This class will yield to the user the information about all mountpoints on a Linux System. It may also work on Windows, by making use of "wmic". Please do note that on Linux this works only via "fdisk", and even then not always. This gem was initially started as a "throw-away" gem that can be used quickly, rather than having to parse the output of "fdisk -l" manually (or by eyes only). Also do note that we are only interested in external devices that are mounted that way, NOT other mountpoints. The reason for this is because this gem here serves as a foundation for backing up data onto external USB devices. For more information pertaining to this gem have a look at the official homepage of this gem.
