// Creation Date: Thu Dec  6 23:09:26 PST 2001
// Last Modified: Thu Dec  6 23:09:33 PST 2001
// Filename:      ...sig/examples/all/attacksum.cpp
// Web Address:   http://sig.sapp.org/examples/museinfo/humdrum/attacksum.cpp
// Syntax:        C++; museinfo
//
// Description:   Generate a rhythmic summary of each measure by
//                generating a binary number based on note attacks.
// 
// Options   -f field numbers separated by dash for range and/or comma
//              Gives the fields to use for analysis.
//           -d Divisions per quarter note duration to provied analysis
//           -b binary form only -- do not sum number of attacks
//
// Example analysis:  400321530043204
//
// Status: Not yet finished
//
