//  make_app_icon_h.C
// Utility to convert *.icns file into app_icon.h file for use 
// with api/setMacIcon() in science applications.

// THIS CODE IS OBSOLETE! A better way to add an icon to science applications
// (or any Mac executable, including command-line tools) is:
// [1] Select the application in the Finder
// [2] Get Info (command-I) for the selected application
// [3] Click on the file's current icon in the top left corner of the Get Info window
// [4] Paste (command-v) the desired icon.
//
// To copy an icon from a different file:
// [a] Get Info for the source file
// [b] Click on the file's  icon in the top left corner of the Get Info window
// [c] Copy (command-c) the icon.
