// This tool may be invoked in the following manner:
// llvm-bcanalyzer [options] - Read LLVM bitcode from stdin

// This tool provides analytical information about a bitcode file. It is
// intended as an aid to developers of bitcode reading and writing software. It
// produces on std::out a summary of the bitcode file that shows various
// statistics about the contents of the file. By default this information is
// detailed and contains information about individual bitcode blocks and the
// functions in the module.
// The tool is also able to print a bitcode file in a straight forward text
// format that shows the containment and relationships of the information in
// the bitcode file (-dump option).
