* The Etc module provides access to information typically stored in
* files in the /etc directory on Unix systems.
*
* The information accessible consists of the information found in the
* /etc/passwd and /etc/group files, plus information about the system's
* temporary directory (/tmp) and configuration directory (/etc).
*
* The Etc module provides a more reliable way to access information about
* the logged in user than environment variables such as +$USER+.
*
* == Example:
*
* require 'etc'
*
* login = Etc.getlogin
* info = Etc.getpwnam(login)
* username = info.gecos.split(/,/).first
* puts "Hello #{username}, I see your login name is #{login}"
*
* Note that the methods provided by this module are not always secure.
* It should be used for informational purposes, and not for security.
*
* All operations defined in this module are class methods, so that you can
* include the Etc module into your class.
