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

Syntax
  pico [ options ] [ file ]

Description
  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
  contains 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
  substitute 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.

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

  -a   Display all files including those beginning with a period (.).

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

  -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
       conjunction 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
       positioned 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
       position 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
       accessible.  Likewise, the file browser is limited to the specified
       directory 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"
       command.

  -v   View the file only, disallowing any editing.

  -version
       Print Pico version and exit.

  -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".

Bugs
  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.

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