-// This utility may be invoked in the following manner:
-// llvm-dis [options] - Read LLVM bytecode from stdin, write asm to stdout
-// llvm-dis [options] x.bc - Read LLVM bytecode from the x.bc file, write asm
-// to the x.ll file.
+// This tool may be invoked in the following manner:
+// llvm-abcd [options] - Read LLVM bytecode from stdin
+// llvm-abcd [options] x.bc - Read LLVM bytecode from the x.bc file
+//
// Options:
-// --help - Output information about command line switches
-// -c - Print C code instead of LLVM assembly
+// --help - Output information about command line switches
+// --details - Provide detailed analysis of individual functions
+// --dump - Dump bytecode in readable format
//
+// This tool provides analytical information about a bytecode file. It is
+// intended as an aid to developers of bytecode reading and writing software. It
+// produces on std::out a summary of the bytecode file that shows various
+// statistics about the contents of the file. If the -details option is given
+// then the output includes detailed information about each function in the
+// bytecode file. The tool is also able to print a bytecode file in a straight
+// forward text format // that shows the containment and relationships of the
+// information in the bytecode file (-dump option).
