Pageload Test Component
=======================
Usage:
./firefox -tp file:///path/to/manifest.txt [-tpargs...]
See ./firefox -help for other arguments.
The manifest file should contain a list of URLs or URL fragments, one
per line. Empty lines or lines starting with # are ignored. If URL
fragments are specified, then -tpprefix must be used to give a prefix
to prepend to each line in the manifest to turn it into a complete
URL.
The result is a dump to stdout via dump() --
browser.dom.window.dump.enabled must be set to true in the profile. A
number of output formats can be specified via the -tpformat command
line option, currently 'js', 'text', and 'tinderbox' are supported.
Sample 'js' format output:
([({page:"1280x1024-PNG/index.html", value:133, stddev:20.049937655763422}),({page:"bugzilla.mozilla.org/index.html", value:233, stddev:36.66606060105176}),({page:"espn.go.com/index.html", value:117.6, stddev:1.2}),({page:"home.netscape.com/index.html", value:97.8, stddev:47.41898354035017}),])
Sample 'text' format output:

Sample 'tinderbox' format output:

__end_tp_report
Note that the minimum, maximum, stddev are not calculated; they're
always reported as NaN. (They were the minimum and maximum values of
any sampled value, and the standard deviation across all sampled
values -- not very useful.)
TODO
====
* Command line option to choose whether to run with or without browser chrome. Currently runs without.
* Tinderbox-dropping style output
* better yet would be to teach tinderbox about JSON
