+2006.11.06 - GNU nano 2.0.0 does its little dance.  This release adds
+		documentation updates and a few cosmetic tweaks.
+			For those who haven't been following nano 1.3
+		development, there are a ton of new features, including
+		support for UTF-8, moving to a specified line and column
+		instead of just a line, improved color syntax
+		highlighting, inserting previously untypeable characters
+		using "Verbatim Input" mode, and copying text into the
+		cutbuffer without cutting it.  There are also fixes for
+		some long-standing bugs, such as the "NumLock glitch"
+		from nano 1.2.x, and the inability to unjustify text
+		after resizing.  Finally, there are also a ton of
+		translation updates and new translations, as well as new
+		color syntaxes.  See the UPGRADE file for more
+		information, and enjoy the new stable release.
+
+2006.10.25 - GNU nano 1.9.99pre3 learns to appreciate life.  This
+		release fixes a bug where the screen sometimes wouldn't
+		be updated properly after copying text into the
+		cutbuffer, fixes a potential warning while compiling,
+		and fixes a few other minor inconsistencies.  Have fun.
+
+2006.10.02 - GNU nano 1.9.99pre2 crosses the threshold.  This release
+		fixes a few more bugs: cursor positioning after leaving
+		the statusbar prompt has been fixed, and verbatim input
+		at the statusbar prompt now properly handles newlines.
+		Enjoy.
+
+2006.08.29 - GNU nano 1.9.99pre1 passes through the flames.  This
+		release fixes various bugs in the last version: the
+		mouse support properly ignores everything except clicks
+		of the left mouse button; the statusbar is now blanked
+		properly when it should be; indenting and unindenting
+		operate on the current line when the mark is off; nano
+		should build on Tru64, NetBSD, and other systems that
+		use termcap instead of terminfo in their curses
+		libraries; the built-in file browser now properly
+		navigates file lists that take up only one row; the
+		cursor position is now completely restored after
+		inserting a file into the current buffer, and after
+		inserting the output of a command into a new buffer; the
+		^X shortcut at the search prompt has been removed, as
+		official Pico doesn't include it and it's too easily
+		confused with Exit; the screen is updated properly after
+		scrolling a line without moving the cursor; the keyboard
+		input routines behave more consistently; and so on.
+		Have fun with it.
+
+2006.06.26 - GNU nano 1.3.12 escapes the darkness.  This release
+		contains the last new features that nano will have
+		before 2.0: copying text into the cutbuffer without
+		cutting it, indenting lines of marked text with a single
+		keystroke, reworked help text that should be easier for
+		new users, searching for filenames in the file browser,
+		the ability to include color regexes in files separate
+		from nanorc files, etc.  It also contains many bugfixes.
+		Text can now be unjustified after justifying it and
+		resizing the window; the screen is now cleared when
+		suspending; the "default" color syntax is now handled
+		properly at all times; lines of text containing tabs are
+		now wrapped at the right place; double-column characters
+		are now properly displayed when past the right edge of
+		the screen; invalid multi-line color regexes are now
+		ignored; and so on.  Enjoy.
+
+2006.03.30 - GNU nano 1.3.11 awakens from its fever dream.  This release
+		focuses mostly on bugfixes, which include better
+		handling of the cursor at the statusbar prompt, support
+		for certain combinations of Shift and keypad keys in
+		both normal and --rebind-keypad mode, a fix for a minor
+		display problem after some searches, a real fix for a
+		long-standing segfault when displaying overly long
+		lines, and a real fix for nano's not hanging up properly
+		in xterm under certain circumstances.  There are also
+		several new features, such as the ability to set the
