40 * This modules provide an interface to libLLVMCore, which implements
41 * the LLVM intermediate representation as well as other related types
44 * Many exotic languages can interoperate with C code but have a harder time
45 * with C++ due to name mangling. So in addition to C, this interface enables
46 * tools written in such languages.
