screen: Dump Termcap

 
 16.2 Write out the window's termcap entry
 =========================================
 
  -- Command: dumptermcap
      ('C-a .')
      Write the termcap entry for the virtual terminal optimized for the
      currently active window to the file '.termcap' in the user's
      '$HOME/.screen' directory (or wherever 'screen' stores its sockets.
      SeeFiles).  This termcap entry is identical to the value of
      the environment variable '$TERMCAP' that is set up by 'screen' for
      each window.  For terminfo based systems you will need to run a
      converter like 'captoinfo' and then compile the entry with 'tic'.
