Thanks, this was just what I was looking for.  Borrowing from this 
example, it seems that the require string is the path of the gems .rb 
file, starting from the /lib/ folder inside the Ruby installation.  In 
the case of the pdf-writer gem, it is /lib/pdf/witer, so the require is 
pdf/writer/, just like you said.  And you're right, it does appear in 
the docs :)
