+<h3>GCC "Emulation" Driver</h3>\r
+\r
+While the <tt>clang</tt> executable is a compiler driver that can perform code\r
+generation, program analysis, and other actions, it is not designed to be a\r
+drop-in replacement for GCC's <tt>cc</tt>. There is interest in developing such\r
+a driver for clang, but in the interim the clang source tree includes a Python\r
+script <tt>ccc</tt> in the <tt>utils</tt> subdirectory that provides some of\r
+this functionality (the script is intended to be used where GCC's <tt>cc</tt>\r
+could be used). It is currently a work in progress, and eventually will likely\r
+be replaced by a more complete driver.\r
