"""
Generate IRR route and route6 objects from ROAs.
The only required argument is the name of a directory tree containing
the validated outpt of an rcynic run. If you follow the default
naming scheme this will be /some/where/rcynic-data/authenticated.
If given the --output option, the argument to that option will be
interpreted as the name of a directory (which will be created if it
does not already exist) in which to write route and route6 objects,
one object per file.
If not given the --output option, this program will write all the
route and route6 objects to standard output, separated by blank lines.
In this mode, if also given the --email option, the program will
generate a fake RFC (2)822 header suitable for piping all of this into
irr_rpsl_submit.
The other options allow control of several required fields, to let you
change email addresses and so forth if the defaults values aren't
right.
