+ * Interface:
+ * Targ_Init Initialization procedure.
+ *
+ * Targ_End Cleanup the module
+ *
+ * Targ_List Return the list of all targets so far.
+ *
+ * Targ_NewGN Create a new GNode for the passed target
+ * (string). The node is *not* placed in the
+ * hash table, though all its fields are
+ * initialized.
+ *
+ * Targ_FindNode Find the node for a given target, creating
+ * and storing it if it doesn't exist and the
+ * flags are right (TARG_CREATE)
+ *
+ * Targ_FindList Given a list of names, find nodes for all
+ * of them. If a name doesn't exist and the
+ * TARG_NOCREATE flag was given, an error message
+ * is printed. Else, if a name doesn't exist,
+ * its node is created.
+ *
+ * Targ_Ignore Return TRUE if errors should be ignored when
+ * creating the given target.
+ *
+ * Targ_Silent Return TRUE if we should be silent when
+ * creating the given target.
+ *
+ * Targ_Precious Return TRUE if the target is precious and
+ * should not be removed if we are interrupted.
+ *
+ * Targ_Propagate Propagate information between related
+ * nodes. Should be called after the
+ * makefiles are parsed but before any
+ * action is taken.
+ *
+ * Debugging:
+ * Targ_PrintGraph Print out the entire graphm all variables
+ * and statistics for the directory cache. Should
+ * print something for suffixes, too, but...
