+* --gettime, --no-gettime
+
+ Extract creation and modification times for each new page from the
+ the revision control's log. This is done automatically when building a
+ wiki for the first time, so you normally do not need to use this option.
+
+* --set var=value
+
+ This allows setting an arbitrary configuration variable, the same as if it
+ were set via a setup file. Since most commonly used options can be
+ configured using command-line switches, you will rarely need to use this.
+
+* --set-yaml var=value
+
+ This is like --set, but it allows setting configuration variables that
+ use complex data structures, by passing in a YAML document.
+
+# EXAMPLES
+
+* ikiwiki --setup my.setup
+
+ Completely (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 regenerating 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 immediately take effect.
+
+* ikiwiki --rebuild srcdir destdir
+
+ Use srcdir as source and build HTML in destdir, without using a
+ setup file.
+
+* ikiwiki srcdir destdir
+
+ Use srcdir as source to update changed pages' HTML in destdir,
+ without using a setup file.
+
+# 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.
