+/*! \file
+ * \brief
+ * This file is responsible for defining two operations that are not
+ * directly portable between Unix-like systems and Windows NT, option
+ * parsing and directory scanning.  It is here because it was decided
+ * that the "gen" build utility was not to depend on libisc.a, so
+ * the functions delcared in isc/commandline.h and isc/dir.h could not
+ * be used.
+ *
+ * The commandline stuff is really just a wrapper around getopt().
+ * The dir stuff was shrunk to fit the needs of gen.c.
