any more than they can
+substitute the apostrophe-like form of the caron that is used with
+"L", "d", "l" and "t"). Note also that as there is no position for
+this accent in either the standard TeX encoding or the dvips.enc
+variant, vpl2vpl will not actually be able to use it to build new
+characters without further modification.
+
+In the case where the definition file specifies, say, "z overdot"
+and the font contains a predefined version named "zdotaccent", it
+previously happened that the output font contained both characters.
+This has been fixed: now only the character requested in the
+definition file exists in the output.
+
+Changes between release 0.22 and release 0.221
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A. Changes to mkt1font
+~~~~~~~~~~~~~~~~~~~~~~
+
+Fixed a bug which caused the program to fail after incorrectly
+identifying CharStrings definitions.
+
+Changes tbetween release 0.221 and release 0.222
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A. Changes to mkt1font
+~~~~~~~~~~~~~~~~~~~~~~
+
+Changed FamilyName to remove only the final one of a number of
+hyphenated elements from the font name.
+
+Changes tbetween release 0.222 and release 0.23
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A. Changes to mkt1font
+~~~~~~~~~~~~~~~~~~~~~~
+
+No changes have in fact been made to mkt1font, but its version number
+has been raised to 0.23 to confirm with those of vpl2vpl and vpl2ovp.
+
+B. Changes to vpl2vpl
+~~~~~~~~~~~~~~~~~~~~~
+
+A change has been introduced to permit the program to use the output
+of the AFM conversion utility afm2pl, rather than the earlier afm2tfm.
+This has been done because it has come to light that afm2tfm gives
+incorrect values for the heights of some characters, which can cause
+poor accent placement. Support for the output of afm2tfm has not been
+withdrawn, but afm2pl is now definitely preferred.
+
+B. A new program: vpl2ovp
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The greatest change as of 0.23 is the addition of a third program to
+the suite. Vpl2ovp does essentially the same job as vpl2vpl, in that
+it creates virtual fonts that contain arbitrarily accented characters,
+but its output is a .ovp file suitable for use with Omega (the 16-bit
+Unicode-aware development from TeX). Using vpl2ovp it is possible to
+build substantial Unicode-compliant virtual fonts for use with Omega,
+and a .def file for the set of characters I have included in my
+earlier "IndUni" OpenType fonts is now included in the distribution.
+(IndUni virtual fonts for Omega created with vpl2ovp are available at
+http://bombay.indology.info/software/fonts/induni/index.html.) Glyphs
+representing characters requiring more than a single codepoint are
+stored in the Private Use Area, and a system of ligatures is provided
+to allow them to be accessed. This system also permits
+single-codepoint accented characters to be accessed through their
+"decomposed" component parts. Thus if the characters a-macron (single
+codepoint: U+0101) and a-macron-acute (two codepoints: U+0101 +
+U+0301) are defined, the former will be accessible both as U+0101
+(a-macron) and as U+0061 + U+0304 ("a" + macron); the latter will be
+accessible both as U+0101 + U+0301 (a-macron + acute) and U+0061 +
+U+0304 + U+0301 ("a" + macron + acute). This is a considerable
+advantage, given the different possible ways in which Unicode can be,
+and is, used.

+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 675 Mass Ave, Cambridge, MA 02139, 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

+
+ 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.

+
+ Mkt1font, vpl2vpl and vpl2ovp: programs to generate accented fonts
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ John D. Smith
+ ~~~~~~~~~~~~~
+
+
+These three programs, all made available under the GNU General Public
+License, address the same requirement using the same basic algorithms:
+their aim is to make it easy to create versions of existing fonts
+containing whatever accented characters the user may need, arranged
+according to whatever encoding he/she may favour. Mkt1font does this
+by reading in the two files that define a Type 1 PostScript font and
+writing out new versions of them; vpl2vpl does it by reading in the
+file that defines a TeX virtual font and writing out a new version of
+it; vpl2ovp does the same as vpl2vpl, but its output is a 16-bit
+virtual font suitable for Omega, the Unicode-aware development from
+TeX. In each case information about what accented characters are
+required and where they should be located is supplied by means of a
+simple definition file, which has the same format for both programs.
