REFRESING OUR EMACS CONCEPTS:
perlnow.el is a collection of utility commands for perl programmers who use emacs. These commands are designed to help automate some routine tasks in the initial creation of perl scripts and modules. Commands are also provided to assist in running, testing and debugging inside of emacs.
Tk is a GUI toolkit developed by John Ousterhout, initially as a Tcl
extension, to facilitate the creation of graphical user interfaces.
Since then, it has grown in popularity, and as a result has been ported
to many different languages. Nick Ing-Simmons ported Tk to Perl, giving
us Perl/Tk.
