If your directory and/or file names have spaces, you will have to quote
the filenames somehow: 'file name' vs. file_name. Maybe you could escape
the spaces? None of my names have spaces, for exactly this reason.

There is no cp -R. What this is doing is replicating the directory
structure, then copying each file. I missed it too, the first several
times I looked at it. Almost the entire script is the definition of the
traverse() function, which is called in the last line. The function then
calls itself whenever it finds a directory, which makes it recurse. I
thought it was pretty clever; wish I'd thought of it.

So was I; that's the main reason why there are all those `echo
"something"` lines - I wanted to see what it would try to do, before
actually turning it loose on my files. That and the fact that doing all
the conversions takes a few hours.
