All your system-independent infoz in one handy class.
SysInfo does a takes a very quick glance at the system it’s running on and exposes the results as YAML, JSON, CSV, or TSV. It also determines a platform identifier for the system that takes the form: VM-OS-IMPLEMENTATION-ARCHITECTURE.
ruby-unix-osx-i386 ruby-unix-osx-powerpc ruby-unix-linux-x86_64 java-win32-windows-i386 java-win32-mingw-i386
