I have started implementing a command line tool to interact with PSKC
data.  It uses a new library, libpskc, to do the real work.  The
features of the tool (and thus the library) that make sense initially
appears to be:

* Parse data and validate it against PSKC XML schema.

* Create PSKC data based on input parameters.

* Parse PSKC data, printing certain fields requested by user.

* Convert PSKC data to some simpler format.

I think the above should be implemented before thinking about next
steps.  I have created a branch in git for this, see:

  http://git.savannah.gnu.org/cgit/oath-toolkit.git/log/?h=features/pskc

Expect more within the next few days...

A next step would to support PSKC data protection, but I'd like to
implement the stuff above first and then re-read the relevant portion of
the RFC to evaluate what makes sense to do.
