Standard Library
Ruby comes ``out of the box'' with a large and useful library of modules and classes. This chapter contains a sampling of the more useful of these.
Interestingly, and unlike some of the code in later chapters, all of these libraries are written in Ruby. You'll find the source in the
lib
subdirectory of the standard Ruby distribution.
