"""This script generates a manifest file for nacl_io's HTTP file-system.
Files and directory paths are specified on the command-line. The names
with glob and directories are recursed to form a list of files.
For each file, the mode bits, size and path relative to the CWD are written
to the output file which is stdout by default.
