At the moment, no.  This is mostly out of laziness, but partially
because I came to think that swcron was sort of pointless, more or
less immediately after writing it.  You need to start a separate
process to run the crons anyway, and swpython can now be used, thanks
to you, Drew, in the shebangs of scripts -- so swcron doesn't give you
that much extra, except the ability to configure jobs in the midst of
your skunkweb configuration.  Also it is possible for a service to add
a cron job -- but I'm not sure whether you'd want to do that anyway.

That doesn't mean it is useless or shouldn't be documented.  The
cronjob pylib actually has better docstrings than I usually am
responsible for.  Brian O. and I started doing a bit of work on the
manual last week and I'll try to set aside time every week until we
have something up-to-date and adequate, if not comprehensive.

For the record, CronJobs should be a list of cronjob.CronJobs.  A
CronJob is a wrapper around a callable thing that includes timing
information.  You probably want to produce one with the "from_spec"
class method; see the docstrings for details.  CronLogger handles the
output and error streams of running the job; the one configured by
default (defined in the cron service) sends email, and you can stick
to- and fro- addresses in it.

That's all there is to know.
