[plug] rm of contents

[Craig Dyke]

Hi All

To some of you this will appear trivial, but, I can't seem to work it out.

I have a directory structure that looks like:

dir -->  file
            file2
            dir2 -->    file
                            file2
                            file3
            file3

Now my aim is to delete all the files in each directory but leave
directories intact.
Would like it to work irrelevant of how deep the structure is.