+		characters used as brackets when searching for matching
+		brackets, and tab completion of directories at the "Go
+		To Directory" prompt.  Have fun.
+
+2005.12.23 - GNU nano 1.3.10 rises to the surface.  This release
+		contains several new features as well as fixes for
+		several longstanding bugs.  The former include the
+		ability to scroll up or down single lines without
+		scrolling the cursor, reworked bracket searching code
+		that doesn't require regular expression support,
+		reworked command execution code that uses $SHELL if
+		available instead of hardcoding "/bin/sh", and the
+		ability to no longer add newlines to files that don't
+		end in them via the -L/--nonewlines option.  The latter
+		include fixes to the statusbar prompt so that mouse
+		clicks work properly on it, fixes to the Yes/No/All
+		prompt so that mouse clicks on it work properly when
+		-O/--morespace is used, and fixes to the resize handling
+		so that nano dies properly when the terminal is too
+		small to display a prompt.  Enjoy.
+
+2005.10.23 - GNU nano 1.3.9 breaks through the wall.  This release
+		includes major enhancements as well as bugfixes.  The
+		enhancements include better handling of invalid UTF-8,
+		expansion of the word count option to also count lines
+		and characters in the file or selection, more efficient
+		screen update routines, a readded -K/--rebindkeypad
+		option to work around numeric keypad problems on
+		terminals that don't show the usual NumLock glitch, a
+		new -W/--wordbounds option to properly detect words
+		containing punctuation when moving among them, and
+		massive improvements to the color code such as handling
+		of unspecified foreground colors, more efficient memory
+		usage for color regexes, and new reserved syntaxes
+		"default" and "none".  The bugfixes include fixes for
+		the rewritten history code, fixes for potential line
+		numbering problems on 64-bit platforms, fixes for a few
+		long-standing minor display problems, a fix for erroneous
+		hangups occurring while waiting for input, and a fix for
+		a segfault when displaying certain overly long lines.
+		Have fun with it.
+
+2005.06.30 - GNU nano 1.3.8 floats at its own level.  This release
+		contains several new features.  Among other things, you
+		can now move to a specified column number as well as
+		line number within a file, file backups saved in a
+		backup directory will have unique names, the search and
+		replace history routines should work more consistently,
+		you can get a word count by pressing Meta-D at the edit
+		window, and there's a new -E/--tabstospaces option to
+		convert all typed tabs to spaces (--backupdir's short
+		option has been changed to -C).  In terms of bugfixes,
+		this release contains fixes for minor problems with
+		screen updates, UTF-8 display, and flow control; a fix
+		for a segfault when displaying some lines ending with
+		tabs; better handling of constant cursor position
+		display; improved color parsing in the rcfile; and
+		support for the "Regexp" toggle in tiny mode
+		(-R/--regexp is gone, and --restricted's short option
+		has been changed to -R), among other things.  Enjoy.
+
+2005.04.10 - GNU nano 1.3.7 claws its way to the top.  This release
+		mostly contains bugfixes for the massive amount of new
+		code in 1.3.6.  Among other things, nano builds with
+		debug support again; going into the help browser at the
+		"Read File" prompt no longer kicks you out of the prompt
+		after you exit the help browser; paragraph searching no
+		longer skips over certain cases of single-line
+		paragraphs; the titlebar no longer cuts off some UTF-8
+		strings prematurely; and the text displayed in the help
+		browser is now wrapped as it was in nano 1.2.x, taking
+		UTF-8 support into account.  New features include an
+		--enable/disable-utf8 configure option to explicitly
+		turn detection of UTF-8 support on or off, and sample
+		regexes for C++ as well as C.  Have fun.

