Log Message:
Update to 1.22.3:

VERSION 1.22.3
==============

Gxditview
---------

o X11 resources for `gxditview', which were previously installed in
  /usr/X11/lib/X11/app-defaults no matter which `prefix' was set, are
  now installed in appresdir=$prefix/lib/X11/app-defaults.  If
  `appresdir' is not a standard X11 resource directory, the environment
  variable XFILESEARCHPATH should be set to this path.  The standard
  default directories depends on the system `libXt'.  Common directories
  include:

   /usr/lib/X11/app-defaults
   /usr/share/X11/app-defaults
   /etc/X11/app-defaults

  Note that if the option `--with-appresdir' is passed to `configure',
  the `prefix' will not be added to `appresdir'.

Glilypond
---------

o This new preprocessor (contributed by Bernd Warken) allows embedding of
  code for GNU LilyPond (http://www.lilypond.org), a music typesetter.  The
  data gets automatically processed and embedded as EPS images.

Gperl
-----

o Bernd Warken contributed a new preprocessor to handle Perl code that can
  be evaluated and then processed by groff.

Gpinyin
-------

o Another preprocessor from Bernd Warken to pretty-print Pinyin syllables
  like `guo2wang2' as `guówáng'.

Pdfroff
-------

o The pdfroff utility script now activates its `--no-toc-relocation' option
  by default, unless a request similar to:

     .if !\n[PHASE] .tm pdfroff-option:set toc_relocation=enabled

  is invoked during input file processing; (`.if !\n[PHASE] ...' ensures
  that the effect of the `.tm' request is restricted to the document setup
  phase of processing, as pdfroff sets it to 1 or 2 in the output phase,
  but leaves it unset in the setup phase).

  The bundled `spdf.tmac' macro package, which implicitly activates
  `-mpdfmark' for `ms' macro users, ensures that TOC relocation is
  appropriately enabled, when the `.TC' macro is invoked.

Macro Packages
--------------

o The -mom macro package now has full support for eqn, pic, and tbl, as well
  as captioning and labelling of pdf images and preprocessor output.  Lists
  of Figures, Equations, and Tables can now be autogenerated.  PDF_IMAGE has
  a new FRAME option.

o A French introduction to the -me macro package has been added (file
  `meintro_fr.me').

o In -mdoc, command %C is now available, providing a city or place
  reference.

VERSION 1.22.2
==============

Tbl
---

o The character `#' can now be used as an eqn delimiter within tables.

Eqn
---

o A GNU extension

    delim on

  has been added to reactivate delimiters which have been disabled with
  `delim off'.

VERSION 1.22.1
==============

(There was no release 1.22.)

Groff
-----

o A new option `-j' has been added to call the `chem' preprocessor.

Tbl
---

o Improved line numbering support.

Macro Packages
--------------

o Support for the `refer' preprocessor has been added to the -mm macro
  package.

o In -me, the `TH' macro was changed for compatibility with line number
  support in tables.

  `bl' now works inside of blocks.

  The behaviour of centered blocks has been improved.

  Line numbering support has been improved.

o The -mom macro package has reached version 2.0, focusing on PDF output
  with gropdf (using the new `pdfmom' wrapper script).  See the file
  `version-2.html' of the -mom documentation for a list of the many changes.

o Some generic Unicode fallback characters (mainly Roman numerals) have been
  added.

Gropdf
------

o A new driver for generating PDF output directly, contributed by Deri James
  <deri@chuzzlewit.myzen.co.uk>.  Note that this driver is written in Perl,
  thus you need a working Perl installation to run this output device.

Pdfmom
------

o A new wrapper around groff that facilitates the production of PDF
  documents from files formatted with the -mom macros.

VERSION 1.21
============

Troff
-----

o The new `lsm' request specifies a macro to be invoked when leading spaces
  in an input line are encountered (which are removed then).  Number
  registers `lsn' and `lss' hold the number of removed leading spaces and
  the corresponding horizontal space, respectively.

o There is a new warning category `file', enabled by default.  The `mso'
  request emits warnings in this category when the requested macro file does
  not exist.

o The new `class' request assigns a short name to a set of characters
  which can be referred to in the `cflags' request.  This is especially
  useful to control line-breaking and hyphenation rules in CJK languages.

o Three new values for the `cflags' request have been added, which are
  needed for proper CJK support.

    128  prohibit before but allow break after character
    256  prohibit after but allow break before character
    512  allow break before and after character

Tbl
---

o A new global option `nowarn' suppresses warnings if tables are longer than
  the current line width.

Afmtodit
--------

o New option `-o' to specify the name of the output file.

Macro Packages
--------------

o A new macro `%U' has been added to the mdoc package to indicate a URL
  reference within an .Rs/.Re environment.

o Rudimentary support for the Japanese script has been added, most suitable
  for man page handling as output by grotty.  The file `ja.tmac' contains
  the necessary setup to allow line breaks before and after CJK characters
  (with proper exceptions).  Note, however, that no inter-character spacing
  is implemented yet -- this usually causes many warnings about bad line
  breaks.
