-    Each setting type has its own editor. To modif any setting, double-click it,
-    either edit the field, or select your choice depending on the control. To
-    apply changes, select \uicontrol {Apply configuration changes}. This will

-    changes. If for any reason the build directory configuration is broken,
-    select \uicontrol {Wipe project}. This should fix any build directory.

+    For example, \c {--cross-file cross_file.txt}.
