Description
  
   pgtclsh is a Tcl
   shell interface extended with
   PostgreSQL database access functions.
   (Essentially, it is tclsh with
   libpgtcl loaded.)  Like with the regular
   Tcl shell, the first command line
   argument is a script file, any remaining arguments are passed to
   the script.  If no script file is named, the shell is
   interactive.
  
   A Tcl shell with
   Tk and
   PostgreSQL functions is available as pgtksh.
