Maybe a pointless question, but I can't find any documentation on my
system or online that describes wrudf. It's part of the udftools
package. It launches a sort of shell and seems to allow one to look into
unmounted UDF volumes -- lsc/cdc list and change directories on a CD,
while lsh/cdh do the same operations on your hard drive. Does it do
anything else? It looks like it could be some sort of data rescue
program, but I can't get it to do anything other than ls/cd.