 INSTRUCTIONS TO COMPILE AND INSTALL NANO CVS VERSIONS
------------------------------------------------------
+=====================================================
 
 GNU nano is available from CVS, but building this needs a bit more care
 than the official stable and unstable tarballs.
 
+
+Prerequisites
+-------------
+
 To successfully compile GNU nano from CVS, you'll need the following
 packages:
 
 - autoconf (version >= 2.54)
 - automake (version >= 1.7)
-- gettext (version >= 0.11.5)
-- groff
-- texinfo
+- gettext  (version >= 0.11.5)
+- groff    (version >= 1.12)
+- texinfo  (version >= 4.0)
 - cvs
 - ssh (with support for the SSH version 2 protocol)
-- glib 2.x (if your system doesn't have snprintf() and/or vsnprintf())
+- glib 2.x (if your system doesn't have vsnprintf(), which the configure
+  script will check for)
 - make, gcc and the normal development libraries (curses or slang, etc.)
 
 These should be available on your GNU mirror.  Note that you'll need a
 version of curses or slang with wide character support if you want nano
 to use UTF-8.
 
+
+Download the source
+-------------------
+
 First, you need to set up cvs to download the CVS tree using ssh.  If
 you're using a Bourne shell (e.g. bash or sh), do
-$ export CVS_RSH=ssh
+
+    $ export CVS_RSH=ssh
+
 If you're using a C shell (e.g. tcsh or csh), do
-$ setenv CVS_RSH ssh
 
-After it's set up, use the following command to download the CVS tree:
-$ cvs -z3 -d:ext:anoncvs@savannah.gnu.org:/cvsroot/nano checkout nano
+    $ setenv CVS_RSH ssh
 
-If you want to download the stable CVS branch, add "-r nano_1_0_branch":
-$ cvs -z3 -d:ext:anoncvs@savannah.gnu.org:/cvsroot/nano checkout -r nano_1_0_branch nano
+After that's set up, cd to your src directory and use the following
+command to download the CVS tree:
 
-Once you have the sources in the "nano" directory, cd into it, and
-execute the "autogen.sh" script in the top directory.  This will set up
-a configure script and Makefile.in, and you will be ready to compile
-with
-$ ./configure [--add-options-here] && make
+    $ cvs -z3 -d:pserver:anonymous@cvs.savannah.gnu.org:/sources/nano checkout nano
 
-Once it's done compiling,
-$ make install
-(as root) should put the required files in their respective directories.
+If you want to download the stable CVS branch, add "-r nano_1_2_branch":
+
+    $ cvs -z3 -d:pserver:anonymous@cvs.savannah.gnu.org:/sources/nano checkout -r nano_1_2_branch nano
+
+
+Generate the configure script
+-----------------------------
+
+Once you have the sources in the "nano" directory,
+
+    $ cd nano
+    $ ./autogen.sh
+
+This will set up a configure script and a Makefile.in file.
+
+
+Configure your build
+--------------------
+
+To configure your build, run the configure script from the nano source
+directory:
+
+    $ ./configure [--add-options-here]
+
+
+Build and install
+-----------------
+
+From the nano source directory, build the code with:
+
+    $ make
+
+Then, once it's done compiling, run
+
+    $ make install
+
+which should copy various files (i.e. the nano executable, the info and
+man pages, and syntax highlighting pattern files) to their appropriate
+directories.
+
+If you're installing into the default install directory (/usr/local),
+you'll need to run that "make install" command with root privileges.
+
+
+Problems?
+---------
 
 Please submit any bugs in the CVS branch to nano-devel@gnu.org.

+  - Blanking of the statusbar after 1 keystroke instead of 25 (-U).
+  - Word searches can optionally skip over punctuation (-W).
+  - Workaround for Delete's acting like Backspace (-d).
+  - Many more options are supported in the nanorc.
+  - Improvements to color syntax highlighting support: case insensitive
+    matching, the ability to include color syntaxes in separate files,
+    the ability to specify background colors without foreground colors,
+    etc.
+  - Insertion of single-byte characters via Esc Esc <000-255>.
+  - Insertion of all characters via "Verbatim Input" mode.
+  - Workaround for the "NumLock glitch".
+  - Meta-W now repeats the last search.  Wrapping is now toggled via
+    Meta-L.
+  - Replacing and spell checking only selected text.
+  - Indenting lines with one keystroke.
+  - Copying text into the cutbuffer without cutting it.
+  - Scrolling the text up and down single lines without moving the
+    cursor.
+  - PageUp and PageDown work more smoothly when using -S.
+  - Scrolling the help text up and down single lines.
+  - Cutting all text from the current position to the end of the file
+    with one keystroke.
+  - Justifying the entire file with one keystroke.
+  - Justifying without removing spaces from the ends of lines.
+  - Unjustifying after justifying and immediately resizing.
+  - Going to the first or last line of the current paragraph.
+  - Going to the first or last line of the file without having to go to
+    the "Search" prompt.
+  - Searching for filenames in the file browser.
+  - Displaying spaces and tabs differently to make it easier to tell
+    them apart.
+  - Many more functions available at the statusbar prompt: moving to the
+    next or previous word, searching for matching brackets, "Verbatim
+    Input" mode, etc.
+  - The glibc 2.2.3 crashes involving extended regular expressions are
+    no longer worked around, as they can break anything using extended
+    regular expressions, and glibc 2.2.3 is old.  You should upgrade to
+    at least glibc 2.2.4.
+
+* File Handling
+  - Automatic adding of newlines to the ends of files without them can
+    now be disabled (-L).
+  - Converting from and to DOS/Mac file format is now toggled only at
+    the "Write File" prompt, via Meta-D and Meta-M, and the default file
+    format to save in is now set depending on what format the file was
+    originally in.  -D now makes nano use bold text instead of reverse
+    video text, and Meta-D at the edit window now does a
+    word/line/character count.  -O now makes the unused second line of
+    the screen part of the edit window, and Meta-O at the edit window
+    now toggles this behavior.
+  - Converting files that contain a mix of DOS and Mac format lines.
+  - Automatic switching on of -N with binary files has been removed, as
+    it causes problems with UTF-8 support.

