"""
Script to reprocess ZDAB files from SNO and write out orphans. Copied mostly
from zdab-reprocess, but I changed the command file template. To reprocess a
single file:

    $ ./zdab-reprocess-orphans FILENAME

and to batch reprocess:

    $ ./zdab-reprocessi-orphans FILENAME FILENAME ...

By default, the reprocessed files will be stored in the current working
directory with _reprocessed appended to the name, but this can be changed by
passing a different suffix on the command line. For example:

    $ ./zdab-reprocess-orphans --suffix [suffix] SNOCR_00000100004_000_p2.xzdab

will produce a file named SNOCR_00000100004_000_p2_suffix.xzdab.
