I played with the bash syntax for a little bit, and  I came up with the 
following one-liner that should print out all the executable files a package 
installed on your system.  The basic syntax is:

$ PACKAGE=speedcrunch
$ dpkg -L "$PACKAGE" | xargs -n 1 | { while read FNAME; do if [ ! -d 
"$FNAME" ]; then if [ -x "$FNAME" ]; then echo "$FNAME"; fi; fi; done; }

If you save that in a script in your path somewhere, it could be useful for 
finding executable names.
