+
+	* tmac/groff_tmac.man: Fix typo.
+
+2001-02-16  Werner LEMBERG  <wl@gnu.org>
+
+	Fixing a bug which prevented proper end-of-sentence recognition
+	between an `unformatted' box and the following text.  As a
+	consequence, vertical line distances are no longer preserved in
+	boxes after a call to `.unformat' -- because boxes aren't
+	line-oriented (contrary to diversions), this doesn't make sense
+	anyway.
+
+	* src/roff/troff/node.cc (*node::set_unformat_flag): Add return
+	value.
+	(vertical_size_node::set_unformat_flag): New method.

+
+	* src/roff/troff/troff.man, NEWS, man/groff.man: Improved
+	documentation of `asciify' and `unformat' requests.
+
+2001-02-13  Werner LEMBERG  <wl@gnu.org>
+
+	Redesigned the `unformat' request.  It is no longer connected with
+	`asciify' but rather uses new `reread()' methods if the `unformat'
+	flag is set.  Additionally, the handling of space characters after
+	unformatting has been fixed so that they retain their width.
+
+	* src/roff/troff/node.h (width_list): New structure to store
+	original widths of spaces.
+	(node): Added `unformat' member.
+	Replaced `num_spaces' variable with `orig_width' list.
+	* src/roff/troff/node.cc (*node::asciify,
+	asciify_reverse_node_list): Removed `unformat_only' flag and related
+	code.
+	(word_space_node::asciify, word_space_node::word_space_node): Use
+	`orig_width'.
+	(word_space_node::~word_space_node): New destructor.
+	(word_space_node::copy): Updated to handle `orig_width'.
+	(hmotion_node::copy, unbreakable_space_node::copy): Updated.
+	(*node::merge_space): Update `orig_width' list if necessary.
+	(*node::set_unformat_flag): New methods to set the `unformat' flag.
+	* src/roff/troff/enc.cc (environment::space_newline): Use
+	`width_list'.
+	(environment::space): Added method to handle space width and
+	sentence space width as parameters.  Use `width_list'.
+	(environment::make_tab_node): Updated.
+	* src/roff/troff/env.h: Updated.
+	* src/roff/troff/input.cc (word_space_node::reread,
+	unbreakable_space_node::reread, hmotion_node::reread): New methods
+	to handle nodes specially if `unformat' flag is set.
+	(do_asciify_macro): Renamed back to ...
+	(asciify_macro): This.
+	(unformat_macro): New implementation to simply set the `unformat'
+	flag.
+
+	* MORE.STUFF: Added more info about deroff.
+
+2001-02-08  Werner LEMBERG  <wl@gnu.org>
+
+	* src/roff/troff/node.h (unbreakable_space_node, hmotion_node,
+	space_char_hmotion_node, overstrike_node): Add `get_hyphen_list()'
+	and `add_self()' methods to avoid hyphenation.  For example, the
+	hyphen list for `foo\0\0bar' was `foobar', causing insertion of a
+	soft hyphen after `foo'.  Now the hyphen list is correctly
+	`foo<ignore><ignore>bar'.
+
+2001-02-05  Yoshiteru Kageyama  <yt-kage@cb3.so-net.ne.jp>
+
+	* tmac/groff_tmac.man: Fix `BIR' macro.

+	(space_node::asciify): Handle `was_escape_colon'.
+	* NEWS, src/roff/troff/troff.man, man/groff.man: Document it.
+
+	Handle `\~' similar to other comparable requests.
+
+	* src/roff/troff/input.cc (process_input_stack): Remove now obsolete
+	label.
+	(token::next): Move creation of an unbreakable_space_node to...
+	(token::add_to_node_list): Here.
+
+	Fix a bug which sometimes prevented hyphenation of words connected
+	with `\~' or `\ ' (and other escape sequences handled as
+	TOKEN_NODE).  This also fixes a hyphenation problem with boxes
+	(after a call to the `unformat' request).
+
+	* src/roff/troff/env.h (environment::possibly_break_line,
+	environment::hyphenate_line): Introducing `start_here' parameter.
+	* src/roff/troff/env.cc (environment::space_newline,
+	environment::space): Use it.
+	(environment::possibly_break_line, environment::hyphenate_line):
+	Implement it.