   <p>The <a href="http://www.debian.org/">Debian GNU/Linux</a> distribution, known for its strict standards in distributing truly &quot;free&quot; software (i.e. software with no restrictions on redistribution), would not include a binary package for Pine or Pico. Many people had a serious dilemma: they loved these programs, but they were not truly free software in the <a href="http://www.gnu.org/philosophy/free-sw.html">GNU</a> sense of the word.</p>
   <p><b>The event...</b></p>
   <p>It was in late 1999 when Chris Allegretta (our hero) was yet again complaining to himself about the less-than-perfect license Pico was distributed under, the 1000 makefiles that came with it and how just a few small improvements could make it the Best Editor in the World (TM). Having been a convert from Slackware to Debian, he missed having a simple binary package that included Pine and Pico, and had grown tired of downloading them himself.</p>
-  <p>Finally something snapped inside and Chris coded and hacked like a madman for many hours straight one weekend to make a (barely usable) Pico clone, at the time called TIP (Tip Isn't Pico). The program could not be invoked without a filename, could not save files, had no help menu, spell checker, and so forth. But over time it improved, and with the help of a few great coders it matured to the (hopefully) stable state it is today.</p>

   <p>In February 2001, nano was declared an official GNU program by Richard Stallman. Nano also reached its first production release on March 22, 2001.</p></blockquote>
 <h2><a name="1.5"></a>1.5. Why the name change from TIP?</h2>
 <blockquote><p>On January 10, 2000, TIP was officially renamed to nano because of a namespace conflict with another program called 'tip'. The original 'tip' program &quot;establishes a full duplex terminal connection to a remote host&quot;, and was included with many older Unix systems (and newer ones like Solaris). The conflict was not noticed at first because there is no 'tip' utility included with most GNU/Linux distributions (where nano was developed).</p></blockquote>

Then when you want to enable inserting a file into its own buffer instead of into the current file, just hit <b>Meta-F</b>, then insert the file as normal with <b>^R</b>.

 <h2><a name="3.9"></a>3.9. How do I make a .nanorc file that nano will read when I start it?</h2>
 <blockquote><p>It's not hard at all! But, your version of nano must have been compiled with <b>--enable-nanorc</b>, and again must be version 1.1.12 or newer (use nano -V to check your version and compiled features). Then simply copy the <b>nanorc.sample</b> that came with the nano source or your nano package (most likely in /usr/doc/nano) to .nanorc in your home directory. If you didn't get one, the syntax is simple. Flags are turned on and off by using the word <b>set</b> and the getopt_long flag for the feature, for example &quot;set nowrap&quot; or &quot;set suspend&quot;.</p></blockquote>

+This manual page briefly documents GNU \fBnano\fP's rcfile.
 .PP
 \fBnano\fP is a small, free and friendly editor which aims to replace
 Pico, the default editor included in the non-free Pine package.  Rather
 than just copying Pico's look and feel, \fBnano\fP also implements some
 missing (or disabled by default) features in Pico, such as "search and
-replace" and "go to line number".

 .PP
-The \fInanorc\fP file contains the default settings for \fBnano\fP.
-During startup, \fBnano\fP will first read its system-wide settings from
-.IR SYSCONFDIR/nanorc ,
-and then user-specific settings from
-.IR ~/.nanorc .
+The \fInanorc\fP file contains the default settings for \fBnano\fP.  It

+first read its system-wide settings from \fISYSCONFDIR/nanorc\fP, and
+then user-specific settings from \fI~/.nanorc\fP.
 
 .SH OPTIONS
-The configuration file accepts a series of "set" and "unset" commands,
-which can be used to configure nano on startup without using the
-command-line options.  Additionally, the "syntax" and "color" keywords
-are used to define syntax highlighting rules for different text
-patterns.  GNU nano will read one command per line.

