Fingerprint

Fingerprint provides operating system utilities for profiling your host.

Fingerprint will do it’s best to determine the OS type (platform) and use the appropriate plugin to give you information.

Currently, system information consists of:

This library is early on and should be used at your own risk. The structure can and will change.