+	if `unformat_only' is active.
+
+2001-01-30  Werner LEMBERG  <wl@gnu.org>
+
+	Implemented new read-only number register `.linetabs' which
+	returns 1 if in line-tabs mode, 0 otherwise.
+
+	* src/roff/troff/env.h (environment): Add get_line_tabs() member.
+	* src/roff/troff/env.cc (get_line_tabs): New function.
+	(init_env_requests): Use it.
+	* NEWS, src/roff/troff/troff.man, man/groff.man: Document it.
+
+	* VERSION, REVISION: Changing to 1.17.0.
+
+2001-01-28  Werner LEMBERG  <wl@gnu.org>
+
+	Fixed a bug which prevented hyphenation of words which are finished
+	with `\)'.
+
+	* src/roff/troff/token.h (token): Add enum type
+	`TOKEN_TRANSPARENT_DUMMY' and method `transparent_dummy()'.
+	* src/roff/troff/input.cc (token::next, token::description,

+
+2001-01-25  Werner LEMBERG  <wl@gnu.org>
+
+	Adding the `linetabs' request.  If set, tab distances are not
+	computed relative to the input line but relative to the output line.
+
+	* src/roff/troff/env.h (environment): New member `line_tabs'.
+	* src/roff/troff/env.cc (line_tabs_request): Implement request.
+	(environment::environment, environment::copy): Updated.
+	(environment::distance_to_next_tab): Use `line_tabs'.
+	(init_env_requests): Register request.
+	* src/roff/troff/troff.man, man/groff.man, NEWS: Document it.  Other
+	fixes.
+
+2001-01-24  Werner LEMBERG  <wl@gnu.org>
+
+	Introducing a new read-only register `.int' which is set to a
+	positive value if the last output line is interrupted (i.e., if it

+	* node.cc (hmotion_node::copy, hmotion_node::asciify): Use it.
+
+	Added new request `unformat' which will, contrary to `asciify',
+	preserve font information after unformatting (i.e., only nodes
+	dealing with horizontal space are converted back to input
+	characters).
+
+	* input.cc (asciify_macro): Renamed to ...
+	(do_asciify_macro): this, having a new parameter `unformat_only'.

+
+	First cut of the new html device driver.  Changes to pre-html and
+	the new grohtml are too numerous to be documented here.
+
+	Stuff related to `html' has been renamed to `html-old' and `html2'
+	stuff has been renamed to `html' (including directories).  The new
+	html device driver is therefore invoked as `-Thtml'.
+
+	Added new `\O' escape to suppress output (needed by html driver).
+
+	Added functions and code to pass info about input-level commands
+	(`.in', `.fl', etc.) to html driver.
+
+	Three new functions (.html-begin, .html-end, and .html-image) for
+	better html handling: `html-begin' will execute the remaining line
+	if at the outermost nesting level, increasing an internal counter.
+	`html-end' does the same but decreases the internal counter.
+	`html_image' puts its arguments into a special node (suppress_node)
+	to define an image region.
+
+	The `output' request has been removed.

+From the web page:

 This file describes recent user-visible changes in groff.  Bug fixes
 are not described.  There are more details in the man pages.
 
+Groff
+-----
+
+o `-mFOO' will now search first for `FOO.tmac' and then for `tmac.FOO'.  The
+  old behaviour has been changed to overcome problems with platforms which
+  have an 8+3 file name limit, and platforms which have other versions of
+  troff installed also. Additionally, all macro files have been renamed
+  using the latter scheme to avoid 8+3 name clashes.
+
+o The new environment variable GROFF_BIN_PATH will be checked for programs
+  groff is calling (preprocessors, troff, and output devices) before PATH.
+  If not set, it defaults to the directory where the groff binary is
+  located.  Previously, it was PATH only.  The nroff script will only use
+  GROFF_BIN_PATH to find the groff binary but passes both the GROFF_BIN_PATH
+  and PATH environment variable to groff.
+
+Troff
+-----
+
+o The mdoc package has been completely rewritten, using the full power of
+  GNU troff to remove limitations of Unix troff (which is no longer
+  supported).  Most important changes are:
+

