A system-wide installation of the Pepper Flash plugin is available from Adobe
for Windows and Mac OS X platforms as a separate download. To enable automatic
detection and loading of the system-wide installation pass the
`--enable-system-flash` command-line flag.
The Pepper Flash plugin can also be loaded by specifying the file path and
version via the `--ppapi-flash-path=<path> --ppapi-flash-version=<version>`
command-line flags. The version can be identified by viewing the
manifest.json file in the same directory as the Pepper Flash plugin library.
