+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 keyboard 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.

 <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.

 <blockquote><p>It was decided that consistency was nice, but people are used to Pico's inconsistent behavior.  Also, in version 1.1.99pre1, search and replace history was introduced.  If you wish to edit your previous search/replace entry (or any previous entry), you can do so by hitting the up arrow to cycle through your history.  This method allows the best of both worlds: You don't need to erase the previous string if you want to enter a new one, but you can with one keystroke recall previous entries for editing. Therefore there is now no "Pico mode", nano is and has always been a Pico <b>clone</b>, and clones by default should be compatible.</p></blockquote>

+
+.SH DESCRIPTION
+This manual page documents briefly the \fBrnano\fP command.
+.PP
+.\" TeX users may be more comfortable with the \fB<whatever>\fP and
+.\" \fI<whatever>\fP escape sequences to invoke bold face and italics, 
+.\" respectively.
+\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
+\fBrnano\fP is a restricted version of \fBnano\fP, which only edits
+specific files and doesn't allow the user access to the filesystem or a
+command shell.
+.PP
+In restricted mode, \fBnano\fP will \fInot\fP:
+.IP \[bu] 2
+read or write to any file not specified on the command line;
+.IP \[bu]
+read any nanorc files;
+.IP \[bu]
+allow suspending;
+.IP \[bu]
+allow a file to be appended to, prepended to, or saved under a different
+name;
+.IP \[bu]
+use backup files or spell checking.
+