+
+  `groff_mdoc.man' replaces `groff_mdoc.samples.man'; it now completely
+  documents the mdoc package.
+
+  Great care has been taken to assure backwards compatibility.  If you
+  encounter any abnormal results, please report them to bug-groff@gnu.org.
+
+o A new command line option for the `man' macros (similar to the `mdoc'
+  package has been implemented: `-rcR=1' (now the default in nroff mode) will
+  produce one single, very long page instead of multiple pages.  `-rcR=0'
+  will deactivate it.
+
+o The `return' request has been added to return immediately from a macro.
+
+o A new request `nop' (no operation) has been added which is similar to
+  `if 1'.  For example,
+
+    .if t \{\
+    Hallo!
+    .\}
+
+  can now be written as
+
+    .if t \{\
+    .  nop Hallo!
+    .\}
+
+o `box' and `boxa' are two new requests which behave similarly to `di' and
+  `da' but don't include a partially filled line (which is restored after
+  ending the diversion).
+
+o The `asciify' request has been extended to `unformat' space characters
+  and some other escape sequences also.
+
+  `\ ' will no longer be unformatted as a space but remains an unpaddable,
+  unbreakable space character.
+
+o The new `unformat' request is similar to `asciify' but only handles space
+  characters and tabs specially if the diversion is reread, retaining font
+  information.  This makes it possible to reformat diversions; for example
+  the following
+
+    .ll 3i
+    .
+    a01 a02 a03 a04 a05 a06 a07 a08 a09 a10.
+    .
+    .box box1
+    .ev 1
+    .nf
+    \f[B]b01 b02 b03 b04 b05 b06 b07 b08 b09 b10.\f[P]
+    .br
+    .ev
+    .box
+    .
+    c01 c02 c03 c04 c05 c06 c07 c08 c09 c10.
+    .
+    .unformat box1
+    .box1
+
+  gives
+
+    a01  a02  a03  a04 a05 a06 a07
+    a08 a09 a10.  c01 c02 c03  c04
+    c05  c06 c07 c08 c09 c10.  b01
+    b02 b03 b04 b05  b06  b07  b08
+    b09 b10.
+
+  Without the `unformat' request, space characters are converted to word
+  space nodes which are no longer stretchable, and the result would be
+
+    a01  a02  a03  a04 a05 a06 a07
+    a08 a09 a10.  c01 c02 c03  c04
+    c05  c06 c07 c08 c09 c10.  b01
+    b02 b03 b04 b05 b06 b07 b08
+    b09 b10.
+
+o The new request `linetabs' controls the `line-tabs' mode.  In line-tabs
+  mode, tab distances are computed relative to the (current) output line.
+  Otherwise they are taken relative to the input line.  For example, the
+  following
+
+    .ds x a\t\c
+    .ds y b\t\c
+    .ds z c
+    .ta 1i 3i
+    \*x
+    \*y
+    \*z
+
+  yields
+
+    a         b         c
+
+  In line-tabs mode, the same code gives
+
+    a         b                   c
+
+  The new read-only number register `.linetabs' returns 1 if in line-tabs
+  mode, and 0 otherwise.
+
+o Two new requests `tm1' and `tmc' have been added to improve writing
+  messages to the terminal.  `tm1' is similar to `tm' but allows leading
+  whitespace.  `tmc' is similar to `tm1' but doesn't emit a final newline.
+
+o A new request `dei' (define indirect) has been added.  The first and
+  second parameter of `dei' are taken from string registers rather than
+  directly; this very special request is needed to make `trace.tmac'
+  independent from the escape character (which might even be disabled).
+
+o It is now possible to save and restore the escape character with two new
+  requests `ecs' and `ecr'.
+
+o The new escape sequence \B'...' is an analogon to `\A': If the string