+
+Note that most Type 1 PostScript fonts are commercial products
+subject to both copyright and licensing restrictions. If the license
+for such a font forbids reverse-engineering it, it is presumably
+illegal to run mkt1font on it; in any case it would certainly be a
+serious breach of copyright to make modified versions of the font
+available to third parties. The author of mkt1font will not be held
+responsible for any such misuses of the software. (No such legal
+problems surround the use of TeX virtual fonts, which merely specify
+new ways to use existing fonts.) However, would-be users may wish to
+note the existence of a body of high-quality freeware lookalikes for
+many of the standard Type 1 fonts: like mkt1font and vpl2vpl, the
+Ghostscript fonts developed by URW++ Design and Development
+Incorporated are made available under the GNU General Public License
+(see the file COPYING), which permits them to be modified and
+redistributed provided that certain simple decencies are observed.
+These fonts are available from many ftp sites, including those
+forming the Comprehensive TeX Archive Network (CTAN), for example
+ftp.tex.ac.uk: look for the most recent font archive file in the
+directory /tex-archive/support/ghostscript/gnu/fonts.
+
+A detailed specification of the form of the definition file used by
+mkt1font and vpl2vpl is given below in the instructions for using the
+programs, but it may be helpful to give a quick idea of its contents
+here. Each line of the file contains something similar to "128 x
+acute", which is an instruction to create a new character formed from
+"x" with an acute accent and located at position 128 in the character
+set. Once a new character has been defined in this way, it "exists" in
+just the same way as any other character, under the name "xacute" (or
+whatever); thus it can even receive further accents. The two lines
+
+ 129 e macron
+ 130 emacron breve
+
+will create a "long e" and a "long-or-short e" at the positions
+specified. (If only the latter is desired, they can both be assigned
+the same position in the encoding -- the second will overwrite the
+first.) Subscript as well as superscript accents are available. Some
+sample definition files are included to give an idea of the format:
+note that two of these (CSX.def and Norman.def), used for Indian
+language material in Roman script, contain the triple-accented
+character "runderdotmacron acute"!
+
+In addition to accented characters proper, both programs can produce
+digraphs -- single characters composed of pairs of other characters.
+In itself this may seem to be of limited use, since the digraph
+should always be indistinguishable from its two constituent
+characters printed consecutively. However, some Unicode-style
+encodings require that certain character-pairs be treated as
+digraphs. In addition, use of a digraph in subsequent definitions
+allows an accent to be applied to two characters as a pair: so, for
+example,
+
+ 131 k h
+ 131 kh underbar
+
+will produce a character consisting of an underlined "kh" at
+position 131.
+
+The algorithms used in both programs take great care to secure the
+most attractive results, placing accents centrally over/under their
+characters at appropriate heights/depths, varying their position
+according to the angle of slant in Italic and similar fonts,
+providing new characters with kerning information (which will be
+resolutely ignored by most word-processors), and -- in the case of
+mkt1font -- giving hinting instructions to improve output on
+low-resolution printers. However, users may feel that some
+characters need "tweaking". This tends to happen when the part of
+the character adjacent to the accent is highly asymmetrical:
+subscript accents below "r" may need moving to the left, while
+superscript accents above "d" may need moving to the right. It is
+relatively easy to modify the output of vpl2vpl to make such
+improvements by hand (vpl files are designed to be easy for humans
+to read, and vpl2vpl identifies each character with a comment). Type
+1 fonts are another matter; mkt1font generates a human-readable and
+commented ".dis" file as well as the ".pfb" font file, and it is
+possible to make changes to this and rebuild the pfb file with t1asm
+(see below), but this is not quite as simple as modifying a TeX
+virtual font.
