Bug#921607: discard mupdf shell script

[Mike]

There is no help/?-option in the launcher script.

There are too few options also.
The 'exec 3<"$tmp"' is useless.

And who has a pdf.gz file?


The whole script should be discarded. A simple "ln -s 
/usr/lib/mupdf/mupdf-x11 /usr/bin/mupdf" will do it!
