[Swift-devel] another attempt at a getting started with provenance section (fwd)

[Ben Clifford]

I've fiddled a lot with the provenance db code to make installation and 
configuration easier; and the associated docbook page at 
http://www.ci.uchicago.edu/~benc/provenance.html to have more of a focus 
on running your own db (in either sqlite3 for a personal-sized db or in 
postgres for a larger db).

Section 2 of the above web page gives notes on importing your own log 
files into a database of your choosing, and section 3 gives some notes on 
query commands that I implemented a while ago and fixed up yesterday.

I also added some more commentary in the SQL schema, prov-init.sql, in the 
provenancedb checkout, to help with creating your own queries.

If you're going to play with this, I recommend starting with the sqlite3 
mode - that provides a substantially easier to administer low-end database 
compared to postgres.

I think this is basically the form I want the provenance db to look for 
the next few months. I plan on adding more information (i.e. more tables 
and more columns) and functionality, but largely in a backwards compatible 
way.
