+# EXAMPLES
+
+* ikiwiki --setup my.setup
+
+  Completly (re)build the wiki using the specified setup file.
+
+* ikiwiki --setup my.setup --refresh
+
+  Refresh the wiki, using settings from my.setup, and avoid
+  rebuilding any pages that have not changed. This is faster.
+
+* ikiwiki --setup my.setup --refresh --wrappers
+
+  Refresh the wiki, including regnerating all wrapper programs,
+  but do not rebuild all pages. Useful if you have changed something
+  in the setup file that does not need a full wiki rebuild to update
+  all pages, but that you want to immediatly take effect.

 # ENVIRONMENT
 
 * CC
 
   This controls what C compiler is used to build wrappers. Default is 'cc'.
 
+* CFLAGS
