If the gem generates documentation, I'd look there. Otherwise, look into 
your /usr/lib/ruby/gems/1.8/name_of_gem directories for a README or code 
code examples. In case you didn't know it gem_server launches a small 
server, which makes the RDoc documentation accessible (in case the 
developer was smart enough to include such a thing ;)

Otherwise, you might take your chances and even look at the gem's 
homepage. in this case, it probably is http://netaddr.rubyforge.org
