Description
  
   pgtksh is a Tcl/Tk
   shell interface extended with PostgreSQL
   database access functions.  (Essentially, it is
   wish with libpgtcl loaded.)
   Like with wish, the regular
   Tcl/Tk shell, the first command line
   argument is a script file, any remaining arguments are passed to
   the script.  Special options may be processed by the
   X Window System libraries instead.
   If no script file is named, the shell is interactive.
  
   A plain Tcl shell with
   PostgreSQL functions is available as pgtclsh.
