# Fact: kernelrelease
#
# Purpose: Return the operating system's release number.
#
# Resolution:
#   On AIX returns the output from the "oslevel -s" system command.
#   On Windows based systems, uses the win32ole gem to query Windows Management
#   for the 'Win32_OperatingSystem' value.
#   Otherwise uses the output of "uname -r" system command.
#
# Caveats:
#
