//===-- PluginLoader.cpp - Implement -load command line option ------------===//

+// The LLVM Compiler Infrastructure
//
-// This file implements the -load <plugin> command line option processor. When
-// linked into a program, this new command line option is available that allows
-// users to load shared objects into the running program.
+// This file was developed by the LLVM research group and is distributed under

+//===----------------------------------------------------------------------===//
//
-// Note that there are no symbols exported by the .o file generated for this
-// .cpp file. Because of this, a program must link against support.o instead of
-// support.a: otherwise this translation unit will not be included.
+// This file implements the -load <plugin> command line option handler.
