Outputs an app cache manifest file including (recursively) all files with the
provided in the directory with the given extensions. Each html files is then
processed and a corresponding <name>-cache.html file is created, pointing at
the appropriate cache manifest file, which is saved as <name>-cache.manifest.
Example: war *.css,*.html,*.js,*.png cache.manifest foo.html bar.html
Produces: foo-cache.html, bar-cache.html, and cache.manifest
