+* --set var=value
+
+ This allows setting an arbitrary configuration variable, the same as if it
+ were set via a setup file. Since most options can be configured
+ using command-line switches, you will rarely need to use this, but it can be
+ useful for the odd option that lacks a command-line switch.
+
+# 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
+
+ This can be used to pass options to the C compiler when building wrappers.
