Copies files from nested folders into one source, flat directory.

This python class converts a permission mask in symbolic format (the kind a diretcory listing produces, ex.: drwxr-xr-x) to a string that's usable in a chmod command.

ex.: chmod u=rwx,g=rwx,o=rwtx ~/myscripts/convert_mask.py

This can be very useful when recovering permissions from a backup.
