+   options files. For the \cb{sync} command the search start directory is the
+   project directory, except for the implicit mode for which only the
+   predefined directories (system, etc) are searched in. The following options
+   files are searched for in each directory and, if found, loaded in the order
+   listed:
+
+   \
+   bdep.options
+   bdep-{sync|sync-implicit}.options # (mode-dependent)

+   --directory|-d
+   --implicit
+   --config|-c
