-// TableGen is a tool which can be used to build up a description of something,
-// then invoke one or more "tablegen backends" to emit information about the
-// description in some predefined format. In practice, this is used by the LLVM
-// code generators to automate generation of a code generator through a
-// high-level description of the target.
+// This file contains the main function for LLVM's TableGen.
