# Without 'filename', looks for MANIFEST in the current dir.
# With '-o outfile', writes the sorted MANIFEST to the specified file.
# Prints the result of the sort to stderr. '-q' silences this.
# The exit code for the script is the sort result status
# (i.e., 0 means already sorted properly, 1 means not properly sorted)
