Grail is an extensible Internet browser written entirely in the interpreted object-oriented programming language Python. It runs on UNIX, and, to some extent, on Windows and Macintosh.
Grail is easily extended to support new protocols or file formats. Grail is distributed in source form, free of charge, and without warranties. It requires recent versions of Python and Tcl/Tk to run.
