Hi, is there any documentation on getting started using the Clang libraries in a project? A few months back, I had it working with the code below, but it has since broken. I looked a bit and it's non-obvious how to do this correctly (I simply want to run an ASTConsumer over a source file).

TextDiagnosticBuffer diagClient;
Diagnostic diags(&diagClient);
LangOptions opts;
opts.ObjC1 = true;
opts.ObjC2 = true;
opts.ObjCNonFragileABI = true;
opts.Blocks = true;
FileManager fm;
SourceManager sm;
HeaderSearch headers(fm);
InitHeaderSearch init(headers);
init.AddDefaultSystemIncludePaths(opts);
init.Realize();
const FileEntry* file = fm.getFile(argv[1]);
sm.createMainFileID(file, SourceLocation());
OwningPtr<TargetInfo> target(TargetInfo::CreateTargetInfo(LLVM_HOSTTRIPLE));
Preprocessor pp(diags, opts, *target, sm, headers);
ASTContext context(pp.getLangOptions(),
pp.getSourceManager(),
pp.getTargetInfo(),
pp.getIdentifierTable(),
pp.getSelectorTable(),
pp.getBuiltinInfo());
TestConsumer consumer;
ParseAST(pp, &consumer, context, false);