+
+For details on how vpl2ovp handles access to accented characters by
+means of a system of ligatures, see further the CHANGES file.
+
+The programs are written in Perl, and have not been tested on
+systems other than Unix. (Apart from the #! line at the top, the
+only Unix specificities the author is aware of are two references to
+"/dev/null" in mkt1font and the general assumption that filenames
+can be of any length.) At run time, mkt1font invokes two further
+font utilities, t1asm and t1disasm, written by I. Lee Hetherington
+and available from CTAN ftp sites: look in the directory
+/tex-archive/fonts/utilities/t1utils.
+
+Detailed instructions for using the programs follow. In each case
+these instructions can also be seen by typing the name of the program
+with a "-h" option.
+
+
+Mkt1font
+~~~~~~~~
+Syntax: mkt1font -n fontname -d definition-file -a afm-file -f font-file
+ [-s shrink-factor] [-c candrabindu-adjustment] [-b]
+
+Mkt1font creates new Type 1 PostScript fonts based on existing fonts
+("input fonts"). In order to do this it makes use of I. Lee
+Hetherington's programs t1asm and t1disasm, which must be present on
+the system. A successful run will generate an AFM file and a PFB
+file, as well as a DIS file containing a disassembled version of the
+PFB file (including useful comments). Four options must be specified
+on the command line, as follows:
+
+ -n should name the font it is intended to generate. Avoid names
+ such as "myfont", as both mkt1font and other programs attempt
+ to draw conclusions from the name; better would be something
+ like "Utopia_French-BoldItalic". The generated font files will
+ also use this for their basename.
+
+ -d should refer to a font definition file. This file (which could
+ usefully be named, e.g., "French.def") should consist of lines
+ of character definitions, in the form
+ "number" "character"
+ or
+ "number" "character" "accent"
+ Here "number" represents the character's position in the new
+ encoding and may be expressed in decimal, octal or hex;
+ "character" names the character (e.g. "comma", "eight", "A")
+ or consists of the word ".notdef" (indicating that the
+ specified number's "slot" in the new encoding is to be empty);
+ and "accent" optionally names an accent to be placed on the
+ character. In addition to the standard accents available in
+ PostScript fonts, "underbar" and "underdot" are also available,
+ as are "under" versions of all the normal superscript accents
+ ("underdieresis", "underring", etc.). The Indian accent
+ "candrabindu" may also be specified: it is formed by
+ overprinting a breve with a dotaccent. Finally, "overdot" may
+ be used as a synonym for "dotaccent".
+
+ If the character named in the "accent" position is not in fact
+ a valid accent character, the program interprets the definition
+ as a request for a digraph formed from the "character" and the
+ "accent". A digraph consisting of, say, "k" and "h" will be
+ indistinguishable from the letters "k" and "h" printed
+ consecutively, but the digraph "kh" can itself receive accents
+ like any other character: see next paragraph.
+
+ A new character (such as "amacron" or "kh") may be freely
+ used in the "character" position of a further definition (such
+ as "amacron breve" or "kh underbar"). There is no constraint
+ on the ordering of definitions within a definition file. The
+ definition of "a macron" does not have to precede that of
+ "amacron breve": requests for "impossible" characters are
+ deferred until their constituents have had a chance to come into
+ being.
+
+ "Slots" for which no new definition is given retain the
+ definition they have in the input font.
+
+ The definition file may also contain blank lines and comments
+ (introduced by "#").
+
+ -a should refer to the AFM (Adobe Font Metrics) file for the input
+ font.
+
+ -f should refer to the binary font file (PFB) for the input font.
+ (In fact the equivalent ASCII file (PFA) is also acceptable for
+ input, but the output font is always in PFB format.)
+
+ -s may optionally give the factor, expressed as a per-thousand
+ value, by which normally superscript accents (such as dieresis,
+ ring) should be shrunk when they are used as subscript accents
+ (such as underdieresis, underring). Values of around 800 may be
+ found useful.