+## color foreground,background "regex" ["regex"...]
+## or

+##
+## Valid colors: white, black, red, blue, green, yellow, magenta, cyan.
+## For foreground colors, you may use the prefix "bright" to get a
+## stronger highlight.
+##
+## To use multi-line regexes, use the start="regex" end="regex"
+## [start="regex" end="regex"...] format.
+##
+## If your system supports transparency, not specifying a background
+## color will use a transparent color.  If you don't want this, be sure
+## to set the background color to black or white.
+##
+## If you wish, you may put your syntaxes in separate files.  You can
+## make use of such files (which can only include "syntax", "color", and
+## "icolor" commands) as follows:
+##
+## include "/path/to/syntax_file.nanorc"
+##
+## Unless otherwise noted, the name of the syntax file (without the
+## ".nanorc" extension) should be the same as the "short description"
+## name inside that file.  These names are kept fairly short to make
+## them easier to remember and faster to type using nano's -Y option.
+##
+## All regexes should be extended regular expressions.

+@chapter Nanorc Files
+
+The nanorc files contain the default settings for @code{nano}.  They
+should not be in DOS or Mac format.  During startup, @code{nano} will
+first read its system-wide settings from SYSCONFDIR/nanorc, and then
+user-specific settings from ~/.nanorc.
+
+A nanorc file accepts a series of "set" and "unset" commands, which can
+be used to configure @code{nano} on startup without using the command
+line options.  Additionally, the "syntax", "color", and "icolor"
+keywords are used to define syntax highlighting rules for different text
+patterns.  @code{nano} will read one command per line.
+
+Options in nanorc files take precedence over @code{nano}'s defaults, and
+command line options override nanorc settings.  Options are also unset
+by default, except for those that take arguments.
+
+Quotes inside string parameters don't have to be escaped with
+backslashes.  The last double quote in the string will be treated as its
+end.  For example, for the "brackets" option,
+
+@quotation
+@code{""')>]@}"}
+@end quotation
+
+will match @code{"}, @code{'}, @code{)}, @code{>}, @code{]}, and
+@code{@}}.
+
+The supported commands and arguments are:
+
+@table @code
+
+@item set/unset autoindent
+Use auto-indentation.
+
+@item set/unset backup
+Create backup files in "filename~".
+
+@item set backupdir "directory"
+Set the directory where @code{nano} puts unique backup files if file
+backups are enabled.
+
+@item set/unset backwards
+Do backwards searches by default.
+
+@item set/unset boldtext
+Use bold text instead of reverse video text.
+
+@item set brackets "string"
+Set the characters treated as closing brackets when justifying
+paragraphs.  They cannot contain blank characters.  Only closing
+punctuation, optionally followed by closing brackets, can end sentences.
+The default value is
+
+@quotation
+@code{""')>]@}"}
+@end quotation
+
+@item set/unset casesensitive
+Do case sensitive searches by default.
+
+@item set/unset const
+Constantly display the cursor position in the status bar.
+
+@item set/unset cut
+Use cut to end of line by default, instead of cutting the whole line.
+
+@item set fill "n"
+Wrap lines at column number "n".  If "n" is 0 or less, the maximum line
+length will be the screen width less "n" columns.  The default value is
+-8.
+
+@item set/unset historylog
+Enable ~/.nano_history for saving and reading search/replace strings.
+
+@item set matchbrackets "string"
+Set the opening and closing brackets that can be found by bracket
+searches.  They cannot contain blank characters.  The former set must
+come before the latter set, and both must be in the same order.  The
+default value is
+
+@quotation
+@code{"(<[@{)>]@}"}
+@end quotation
+
+@item set/unset morespace
+Use the blank line below the titlebar as extra editing space.
+
+@item set/unset mouse
+Enable mouse support, so that mouse clicks can be used to place the
+cursor, set the mark (with a double click), or execute shortcuts.
+
+@item set/unset multibuffer
+Allow inserting files into their own buffers.
+
+@item set/unset noconvert
+Don't convert files from DOS/Mac format.
+
+@item set/unset nofollow
+Don't follow symlinks when writing files.
+
+@item set/unset nohelp
+Don't display the help lists at the bottom of the screen.
+
+@item set/unset nonewlines
+Don't add newlines to the ends of files.
+
+@item set/unset nowrap
+Don't wrap text at all.
+
+@item set operatingdir "directory"
+@code{nano} will only read and write files inside "directory" and its
+subdirectories.  Also, the current directory is changed to here, so
