OnionFruit Native Libraries

Provides native libraries from the Tor website as pacakges for supported operating systems

Example Locator Script

When publishing, the correct binaries are copied directly to the output folder. If in debug or non-publish build, the files can be found under runtimes/{rid}/{arch}/native