+
+ -c may optionally give two comma-separated numerical values to
+ adjust the x and y coordinates of the dotaccent placed within a
+ breve to form the candrabindu accent.
+
+ -b may optionally be specified to block the use of predefined
+ accented characters, forcing mkt1font to define its own
+ versions. This may be useful to secure a consistent appearance
+ in cases where a font designer does not share mkt1font's views
+ on where accents should be placed.
+
+The -h option prints this help.
+
+
+Vpl2vpl
+~~~~~~~
+Syntax: vpl2vpl -d definition-file [-s shrink-factor]
+ [-c candrabindu-adjustment] [-b] vpl-file
+
+Vpl2vpl creates new TeX virtual fonts based on existing virtual
+fonts ("input fonts"). A successful run will read a vpl (Virtual
+Property List) file and a definition file, and will generate a new
+vpl file on standard output. The input font is assumed to adhere to
+the standard TeX encoding for text fonts unless it was created with
+the program afm2tfm, in which case it is assumed to conform to the
+encoding specified in the file dvips.enc. In either case, the name
+of the input font is assumed to be the name of the input file
+without its .vpl extension: it must conform to normal TeX
+conventions for naming fonts, as vpl2vpl attempts to draw
+conclusions from it about the kind of font it is dealing with.
+
+In the case of a non-virtual font (such as the Computer Modern
+fonts), use a pl (Property List) file, created with the standard
+utility tftopl, as the input file in place of a vpl file; vpl2vpl
+will make the necessary changes on the fly.
+
+A typical complete sequence of commands to create a new virtual
+font might therefore be
+ tftopl cmr10.tfm cmr10.pl
+ vpl2vpl -d ISO-Latin1.def cmr10.pl >cmr10_isol1.vpl
+ vptovf cmr10_isol1.vpl cmr10_isol1.vf cmr10_isol1.tfm
+for a Computer Modern font, or
+ afm2pl Times-Roman.afm rptmr.pl
+ pltotf rptmr.pl rptmr.tfm
+ vpl2vpl -d ISO-Latin1.def rptmr.pl >ptmr-isol1.vpl
+ vptovf ptmr-isol1.vpl ptmr-isol1.vf ptmr-isol1.tfm
+for a PostScript font.
+
+Another approach for a PostScript font is to use afm2tfm:
+ afm2tfm Times-Roman.afm -t dvips.enc -v ptmr rptmr
+ vpl2vpl -d ISO-Latin1.def ptmr.vpl >ptmr-isol1.vpl
+ vptovf ptmr-isol1.vpl ptmr-isol1.vf ptmr-isol1.tfm
+-- but this is now deprecated, as afm2tfm generates incorrect
+values for the heights of some characters, and this can lead to
+bad accent placing.
+
+In order to keep the whole upper half of the character set free for
+the requirements of the encoding specified in the definition file,
+certain modifications are made to input fonts following the
+dvips.enc encoding to bring them into greater conformity with the
+TeX norm. In particular, the characters dotaccent and hungarumlaut
+are placed in the positions assigned by TeX ("5F, "7D), not those
+enforced by dvips.enc ("C7, "CD). The f-ligatures, double quotes and
+dashes are also moved from the upper half of the character set to
+their normal TeX positions. As a result, the following characters
+are not found in the lower half of the character set: quotesingle,
+quotedbl, backslash, underscore, braceleft, bar, braceright. These
+characters can, however, be assigned positions in the output font if
+they are needed. (Indeed, they could all be explicitly restored to
+their dvips.enc positions if this were desired.)