+  within the delimiters is a valid numeric expression, return character `1',
+  and `0' otherwise.
+
+o The new escape sequence `\:' inserts a zero-width break point.  This is
+  similar to `\%' but without a soft hyphen character.
+
+o The `tr' request can now map characters onto `\~'.
+
+o Calling the `fam' request without an argument switches back to the
+  previous font family.
+
+o The new read-only register `.int' is set to a positive value if the last
+  output line is interrupted (i.e., if it contains `\c').
+
+o The `writem' request is not new, but hasn't been documented before.  This
+  is similar to `write' but instead of a string the contents of a given
+  macro or string is written to a stream.
+
+o The read/write number register `hp' to get/set the current horizontal
+  position relative to the input line isn't new but hasn't been documented
+  properly before.
+
+o `\X' and `\Y' are no transparent for end-of-sentence recognition.
+
+o The `cu' request in nroff mode now works as documented (i.e., it does
+  underline spaces also).
+
+Nroff
+-----
+
+Option -v shows the version number.
+
+Grog
+----
+
+o The grog script will now work in non-compatibility mode also (which is the
+  default).  As usual, use the `-C' option to activate compatibility mode.
+
+o Option -v shows the version number.
+
+Grops
+-----
+
+A new option `-P' resp. a new environment variable `GROPS_PROLOGUE' has been
+added to select a different prologue file.
+
+The effect of the former `-mpsnew' option to access more Type 1 characters
+is now the default and no longer available.  To get the old behaviour (i.e.,
+emulation of some glyphs by composition) use `-mpsold'.
+
+Miscellaneous
+-------------
+
+o For security reasons the following changes have been done:
+
+  . The tmac.safer file has been replaced with a built-in solution; .open,
+    .opena, .pso, .sy, and .pi are completely disabled in safer mode (which
+    is the default); to enable these requests the `-U' command line flag
+    must be used.
+
+  . Files specified with the .mso request or given with the `-m' command
+    line option, and hyphenation patterns loaded with `.hpf' are no longer
+    searched in the current directory by default (besides the usual tmac
+    path). Instead, the home directory is used. To add the current
+    directory, either use the `-U' or `-M' command line option or set the
+    GROFF_TMAC_PATH environment variable to an appropriate value.
+
+  . troffrc, troffrc-end, and eqnrc are neither searched in the current nor
+    in the home directory (even if -U is given).  Use -M or GROFF_TMAC_PATH
+    to change that.
+
+  . Similarly, the current directory is no longer part of the font path.
+    Use the `-F' command line option or the GROFF_FONT_PATH environment
+    variable if you really need the current directory.
+
+o groff will now install its data files into
+  /usr/local/share/groff/<version> by default, following the GNU standard.
+  Additionally, a local tmac directory (by default
+  /usr/local/share/groff/site-tmac) will be scanned before the standard tmac
+  directory.  Wrapper files for system-specific macro packages (if
+  necessary) are put into /usr/local/lib/groff/site-tmac; this directory
+  will be searched before the local tmac directory.
+
+o All programs now have option `-v' to show the version number; they will
+  exit immediately afterwards, following the GNU standards.  Additionally,
+  `--version' and `--help' have been added, doing the obvious actions.
+

