    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 immedi-
         ately 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 char-
         acter, e.g. "ESC ESC c" would be equivalent  to  entering  a
         ctrl-c.   The editor has five basic features: paragraph jus-
         tification, 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.   Para-
         graphs  are  delimited by blank lines, or by lines beginning
         with a space or tab.  Unjustification can  be  done  immedi-
         ately  after  justification using the control-U key combina-
         tion.
    
         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  can-
         celled  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  selec-
         tion.  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  dele-
         tion.
    
         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)
    
         -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  cur-
              sor  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.
    
         -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 '$'  char-
         acter  at the end of the line.  Long lines are scrolled hor-
         izontally as the cursor moves through them.