+
+Options:
+
+ -d should refer to a font definition file. This file (which could
+ usefully be named, e.g., "French.def") should consist of lines
+ of character definitions, in the form
+ "number" "character"
+ or
+ "number" "character" "accent"
+
+ Here "number" represents the character's position in the new
+ encoding and may be expressed in decimal, octal or hex;
+ "character" names the character (e.g. "comma", "eight", "A") or
+ consists of the word ".notdef" (indicating that the specified
+ number's "slot" in the new encoding is to be empty); and
+ "accent" optionally names an accent to be placed on the
+ character. In addition to the standard accents available in
+ PostScript fonts, "underbar" and "underdot" are also available,
+ as are "under" versions of all the normal superscript accents
+ ("underdieresis", "underring", etc.). The Indian accent
+ "candrabindu" may also be specified: it is formed by

+ "DESIGNUNITS R 1000" is assumed.
+
+ -b may optionally be specified to block the use of predefined
+ accented characters, forcing vpl2vpl to define its own

+
+
+Vpl2ovp
+~~~~~~~
+
+Syntax: vpl2ovp -d definition-file [-s shrink-factor]
+ [-c candrabindu-adjustment] [-b] vpl-file
+
+Vpl2ovp creates new Omega virtual fonts based on existing TeX
+virtual fonts ("input fonts"). A successful run will read a vpl
+(Virtual Property List) file and a definition file, and will generate
+a new ovp file on standard output. The input font is assumed to adhere
+to the standard TeX encoding for text fonts unless it was created with
+the program afm2tfm, in which case it is assumed to conform to the
+encoding specified in the file dvips.enc. In either case, the name

+ \"character\" names the character (e.g. \"comma\", \"eight\",
+ \"A\") or consists of the word \".notdef\" (indicating that
+ the specified number's \"slot\" in the new encoding is to be
+ empty); and \"accent\" optionally names an accent to be placed
+ on the character. In addition to the standard accents available
+ in PostScript fonts, \"underbar\" and \"underdot\" are also
+ available, as are \"under\" versions of all the normal
+ superscript accents (\"underdieresis\", \"underring\", etc.).
+ The Indian accent \"candrabindu\" may also be specified: it
+ is formed by overprinting a breve with a dotaccent. Finally,
+ \"overdot\" may be used as a synonym for \"dotaccent\".
+
+ If the character named in the \"accent\" position is not in fact
+ a valid accent character, the program interprets the definition
+ as a request for a digraph formed from the \"character\" and the
+ \"accent\". A digraph consisting of, say, \"k\" and \"h\" will be
+ indistinguishable from the letters \"k\" and \"h\" printed
+ consecutively, but the digraph \"kh\" can itself receive accents
+ like any other character: see next paragraph.
+
+ A new character (such as \"amacron\" or \"kh\") may be freely
+ used in the \"character\" position of a further definition (such
+ as \"amacron breve\" or \"kh underbar\"). There is no constraint
+ on the ordering of definitions within a definition file. The
+ definition of \"a macron\" does not have to precede that of
+ \"amacron breve\": requests for \"impossible\" characters are
+ deferred until their constituents have had a chance to come into
+ being.
+
+ \"Slots\" for which no new definition is given retain the
+ definition they have in the input font.
+
+ The definition file may also contain blank lines and comments
+ (introduced by \"\#\").
+
+ -a should refer to the AFM (Adobe Font Metrics) file for the input
+ font.
+
+ -f should refer to the binary font file (PFB) for the input font.
+ (In fact the equivalent ASCII file (PFA) is also acceptable for
+ input, but the output font is always in PFB format.)
+
+ -s may optionally give the factor, expressed as a per-thousand
+ value, by which normally superscript accents (such as dieresis,
+ ring) should be shrunk when they are used as subscript accents
+ (such as underdieresis, underring). Values of around 800 may be
+ found useful.
+
+ -c may optionally give two comma-separated numerical values to
+ adjust the x and y coordinates of the dotaccent placed within a
+ breve to form the candrabindu accent.
+
+ -b may optionally be specified to block the use of predefined
+ accented characters, forcing mkt1font to define its own
+ versions. This may be useful to secure a consistent appearance
+ in cases where a font designer does not share mkt1font's views
+ on where accents should be placed.
+
+The -h option prints this help.