+	* New Changelog-format, it will show changes better.
+	  Easier for other to use. (Somehow I didn't really

+
+	* version 2.0
+	* Had to do something about my version numbering.
+	  The main CVS archive was not in sync with mine.
+	  So, now it is 2.0. :-)
+
+Sat Jun 17 23:00:00 2000 Eli Zaretskii (eliz@is.elta.co.il)

+	* Makefile.sim (.man.n): Replace `;' with `|', since DOS/Windows
+	  path lists use the semicolon as a separator.
+
+Sun Jun 4 21:39:00 2000 Kaneda Hiroshi (vanitas at ma3.seikyou.ne.jp)
+
+	* Fixing a lot of typos in groff_mm.man
+
+Sun Jan 30 22:52:20 2000 Jörgen Hägg (jh at axis.com)
+
+	* version 1.34
+	* Changed the version number in the CVS repository
+	* MC had a bug in column calculation, (thanks to T. Kurt Bond)
+
+Fri Sep 3 07:33:14 1999 Jörgen Hägg (jh at axis.com)
+
+	* version 1.33
+	* At last! I finally tracked down the PGFORM bug!
+	  It didn't setup the @pl, @ll and @po as it should, now it does.
+	* mgm_ref/mgm_roff renamed to mmroff [-x]
+	* fixed y2k-bug in \*[DT]
+	* \n[cov*year] removed, hope noone used that.
+	* ISODATE added with Iso as command line flag
+		(iso-date suggested by Paul Eggert)
+	* Added ISODATE to tmac.mse and removed local settings
+	  of new-date.
+	* INITI syntax changed and enhanced. Index processing is now
+	  done with mmroff.
+	* A few examples has been added, new subdirectory 'examples'.
+	* Fixed bug with SETR, header references are now only saved
+	  when Ref > 0
+	* Problem with register H1h fixed
+	* Added test for missing abstract in 4.MT
+	* Updated Makefile.sub, using tmac_m_prefix.
+
+Mon Mar 15 22:22:42 1999 Jörgen Hägg (jh at axis.com)
+
+	* OK, let's release this as a beta, 1.33 will be better. :-)
+	* version 1.32
+	* fixed .el-error
+	* Added number variable Hss
+	* Changed Hps1 and Hps2 to units
+	* added hd*h1-text to be used in user defined macro TP.
+	* -U needed for SETR (I really need 'mv', 'echo', 'rm'
+	  and 'test' builtin!)
+	* Rewritten the reference system, SETR now prints to stderr
+	  if the number register Qrf > 0. Store in the filename
+	  that is the argument to .INITR
+	  The old behaviour is returned if number register Initr > 0.
+	* Fixed bug with List of XXXX, long lines messed up the result.
+	* added number register H1dot.
+	* added string variable H1txt
+	* added string variable Tcst
+	* added number register Dsp.
+	* added alias APPX for user-defined appendix title.
+	* added string variable Apptxt
+	* added H1h for use in TP in headers
+	* added macro EPIC
+	* added macro PIC (safe replacement for PSPIC)
+	* fixed Hps-bug, should be 1, not 1v.
+	* fixed bug with APPSK, variable not set.
+
+Wed Feb 4 15:46:04 1998 Jörgen Hägg (jh at axis.se)
+
+	* version 1.31
+	* .LI will now honor a space mark.
+	* Another fix for .AU to let it be used without arguments.
+	* uninitialized eq*label fixed
+
+Fri Sep 6 07:13:07 1996 Jörgen Hägg (jh at axis.se)
+
+	* version 1.30
+	* This is more like a beta-release, bugs might pop up. :-)
+	* last line in TOC was not correctly terminated (missing .br)
+	* changed the indentation for displays, it will now
+	  indent to the current indent, not the one at the definition
+	  of the display.
+	* Equation marks should now work better, indentation also.
+	* included these bug fixes from Larry Jones:
+	*   The documentation for the argument to .AS was incorrect for MT 4.
+	*   \*(EM should be a double-dash for nroff.
+	*   \nS is in points, not units.
+	*   If \nO isn't set, the default page offset should be .75i for nroff
+		and .963i for troff.
+	*   .S D should set the point size to \nS, not 10.
+	*   .S was setting the vertical spacing based on the old point size
+		instead of the new point size.
+	*   Got rid of a spurrious .br that prevented run-in headings from
+		working.
+	*   Reset the .SP counters in pg@header so that spacing on one page
+		won't affect spacing on subsequent pages.
+	*   Allow .AU and .AF with no arguments (real mm does, even though it
+		isn't documented).
+	*   Do .init@reset first thing to initialize the default environment.
+	*   For MT 4, the title should be 4 points larger than the default size,
+		not 12 point.
+	*   The cover environment needs to be initialized.
+	*   Printing the abstract on the first page needs to be controlled by
+		the .AS argument.
+	*   Heading eject should be suppressed if the heading immediately
+		follows the first page stuff (title, author, etc.).
+	*   support for table of contents numbering style (.nr Oc)
+	*   changes the troff empty line height from .25v to .5v
+	*   fixed section page numbering
+	*   fixed a really nasty bug in footnotes that could cause you
+		to lose the page footer completely if the very first
+		footnote on the page occurred at just the wrong place
+
+
+Wed May 15 07:39:32 1996 Jörgen Hägg (jh at axis.se)
+
+	* version 1.29
+	* Syntax and scaling errror fixed, (thanks to Frazer Williams)
+	* DF/DE will now do a line-break before printing the display.
+	* Updated the manual for TB,FG,EX and EC.
+	* Added support for the ms- (and mgs-)macro .IX
+	* Added indexmacro IX, INITI, IND and INDP, support for
+	  TXIND, TYIND and TZIND.

