    1.11 +# Script to time mozilla startup.
    1.12 +# Feeds in start time as url argument, startup-test.html
    1.13 +# takes this arg and computes the time difference.
    1.14 +# So something like this happens:
    1.15 +#
    1.16 +# mozilla file:/foo/startup-test.html?begin=T
    1.17 +#   where T = ms since 1970, e.g.:
    1.18 +# mozilla file:/foo/startup-test.html?begin=999456977124
    1.19 +# 
    1.20 +# NOTE: You will get much better results if you install the
    1.21 +# Time::HiRes perl module (urls in gettime.pl) and test
    1.22 +# an optimized build.
    1.23 +#
    1.24 +# For optimized builds, startup-test.html will also dump
