Short: Use ReqTools filerequester with Emacs!
Type: util/gnu
Uploader: bitti@cs.tut.fi

I've always wanted GnuEmacs to ask for files with a decent graphical
filerequester. I mean, there are menus but what good is selecting
'Open' from menu if you have to type in the filename using keyboard
anyway!

Filereq is an Emacs elisp file (two if you count the byte-compiled
version, four if you count the menu files) and an arexx script that
enables you to use ReqTools filerequester in Emacs.
