*displaying as html
 Other web graphs: /home/drewp/projects/ffg-dash/test/sparqlBench.py

 % ./pstats2web /tmp/pro -o out.html

*displaying with kcachegrind
 Ubuntu packages: kcachegrind-convertors, kcachegrind

 % hotshot2calltree /tmp/pro > calltree
 % kcachegrind calltree

 see callee map of the 'parseTerm' function

*displaying with exhibit
 Check out exhibit at http://simile.mit.edu/exhibit/

 % ./pstats2web /tmp/pro -j out.js -m 60

 View profileResults.html in a browser, which reads out.js from the
 same directory.

*still looking for
- statistical profiler to leave running all the time

- at least a faster reporter (lsprof?)

- something to charge twisted deferred callbacks to their creator
   function instead of to the eventloop

- more useful filter groups in exhibit. callees? file is involved in
   top 10?
