 If a list is passed in, the returned list of files is constrained to those
 found under the paths passed in. i.e. calling find(["LayoutTests/fast"])
 will only return files under that directory.
 
 If a set of skipped directories is passed in, the function will filter out
 the files lying in these directories i.e. find(["LayoutTests"], set(["fast"]))
 will return everything except files in fast subfolder.
 
 If a callback is passed in, it will be called for the each file and the file
 will be included into the result if the callback returns True.
-The callback has to take three arguments: filesystem, dirname and filename."""