+"Syntax: vpl2ovp -d definition-file [-s shrink-factor]
+ [-c candrabindu-adjustment] [-b] vpl-file
+
+Vpl2ovp creates new Omega virtual fonts based on existing TeX
+virtual fonts (\"input fonts\"). A successful run will read a vpl
+(Virtual Property List) file and a definition file, and will generate
+a new ovp file on standard output. The input font is assumed to adhere
+to the standard TeX encoding for text fonts unless it was created with
+the program afm2tfm, in which case it is assumed to conform to the
+encoding specified in the file dvips.enc. In either case, the name
+of the input font is assumed to be the name of the input file
+without its .vpl extension: it must conform to normal TeX
+conventions for naming fonts, as vpl2ovp attempts to draw
+conclusions from it about the kind of font it is dealing with.
+
+In the case of a non-virtual font (such as the Computer Modern
+fonts), use a pl (Property List) file, created with the standard
+utility tftopl, as the input file in place of a vpl file; vpl2ovp
+will make the necessary changes on the fly.
+
+A typical complete sequence of commands to create a new virtual
+font might therefore be
+ tftopl cmr10.tfm cmr10.pl
+ vpl2ovp -d Unicode1.def cmr10.pl >cmr10-uni1.ovp
+ ovp2ovf cmr10-uni1.ovp cmr10-uni1.ovf cmr10-uni1.ofm
+for a Computer Modern font, or
+ afm2pl Times-Roman.afm rptmr.pl
+ pltotf rptmr.pl rptmr.tfm
+ vpl2ovp -d Unicode1.def rptmr.pl >ptmr-uni1.ovp
+ ovp2ovf ptmr-uni1.ovp ptmr-uni1.ovf ptmr-uni1.ofm
+for a PostScript font.
+
+Another approach for a PostScript font is to use afm2tfm:
+ afm2tfm Times-Roman.afm -t dvips.enc -v ptmr rptmr
+ vpl2ovp -d Unicode1.def ptmr.vpl >ptmr-uni1.ovp
+ ovp2ovf ptmr-uni1.ovp ptmr-uni1.ovf ptmr-uni1.ofm
+-- but this is now deprecated, as afm2tfm generates incorrect
+values for the heights of some characters, and this can lead to
+bad accent placing.
+
+In order to keep the whole of the character range \"F0-\"FF free
+for the requirements of the encoding specified in the definition
+file, certain modifications are made to input fonts following the
+dvips.enc encoding to bring them into greater conformity with the
+TeX norm. In particular, the characters dotaccent and hungarumlaut
+are placed in the positions assigned by TeX (\"5F, \"7D), not those
+enforced by dvips.enc (\"C7, \"CD). The f-ligatures, double quotes
+and dashes are also moved from the upper half of the character set
+to their normal TeX positions. As a result, the following characters
+are not found in the lower half of the character set: quotesingle,
+quotedbl, backslash, underscore, braceleft, bar, braceright. These
+characters can, however, be assigned positions in the output font if
+they are needed. (Indeed, they could all be explicitly restored to
+their dvips.enc positions if this were desired.)
+
+Options:
+
+ -d should refer to a font definition file. This file (which could
+ usefully be named, e.g., \"French.def\") should consist of
+ lines of character definitions, in the form
+ \"number\" \"character\"
+ or
+ \"number\" \"character\" \"accent\"
+ Here \"number\" represents the character's position in the new
+ encoding and may be expressed in decimal, octal or hex;
+ \"character\" names the character (e.g. \"comma\", \"eight\",
+ \"A\") or consists of the word \".notdef\" (indicating that
+ the specified number's \"slot\" in the new encoding is to be
+ empty); and \"accent\" optionally names an accent to be placed
+ on the character. In addition to the standard accents available
+ in PostScript fonts, \"underbar\" and \"underdot\" are also
+ available, as are \"under\" versions of all the normal
+ superscript accents (\"underdieresis\", \"underring\", etc.).
