If you can live without a menu interface you can do it all with pbmplus

cat foo.gif | giftoppm | ppmtopbm | pbmtoascii > foo.ascii

pbmplus comes with the X11R4 distribution (among other places).
Output from pbmtoascii is described in the man page as "a somewhat crude ASCII
graphic" - I've no idea what the tools Jeff describes are like.
pbmplus also has assorted tools (e.g. scale, contrast normalisation, edge
enhancement, smoothing) that might or might not help at some point in the pipe.

"My own opinions" - and I haven't tried GIF with pbm. Works for Sun raster or
xwd to ASCII though.
