NAME
       boxes - text mode box and comment drawing filter

SYNOPSIS
       boxes  [-hlmrv] [-a format] [-d design] [-f file] [-i indent] [-k bool]
       [-p pad]	[-s size] [-t tabopts] [infile [outfile]]

DESCRIPTION
       Boxes is	a text filter which can	draw any kind of box around its	 input
       text.  Box design choices range from simple boxes to complex ASCII art.
       A box can also be removed and repaired, even if it has been badly  dam-
       aged  by	 editing  of  the  text	inside.	Since boxes may	be open	on any
       side, boxes can also be used to create regional comments	 in  any  pro-
       gramming	 language.   New  box designs of all sorts can easily be added
       and shared by appending to a free format	configuration file.
       boxes was originally intended to	be used	with the vim(1)	 text  editor,
       but  it	can be tied to any text	editor which supports filters, as well
       as called from the command line as a standalone tool.

OPTIONS
       Options offered by boxes	are the	following:

       -a string
	     Alignment/positioning of text inside box.	This  option  takes  a
	     format string argument which is read from left to right. The for-
	     mat string	may not	contain	whitespace and must consist of one  or
	     more of the following components:

	     hx	- horizontal alignment of the input text block inside a	poten-
	     tially larger box.	Possible values	for x are  l  (ell,  for  left
	     alignment),  c  (center),	or r (right). This does	not affect the
	     justification of text lines within	the input text block (use  the
	     j argument	instead).
	     vx	 -  vertical alignment of the input text block inside a	poten-
	     tially larger box.	Possible values	for x are t  (for  top	align-
	     ment), c (center),	or b (bottom).
	     jx	- justification	of lines within	the input text block. Possible
	     values for	x are l	(ell, for left justification), c (center),  or
	     r	(right).  This does not	affect the alignment of	the input text
	     block itself within the box. Use the h and	v arguments for	 input
	     text block	positioning.

	     Short hand	notations (can be combined with	the above arguments):
	     l (ell) - short for hlvcjl
	     c - short for hcvcjc
	     r - short for hrvcjr

	     The factory default setting for -a	is hlvt.

       -c string
	     Command  line design definition for simple	cases. The argument of
	     this option is the	definition for the "west" (W) shape.  The  de-
	     fined  shape must consist of exactly one line, i.e. no multi-line
	     shapes are	allowed. The -c	option is intended as a	 shortcut  for
	     those  cases  where  simple  regional comments are	to be created,
	     which only	need a certain character or sequence of	characters  to
	     be	 placed	in front of every line.	In such	cases, it is much more
	     convenient	to simply specify -c than to do	a complete design def-
	     inition in	one's config file, where the only shape	defined	is the
	     west shape.
	     This option implies a -d and does not access the config file.  -c
	     may  of  course  be used in conjunction with any of the other op-
	     tions. By default,	-c is not specified.

       -d string
	     Design selection. The one argument	of this	option is the name  of
	     the design	to use.

       -f string
	     Use alternate config file.	The one	argument of this option	is the
	     name of a valid boxes config file,	containing  new	 and  exciting
	     designs!

       -h    Print usage information.

       -i string
	     Indentation  mode.	Possible arguments are "text" (indent text in-
	     side of box), "box" (indent box, not  text	 inside	 of  box),  or
	     "none"  (throw  away  indentation). Arguments may be abbreviated.
	     The default is to indent the box, but not the text.

       -k bool
	     Kill leading/trailing blank lines on removal. The value  of  bool
	     can  be  specified	as on, yes, true, 1, or	t, all meaning yes, or
	     off, no, false, 0,	or f, which mean no. This is case-insensitive.
	     This  option  only	takes effect in	connection with	-r.  If	set to
	     yes, leading and trailing blank lines will	be  removed  from  the
	     output. If	set to no, the entire content of the former box	is re-
	     turned.  The default is no, if both the top and the  bottom  part
	     of	 the box are open, as is the case with most regional comments.
	     If	the box's design defines a top part or a bottom	part, the  de-
	     fault is yes.