+files are inserted from this directory.  By default, the operating
+directory feature is turned off.
+
+@item set/unset preserve
+Preserve the XON and XOFF keys (^Q and ^S).
+
+@item set punct "string"
+Set the characters treated as closing punctuation when justifying
+paragraphs.  They cannot contain blank characters.  Only closing
+punctuation, optionally followed by closing brackets, can end sentences.
+The default value is @code{"!.?"}.
+
+@item set/unset quickblank
+Do quick statusbar blanking.  Statusbar messages will disappear after 1
+keystroke instead of 25.
+
+@item set quotestr "string"
+The email-quote string, used to justify email-quoted paragraphs.  This
+is an extended regular expression if your system supports them,
+otherwise a literal string.  The default value is
+
+@quotation
+@code{"^([ \\t]*[#:>\\|@}])+"}
+@end quotation
+
+if you have extended regular expression support, or "> " otherwise.
+Note that '\\t' stands for a literal Tab character.
+
+@item set/unset rebinddelete
+Interpret the Delete key differently so that both Backspace and Delete
+work properly.  You should only need to use this option if Backspace
+acts like Delete on your system.
+
+@item set/unset rebindkeypad
+Interpret the numeric keypad keys so that they all work properly.  You
+should only need to use this option if they don't, as mouse support
+won't work properly with this option enabled.
+
+@item set/unset regexp
+Do extended regular expression searches by default.
+
+@item set/unset smarthome
+Make the Home key smarter.  When Home is pressed anywhere but at the
+very beginning of non-whitespace characters on a line, the cursor will
+jump to that beginning (either forwards or backwards).  If the cursor is
+already at that position, it will jump to the true beginning of the
+line.
+
+@item set/unset smooth
+Use smooth scrolling by default.
+
+@item set speller "spellprog"
+Use spelling checker "spellprog" instead of the built-in one, which
+calls "spell".
+
+@item set/unset suspend
+Allow @code{nano} to be suspended.
+
+@item set tabsize "n"
+Use a tab size of "n" columns.  The value of "n" must be greater than 0.
+The default value is 8.
+
+@item set/unset tabstospaces
+Convert typed tabs to spaces.
+
+@item set/unset tempfile
+Save automatically on exit, don't prompt.
+
+@item set/unset view
+Disallow file modification.
+
+@item set whitespace "string"
+Set the two characters used to display the first characters of tabs and
+spaces.  They must be single-column characters.
+
+@item set/unset wordbounds
+Detect word boundaries more accurately by treating punctuation
+characters as part of a word.
+
+@item syntax "str" ["fileregex" @dots{} ]
+Defines a syntax named "str" which can be activated via the -Y/--syntax
+command line option, or will be automatically activated if the current
+filename matches the extended regular expression "fileregex".  All
+following "color" and "icolor" statements will apply to "syntax" until a
+new syntax is defined.
+
+The "none" syntax is reserved; specifying it on the command line is the
+same as not having a syntax at all.  The "default" syntax is special: it
+takes no "fileregex", and applies to files that don't match any other
+syntax's "fileregex".
+
+@item color fgcolor,bgcolor "regex" @dots{}
+For the currently defined syntax, display all expressions matching the
+extended regular expression "regex" with foreground color "fgcolor" and
+background color "bgcolor", at least one of which must be specified.
+Legal colors for foreground and background color are: white, black, red,
+blue, green, yellow, magenta, and cyan.  You may use the prefix "bright"
+to force a stronger color highlight for the foreground.  If your
+terminal supports transparency, not specifying a "bgcolor" tells "nano"
+to attempt to use a transparent background.
+
+@item icolor fgcolor,bgcolor "regex" @dots{}
+Same as above, except that the expression matching is case insensitive.
+
+@item color fgcolor,bgcolor start="sr" end="er"
+Display expressions which start with the extended regular expression
+"sr" and end with the extended regular expression "er" with foreground
+color "fgcolor" and background color "bgcolor", at least one of which
+must be specified.  This allows syntax highlighting to span multiple
+lines.  Note that all subsequent instances of "sr" after an initial "sr"
+is found will be highlighted until the first instance of "er".
+
+@item icolor fgcolor,bgcolor start="sr" end="er"
+Same as above, except that the expression matching is case insensitive.
+
+@item include "syntaxfile"
+Read in self-contained color syntaxes from "syntaxfile".  Note that
+"syntaxfile" can only contain "syntax", "color", and "icolor" commands.
