With this check-in, syck is more-or-less in the same state
as when syck was dropped immediately after rpm5.org
was started.

The main difference now is that syck is a toplevel cvs module rather
than a cancerous snarl within rpm cvs. That's good.

I will continue integrating with the usual internal/external AutoFu  
as devel
progresses. What I needed atm was a reference library that isn't  
going to change
randomly for reasons that I have no control over.

The visible proof-of-concept deliverable will be a parser
for externally configured triggers in /etc/rpm/sysinfo/Triggername
as described in another message.

The other usage case will be either a C/lua well-formedness test
for rpm --yaml within rpm "make check". I still am mistrustful
that all the esaping and indenting in the :yaml format extension
is relaible because of the lack of automated tests.

I had hoped that libyaml would be more widely accepted than syck
by now, but OSSification seems to be rampant.

So getting an abstraction layer into rpmio on top of both syck/yaml
will be needed before rpm can routinely use a YAML parser.
