+<p>This is the last LLVM release to support llvm-gcc 4.0, llvm-upgrade, and
+llvmc in its current form. llvm-gcc 4.0 has been replaced with llvm-gcc 4.2.
+llvm-upgrade is useful for upgrading llvm 1.9 files to llvm 2.x syntax, but you
+can always use an old release to do this. llvmc is currently mostly useless in
+llvm 2.2, and will be redesigned or removed in llvm 2.3.</p>
