  pico - simple	text editor in the style of the	Pine Composer

  pico [ options ] [ file ]

  Pico is a simple, display-oriented text editor based on the Pine message
  system composer.  As with Pine, commands are displayed at the	bottom of the
  screen, and context-sensitive	help is	provided.  As characters are typed
  they are immediately inserted	into the text.

  Editing commands are entered using control-key combinations.	As a work-
  around for communications programs that swallow certain control characters,
  you can emulate a control key	by pressing ESCAPE twice, followed by the
  desired control character, e.g. "ESC ESC c" would be equivalent to entering
  a ctrl-c.  The editor	has five basic features: paragraph justification,
  searching, block cut/paste, a	spelling checker, and a	file browser.

  Paragraph justification (or filling) takes place in the paragraph that con-
  tains	the cursor, or,	if the cursor is between lines,	in the paragraph
  immediately below.  Paragraphs are delimited by blank	lines, or by lines
  beginning with a space or tab.  Unjustification can be done immediately
  after	justification using the	control-U key combination.

  String searches are not sensitive to case.  A	search begins at the current
  cursor position and wraps around the end of the text.	 The most recent
  search string	is offered as the default in subsequent	searches.

  Blocks of text can be	moved, copied or deleted with creative use of the
  command for mark (ctrl-^), delete (ctrl-k) and undelete (ctrl-u).  The
  delete command will remove text between the "mark" and the current cursor
  position, and	place it in the	"cut" buffer.  The undelete command effects a
  "paste" at the current cursor	position.

  The spell checker examines all words in the text.  It	then offers, in	turn,
  each misspelled word for correction while highlighting it in the text.
  Spell	checking can be	cancelled at any time. Alternatively, pico will	sub-
  stitute for the default spell	checking routine a routine defined by the
  SPELL	environment variable.  The replacement routine should read standard
  input	and write standard output.

  The file browser is offered as an option in the "Read	File" and "Write Out"
  command prompts.  It is intended to help in searching	for specific files
  and navigating directory hierarchies.	 Filenames with	sizes and names	of
  directories in the current working directory are presented for selection.
  The current working directory	is displayed on	the top	line of	the display
  while	the list of available commands takes up	the bottom two.	 Several
  basic	file manipulation functions are	supported:  file renaming, copying,
  and deletion.

  More specific	help is	available in pico's online help.


  +n   Causes pico to be started with the cursor located n lines into the
       file. (Note: no space between "+" sign and number)

  -b   Enable the option to Replace text matches found using the "Where	is"

  -d   Rebind the "delete" key so the character	the cursor is on is rubbed
       out rather than the character to	its left.

  -e   Enable file name	completion.

  -f   Use function keys for commands.	This option supported only in con-
       junction	with UW	Enhanced NCSA telnet.

  -h   List valid command line options.

  -j   Enable "Goto" command in	the file browser.  This	enables	the command
       to permit explicitly telling pilot which	directory to visit.

  -g   Enable "Show Cursor" mode in file browser.  Cause cursor	to be posi-
       tioned before the current selection rather than placed at the lower
       left of the display.

  -k   Causes "Cut Text" command to remove characters from the cursor posi-
       tion to the end of the line rather than remove the entire line.

  -m   Enable mouse functionality.  This only works when pico is run from
       within an X Window System "xterm" window.

  -nn  The -nn option enables new mail notification.  The n argument is
       optional, and specifies how often, in seconds, your mailbox is checked
       for new mail.  For example, -n60	causes pico to check for new mail
       once every minute.  The default interval	is 180 seconds,	while the
       minimum allowed is 30. (Note: no	space between "n" and the number)

  -o dir
       Sets operating directory.  Only files within this directory are acces-
       sible.  Likewise, the file browser is limited to	the specified direc-
       tory subtree.

  -rn  Sets column used	to limit the "Justify" command's right margin

  -s speller
       Specify an alternate program spell to use when spell checking.

  -t   Enable "tool" mode.  Intended for when pico is used as the editor
       within other tools (e.g., Elm, Pnews).  Pico will not prompt for	save
       on exit,	and will not rename the	buffer during the "Write Out" com-

  -v   View the	file only, disallowing any editing.

  -w   Disable word wrap (thus allow editing of	long lines).

  -x   Disable keymenu at the bottom of	the screen.

  -z   Enable ^Z suspension of pico.

  -q   Termcap or terminfo definition for input	escape sequences are used in
       preference to sequences defined by default.  This option	is only
       available if pico was compiled with the TERMCAP_WINS define turned on.

  Lastly, when a running pico is disconnected (i.e., receives a	SIGHUP), pico
  will save the	current	work if	needed before exiting.	Work is	saved under
  the current filename with ".save" appended.  If the current work is
  unnamed, it is saved under the filename "pico.save".

  The manner in	which lines longer than	the display width are dealt is not
  immediately obvious.	Lines that continue beyond the edge of the display
  are indicated	by a '$' character at the end of the line.  Long lines are
  scrolled horizontally	as the cursor moves through them.

  pico.save	   Unnamed interrupted work saved here.
  *.save	   Interrupted work on a named file is saved here.