+
+Beware!
+This may be old information. Trust only the source. :-)
+
+Implementation notes. (Or how to make your own national mm)
+
+Different commands:
+
+COVER [arg]
+MT [arg [addressee]]
+The arg is part of a filename in mm/*.MT or mm/*.cov.
+This file is read when the macro is executed. Therefore it must be
+put before any text output.
+In each file there are definitions of all extra macros needed for the
+cover sheet. MT files is only for compatibility reasons, and has several
+limits due to that it don't know when the cover starts, and cannot
+change sizes. Use COVER for new coversheet macros.
+
+But with MT it is possible to write all of the AT&T covers.
+An example can be found in mm/0.MT.
+
+When writing a new cover using COVER, have in mind that the cover
+should print the page with the COVEND macro. This macro
+should be defined by the new macrofile.
+
+Here is a part of ms.cov:
+> .\"-----------------
+> .de COVEND
+> .sp |4.2c
+> .cov@print-title
+> .cov@print-authors
+> .cov@print-firm
+> .cov@print-abstract
+> .cov@print-date
+This is important, since COVER disables the page header.
+> .pg@enable-top-trap
+Should begin with page one (normally).
+> .bp 1

+$Id: README,v 2.1 2000/11/17 04:27:03 jhaegg Exp $
+
+This is mgm, a macro package for groff.
+
+It is supposed to be compatible with the DWB mm macros,
+and has several extensions.
+
+Send bug reports to jh@axis.com with a description of the problem
+and a sample of text which reproduces the error.
+
+Don't forget to mention the version of mgm (look in the beginning
+of m.tmac) and the version of groff.
+
+Any new ideas or improvements are welcome.
+
+Newest version is available here or at the groff CVS repository.
+ftp://ftp.axis.se/pub/groff/mm<something>.gz
+
+You can install mgm as a separate package without the configure in groff
+with the following command:
+
+make -f Makefile.sim install
+
+This README should be bigger :-)
+
+/Jörgen Hägg
+
+Thanks to everyone who have sent me bug-reports and fixes.
+
+
+Yes, my version numbering differs from the groff CVS, but I
+like mine better. :-)
+
+More likely, I'm too lazy to change it, but someday I'll
+try to sync them...
+The step to 2.0 is an attempt, let's see if it works.