+ The Indian accent \"candrabindu\" may also be specified: it
+ is formed by overprinting a breve with a dotaccent. Finally,
+ \"overdot\" may be used as a synonym for \"dotaccent\".
+
+ If the character named in the \"accent\" position is not in fact
+ a valid accent character, the program interprets the definition
+ as a request for a digraph formed from the \"character\" and the
+ \"accent\". A digraph consisting of, say, \"k\" and \"h\" will be
+ indistinguishable from the letters \"k\" and \"h\" printed
+ consecutively, but the digraph \"kh\" can itself receive accents
+ like any other character: see next paragraph.
+
+ A new character (such as \"amacron\" or \"kh\") may be freely
+ used in the \"character\" position of a further definition (such
+ as \"amacron breve\" or \"kh underbar\"). There is no constraint
+ on the ordering of definitions within a definition file. The
+ definition of \"a macron\" does not have to precede that of
+ \"amacron breve\": requests for \"impossible\" characters are
+ deferred until their constituents have had a chance to come into
+ being.
+
+ \"Slots\" for which no new definition is given retain the
+ definition they have in the input font.
+
+ The definition file may also contain blank lines and comments
+ (introduced by \"\#\").
+
+ -s may optionally give the factor, expressed as a per-thousand
+ value, by which normally superscript accents (such as dieresis,
+ ring) should be shrunk when they are used as subscript accents
+ (such as underdieresis, underring). Values of around 800 may be
+ found useful.
+
+ -c may optionally give two comma-separated numerical values to
+ adjust the x and y coordinates of the dotaccent placed within a
+ breve to form the candrabindu accent. A coordinate scheme using
+ \"DESIGNUNITS R 1000\" is assumed.
+
+ -b may optionally be specified to block the use of predefined
+ accented characters, forcing vpl2ovp to define its own
+ versions. This may be useful to secure a consistent appearance
+ in cases where a font designer does not share vpl2ovp's views
+ on where accents should be placed.
+
+ -h prints this help.

+"Syntax: vpl2vpl -d definition-file [-s shrink-factor]
+ [-c candrabindu-adjustment] [-b] vpl-file
+
+Vpl2vpl creates new TeX virtual fonts based on existing virtual
+fonts (\"input fonts\"). A successful run will read a vpl (Virtual
+Property List) file and a definition file, and will generate a new
+vpl file on standard output. The input font is assumed to adhere to
+the standard TeX encoding for text fonts unless it was created with
+the program afm2tfm, in which case it is assumed to conform to the
+encoding specified in the file dvips.enc. In either case, the name
+of the input font is assumed to be the name of the input file
+without its .vpl extension: it must conform to normal TeX
+conventions for naming fonts, as vpl2vpl attempts to draw
+conclusions from it about the kind of font it is dealing with.
+
+In the case of a non-virtual font (such as the Computer Modern
+fonts), use a pl (Property List) file, created with the standard
+utility tftopl, as the input file in place of a vpl file; vpl2vpl
+will make the necessary changes on the fly.
+
+A typical complete sequence of commands to create a new virtual
+font might therefore be
+ tftopl cmr10.tfm cmr10.pl
+ vpl2vpl -d ISO-Latin1.def cmr10.pl >cmr10_isol1.vpl
+ vptovf cmr10_isol1.vpl cmr10_isol1.vf cmr10_isol1.tfm
+for a Computer Modern font, or
+ afm2pl Times-Roman.afm rptmr.pl
+ pltotf rptmr.pl rptmr.tfm
+ vpl2vpl -d ISO-Latin1.def rptmr.pl >ptmr-isol1.vpl
+ vptovf ptmr-isol1.vpl ptmr-isol1.vf ptmr-isol1.tfm
+for a PostScript font.
