pkgdb usage guide

[Vizion]

Hi

It would be most appreciated if someone who is familiar with the use of pkgdb 
could either point to a user guide that tells one how & in what circumstances 
to use the various interactive options offered by this utility or maybe help 
to draft an faq on it.

Thanks
