extracted from source files that have been modified since the help resource
file was last generated. This significantly speeds up builds where only a few
source files have been modified, at the expense of making clean builds take
slightly longer. Here's some performance data gathered by testing the old and
new versions of extracthelp in isolation and averaging across 10 runs:
old extracthelp, 1 modified source file: 20.1 seconds
new extracthelp, 1 modified source file: 7.2 seconds <-- woohoo! :)
old extracthelp, clean build: 17.8 seconds
new extracthelp, clean build: 20.5 seconds
