/* Mac-specific code to display custom icon for science application (optional)
adapted from code written by Bernd Machenschalk. Used with permission of the
Einstein@home project.
To use this code:
1. Create a *.icns file using "/Developer/Applications/utilities/Icon Composer.app"
2. Convert the *.icns file to an app_icon.h file as follows: in Terminal, run
"MakeAppIcon_h <source_file> <dest_file>". (The MakeAppIcon_h command-line utility
is built by the Mac boinc XCode project.)
3. In the science application's main(), #include "app_icon.h" and call:
setMacIcon(argv[0], MacAppIconData, sizeof(MacAppIconData));
4. Science application must link with Carbon.framework.
