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.