+.SH SYNOPSIS
+.B groff
+.B \-m@TMAC_M_PREFIX@m
+[
+.IR options .\|.\|.
+]
+[
+.IR files .\|.\|.
+]
+.SH DESCRIPTION
+The groff mm macros are intended to be compatible with the DWB mm macros
+with the following limitations:
+.TP
+.B \(bu
+no Bell Labs localisms implemented.
+.TP
+.B \(bu
+the macros OK and PM is not implemented.
+.TP
+.B \(bu
+groff mm does not support cut marks
+.LP
+\fBm@TMAC_M_PREFIX@m\fP is intended to be international. Therefore it is 
+possible to write short national macrofiles which change all
+english text to the preferred language. Use \fBm@TMAC_M_PREFIX@mse\fP as an example.
+.\"########################################################################
+.LP
+A file called \fBlocale\fP or \fIlang\fP\fB_locale\fP is read
+after the initiation of the global variables. It is therefore
+possible to localize the macros with companyname and so on.
+.sp
+In this manual square brackets is used to show optional arguments.
+.sp 3
+\fBNumber registers and strings\fP
+.br
+Many macros can be controlled by number registers and strings.
+A number register is assigned with the \fBnr\fP command:
+.br
+\fB\&.nr\fP \fIXXX\fP \fI[+-]n [i]\fP
+.br
+\fBXXX\fP is the name of the register, \fBn\fP is the value to
+be assigned, and \fBi\fP is increment value for auto-increment.
+\fBn\fP can have a plus or minus sign as prefix if an increment
+or decrement of the current value is wanted. (Auto-increment or decrement
+occurs if the number register is used with a plus or minus sign,
+\fB\en+[XXX]\fP or \fB\en-[XXX]\fP.)
+.sp
+Strings is defined with \fBds\fP.
+.br
+\fB\&.ds\fP \fIYYY string\fP
+.br
+The string is assigned everything to the end of the line, even blanks.
+Initial blanks in \fIstring\fP should be prefixed with
+a double-quote. (Strings are used in the text as \fB\e*[YYY]\fP.)
+.sp
+\fBSpecial formatting of number registers\fP
+.br
+A number register is printed with normal digits if no format has been
+given.
+Set the format with \fBaf\fP:
+.br
+\fB\&.af\fP \fIR c\fP
+.br
+\fIR\fP is the name of the register, \fIc\fP is the format.

+.TP
+.B "COVER [arg]"
+\&\fBCOVER\fP begins a coversheet definition. It is important
+that \fB.COVER\fP appears before any normal text.

+.B "H level [heading-text [heading-suffix]]"
+Numbered section heading.
+Section headers can have a level between 1 and 7, level 1 is the
+top level. The text is given in \fIheading-text\fP, and must be
+surrounded by double quotes if it contains spaces.
+\fBHeading-suffix\fP is added to the header in the text but not in

+All marks are concatenated before printing. To avoid this, set
+number register \fBHt\fP to 1. That will only print the current
+heading counter at each heading.

+.sp
+\fIPad\fP and \fImark-indent\fP controls where to put the mark.
+The mark is placed within the mark area, and \fImark-indent\fP
+sets the number of spaces before this area. It is normally 0.
+The mark area ends where the text begins. The start of the text
+is still controlled by \fItext-indent\fP.
+.sp
+The mark is left justified whitin the mark area if \fIpad\fP is 0.
+If \fIpad\fP is greater than 0, then \fImark-indent\fP is ignored, and
+the mark is placed \fIpad\fP spaces before the text.
+This will right justify the mark.
+.sp
+If \fItype\fP is 0 the list will have either a hanging indent or, if
+argument \fImark\fP is given, the string \fImark\fP as mark.

