+* --numbacklinks n
+
+ Controls how many backlinks should be displayed at the bottom of a page.
+ Excess backlinks will be hidden in a popup. Default is 10. Set to 0 to
+ disable this feature.
+
+* --userdir subdir
+
+ Optionally, allows links to users of the wiki to link to pages inside a
+ subdirectory of the wiki. The default is to link to pages in the toplevel
+ directory of the wiki.
+
+* --htmlext html
+
+ Configures the extension used for generated html files. Default is "html".
+
+* --timeformat format
+
+ Specify how to display the time or date. The format string is passed to the
+ strftime(3) function.
+
+* --verbose, --no-verbose
+
+ Be verbose about what is being done.
+
+* --syslog, --no-syslog
+
+ Log to syslog(3).
+
+* --usedirs, --no-usedirs
+
+ Toggle creating output files named page/index.html (default) instead of page.html.
+
+* --prefix-directives, --no-prefix-directives
+
+ Toggle new '!'-prefixed syntax for preprocessor directives. ikiwiki currently
+ defaults to --prefix-directives.
+
+* --w3mmode, --no-w3mmode
+
+ Enable [[w3mmode]], which allows w3m to use ikiwiki as a local CGI script,
+ without a web server.
+
+* --sslcookie
+
+ Only send cookies over an SSL connection. This should prevent them being
+ intercepted. If you enable this option then you must run at least the
+ CGI portion of ikiwiki over SSL.
+
+* --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 options 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
+
+ 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'.
