/**
 * Scans source directories for JavaCC grammar files. This scanner supports
 * {@link JJTreeMojo} and {@link JTBMojo} which perform timestamp checking
 * against copies of the input grammars rather than against the generated parser
 * files. Hence, the directory configured by {@link #setOutputDirectory(File)}
 * is taken to be the output directory for the timestamp files.
