one could kludge this by setting the compression parameters desired on the tree
then using a perl script to walk the tree, copying each file to a tmp file,
renaming the original to an arbitrary name, renaming the tmp to the name of the
original, then updating the new file with the original file's metadata, do a
checksum sanity check, then delete the uncompressed original.