       -l    (ell)  List  designs. Produces a listing of all available box de-
	     signs in the config file, along with a sample box and information
	     about  it's  creator.   Also  checks  syntax of the entire	config
	     file. If used in connection with -d, displays  detailed  informa-
	     tion about	the specified design.

       -m    Mend box. This removes a (potentially broken) box as with -r, and
	     redraws it	afterwards. The	mended box is drawn according  to  the
	     options  given.  This  may	 be important to know when it comes to
	     restoring padding,	identation, etc. for the mended	 box.  Implies
	     -k	false.

       -p string
	     Padding.  Specify	padding	 in spaces around the input text block
	     for all sides of the box. The argument  string  may  not  contain
	     whitespace	 and  must  consist  of	a combination of the following
	     characters, each followed by a number indicating the  padding  in
	     spaces:
	     a - (all) give padding for	all sides at once
	     h - (horiz) give padding for both horizontal sides
	     v - (vertical) give padding for both vertical sides
	     b - (bottom) give padding for bottom (south) side
	     l - (left)	give padding for left (west) side
	     t - (top) give padding for	top (north) side
	     r - (right) give padding for right	(east) side
	     Example:  -p  a4t2	would define the padding to be 4 characters on
	     all sides,	except for the top of the box, where  the  input  text
	     block will	be only	2 lines	away from the box.
	     By	 default,  unless  specified  otherwise	in the config file, no
	     padding is	used.

       -r    Remove box. Removes an existing box instead of drawing it.	 Which
	     design to use is detected automatically. In order to save time or
	     in	case the detection does	not decide correctly, combine with  -d
	     to	specify	the design. The	default	is to draw a new box.

       -s widthxheight
	     Box  size.	This option specifies the desired box size in units of
	     columns (for width) and lines (for	height).   If  only  a	single
	     number  is	 given	as argument, this number specifies the desired
	     box width.	A single number	prefixed by 'x'	specifies only the box
	     height.   The actual resulting box	size may vary depending	on the
	     individual	shape sizes of the chosen design. Also,	other  command
	     line options may influence	the box	size (such as -p).
	     By	default, the smallest possible box is created around the text.

       -t string
	     Tab  handling. This option	controls how tab characters in the in-
	     put text are handled. The option string must always begin with  a
	     uint  number indicating the distance between tab stops. It	is im-
	     portant that this value be	set correctly, or tabulator characters
	     will  upset  your input text.  The	correct	tab distance value de-
	     pends on the settings used	for the	text  you  are	processing.  A
	     common value is 8.
	     Immediately following the tab distance, an	optional character can
	     be	appended, telling boxes	how to treat  the  leading  tabs.  The
	     following options are available:
	     e - expand	tabs into spaces
	     k - keep tabs as close to what they were as possible
	     u - unexpand tabs.	This makes boxes turn as many spaces as	possi-
	     ble into tabs.

	     In	order to maintain backwards compatibility, the -t  string  can
	     be	 just  a  number. In that case,	e is assumed for tab handling,
	     which removes all tabs and	replaces them with spaces. The factory
	     default for the -t	option is simply 8, which is just such a case.
	     For  example, you could specify -t	4u in order to have your lead-
	     ing tabs unexpanded. In the box content,  tabs  are  always  con-
	     verted into spaces. The tab distance in this example is 4.

       -v    Print out current version number.

CONFIGURATION FILES
       Boxes  will  use	 the  configuration file specified on the command line
       (using -f).  If no config file is specified on the command line,	 boxes
       will  check  for	 the  BOXES  environment variable, which may contain a
       filename	to  use.  If  BOXES  is	 not  set,  boxes  will	 try  to  read
       $HOME/.boxes  and use it	as a config file. Failing that,	boxes will try
       to read the system-wide config file (see	FILES).

       The syntax of boxes config files	is described on	the website  (see  be-
       low). They are quite self-explanatory, though.
