====== Description ======
''moc'' is a command line tool included with Qt. Typically, the programmer does not interact directly with ''moc''. Instead, the project Makefile generated by ''qmake'' will specify the needed ''moc'' actions for a given project.

''moc'' stands for //meta-object compiler// and must be run on all classes in a project that descend from [[QObject]]. The result of running ''moc'' on a class is a new file with prefix ''moc_'' that is pure C++.

''moc'' is responsible for generating the code for implementing [[signal and slots]], creating the Qt [[property system]], implementing the Qt introspection mechanisms, and/or anything else that's suggested by a class' descending from [[QObject]] and using the ''[[Q_OBJECT]]'' macro.
