-== <code>$SAFE</code>
-
-Ruby provides a mechanism to restrict what operations can be performed by Ruby
-code in the form of the <code>$SAFE</code> variable.
-
-However, <code>$SAFE</code> does not provide a secure environment for executing
-untrusted code.
-
-If you need to execute untrusted code, you should use an operating system level
-sandboxing mechanism. On Linux, ptrace or LXC can be used to sandbox
-potentially malicious code. Other similar mechanisms exist on every major
-operating system.