+Do not eject page after the list.
+.T2 2
+Do not eject page before the list.
+.T2 3
+Do not eject page before and after the list.
+.in
+The reference items will be separated by a blank line.
+Setting number register \fBLs\fP to 0 will suppress the line.
+.sp
+The string \fBRp\fP contains the reference page title and
+is normally set to \fIREFERENCES\fP.
+.TP
+.B "RS [string-name]"
+\fBRS\fP begins an automatically numbered reference definition.
+Put the string \fB\e*(Rf\fP where the reference mark
+should be and write the reference between \fBRS\fP/\fBRF\fP
+at next new line after the reference mark. The reference number
+is stored in number register \fB:R\fP.
+If \fIstring-name\fP is given, a string with that name
+will be defined and contain the current reference mark.
+The string can be referenced as \fB\e*[\fIstring-name\fP]\fP later in
+the text.
+.TP
+.B "S [size [spacing]]"
+Set point size and vertical spacing. If any argument is equal 'P', then
+the previous value is used. A 'C' means current value, and 'D' default value.
+If '+' or '-' is used before the value, then increment or decrement of
+the current value will be done.
+.TP
+.B "SA [arg]"
+Set right-margin justification.
+Justification is normally turned on.
+No argumenent or \fB0\fP turns off justification, a \fB1\fP turns on
+justification.
+.TP
+.B "SETR refname [string]"
+Remember the current header and page-number as \fIrefname\fP.
+Saves \fIstring\fP if \fIstring\fP is defined. \fIstring\fP is retrieved
+with \fB.GETST\fP.
+See \fBINITR\fP.
+.TP
+.B "SG [arg [1]]"
+Signature line. Prints the authors name(s) after the formal closing.
+The argument will be appended to the reference data, printed
+at either the first or last author. The reference data is the location,
+department and initials specified with \fB.AU\fP.
+It will be printed at the first author if the second argument is given,
+otherwise at the last.
+No reference data will be printed if the author(s) is specifed
+thru \fB.WA\fP/\fB.WE\fP.
+See \fBINTERNALS\fP.
+.TP
+.B "SK [pages]"
+Skip pages.
+If \fIpages\fP is \fB0\fP or omitted, a skip to the next page
+will occur unless it is already at the top of a page.
+Otherwise it will skip \fIpages\fP pages.
+.TP
+.B "SM string1 [string2 [string3]]"
+Make a string smaller.
+If \fIstring2\fP is given, \fIstring1\fP will be smaller and \fIstring2\fP
+normal, concatenated with \fIstring1\fP. With three argument, all is
+concatenated, but only \fIstring2\fP is made smaller.
+.TP
+.B "SP [lines]"
+Space vertically. \fIlines\fP can have any scalingfactor, like \fI3i\fP or
+\fI8v\fP. Several \fBSP\fP in a line will only produce the
+maximum number of lines, not the sum. \fBSP\fP will also be ignored
+until the first textline in a page. Add a \fB\e&\fP before \fBSP\fP
+to avoid this.
+.TP
+.B TAB
+reset tabs to every 5n. Normally used to reset any previous tabpositions.
+.TP
+.B "TB [title [override [flag [refname]]]]"
+Table title, arguments are the same as for \fBEC\fP.
+\fBTB\fP uses the number register \fBTb\fP as counter.
+The string \fBLt\fP controls the title of the
+List of Tables, default is \fILIST OF TABLES\fP.
+The List of Tables will only be printed if number register \fBLt\fP
+is 1, default 1.
+The string \fBLitb\fP contains the word \fITABLE\fP, wich
+is printed before the number.
+.br
+Special handling of the title will occur if
+\fBTB\fP is used inside \fBDS\fP/\fBDE\fP, it will not be
+affected by the format of \fBDS\fP.
+.TP
+.B "TC [slevel [spacing [tlevel [tab [h1 [h2 [h3 [h4 [h5]]]]]]]]]"
+Table of contents.
+This macro is normally used at the last line of the document.
+It generates a table of contents with headings up to the level
+controlled by number register \fBCl\fP. Note that \fBCl\fP controls
+the saving of headings, it has nothing to do with \fBTC\fP.
+Headings with level less than or equal to \fIslevel\fP will get
+\fIspacing\fP number of lines before them.
+Headings with level less than or equal to \fItlevel\fP will have
+their page numbers right justified with dots or spaces separating
+the text and the page number. Spaces is used if \fItab\fP
+is greater than zero, otherwise dots.
+Other headings will have the
+page number directly at the end of the heading text (\fIragged right\fP).
+.sp
+The rest of the arguments will be printed, centered, before the
+table of contents.
+.sp
+The user-defined macros \fBTX\fP and \fBTY\fP are used if \fBTC\fP is called
+with at most four arguments. \fBTX\fP is called before the printing
+of \fICONTENTS\fP, and \fBTY\fP is called instead of printing \fICONTENTS\fP.
+.sp
+Equivalent macros can be defined for list of figures, tables, equations
+and excibits by defining \fBTXxx\fP or \fBTYxx\fP, where \fBxx\fP
+is \fBFg\fP, \fBTB\fP, \fBEC\fP or \fBEX\fP.
+.sp
+String \fBCi\fP can be set to control the indentations for each heading-level.
+It must be scaled, like \fB.ds\ Ci\ .25i\ .5i\ .75i\ 1i\ 1i\fP.
+The indentation is normally controlled by the maxlength of headings
+in each level.
+.sp
+All texts can be redefined, new stringvariables 
+\fILifg\fP, \fILitb\fP, \fILiex\fP, \fILiec\fP and \fILicon\fP contain