+
+Another approach for a PostScript font is to use afm2tfm:
+ afm2tfm Times-Roman.afm -t dvips.enc -v ptmr rptmr
+ vpl2vpl -d ISO-Latin1.def ptmr.vpl >ptmr-isol1.vpl
+ vptovf ptmr-isol1.vpl ptmr-isol1.vf ptmr-isol1.tfm
+-- but this is now deprecated, as afm2tfm generates incorrect
+values for the heights of some characters, and this can lead to
+bad accent placing.
+
+In order to keep the whole upper half of the character set free for
+the requirements of the encoding specified in the definition file,
+certain modifications are made to input fonts following the
+dvips.enc encoding to bring them into greater conformity with the
+TeX norm. In particular, the characters dotaccent and hungarumlaut
+are placed in the positions assigned by TeX (\"5F, \"7D), not those
+enforced by dvips.enc (\"C7, \"CD). The f-ligatures, double quotes
+and dashes are also moved from the upper half of the character set
+to their normal TeX positions. As a result, the following characters
+are not found in the lower half of the character set: quotesingle,
+quotedbl, backslash, underscore, braceleft, bar, braceright. These
+characters can, however, be assigned positions in the output font if
+they are needed. (Indeed, they could all be explicitly restored to
+their dvips.enc positions if this were desired.)
+
+Options:
+
+ -d should refer to a font definition file. This file (which could
+ usefully be named, e.g., \"French.def\") should consist of
+ lines of character definitions, in the form
+ \"number\" \"character\"
+ or
+ \"number\" \"character\" \"accent\"
+ Here \"number\" represents the character's position in the new
+ encoding and may be expressed in decimal, octal or hex;
+ \"character\" names the character (e.g. \"comma\", \"eight\",
+ \"A\") or consists of the word \".notdef\" (indicating that
+ the specified number's \"slot\" in the new encoding is to be
+ empty); and \"accent\" optionally names an accent to be placed
+ on the character. In addition to the standard accents available
+ in PostScript fonts, \"underbar\" and \"underdot\" are also
+ available, as are \"under\" versions of all the normal
+ superscript accents (\"underdieresis\", \"underring\", etc.).
+ The Indian accent \"candrabindu\" may also be specified: it
+ is formed by overprinting a breve with a dotaccent. Finally,
+ \"overdot\" may be used as a synonym for \"dotaccent\".
+
+ If the character named in the \"accent\" position is not in fact
+ a valid accent character, the program interprets the definition
+ as a request for a digraph formed from the \"character\" and the
+ \"accent\". A digraph consisting of, say, \"k\" and \"h\" will be
+ indistinguishable from the letters \"k\" and \"h\" printed
+ consecutively, but the digraph \"kh\" can itself receive accents
+ like any other character: see next paragraph.
+
+ A new character (such as \"amacron\" or \"kh\") may be freely
+ used in the \"character\" position of a further definition (such
+ as \"amacron breve\" or \"kh underbar\"). There is no constraint
+ on the ordering of definitions within a definition file. The
+ definition of \"a macron\" does not have to precede that of
+ \"amacron breve\": requests for \"impossible\" characters are
+ deferred until their constituents have had a chance to come into
+ being.
+
+ \"Slots\" for which no new definition is given retain the
+ definition they have in the input font.
+
+ The definition file may also contain blank lines and comments
+ (introduced by \"\#\").
+
+ -s may optionally give the factor, expressed as a per-thousand
+ value, by which normally superscript accents (such as dieresis,
+ ring) should be shrunk when they are used as subscript accents
+ (such as underdieresis, underring). Values of around 800 may be
+ found useful.
+
+ -c may optionally give two comma-separated numerical values to
+ adjust the x and y coordinates of the dotaccent placed within a
+ breve to form the candrabindu accent. A coordinate scheme using
+ \"DESIGNUNITS R 1000\" is assumed.
+
+ -b may optionally be specified to block the use of predefined
+ accented characters, forcing vpl2vpl to define its own
+ versions. This may be useful to secure a consistent appearance
+ in cases where a font designer does not share vpl2vpl's views
+ on where accents should be placed.
+
+ -h prints this help.
