end

#lookup(key) ⇒ Object

Returns the value of the given key for this OS. At a minimum an OS should provide the following:

name

returns the name of the OS

version

the version of the OS

osname

e.g. freebsd, linux, windows, etc - these should return true and be case insensitive to allow

lookups of the form lookup(‘Windows’)

hostname

the hostname of the machine

In addition to the above name and version should be implemented as get methods for convenience
