+* --aggregate
+
+ If the [[plugins/aggregate]] plugin is enabled, this makes ikiwiki poll
+ configured feeds and save new posts to the srcdir.
+
+ Note that to rebuild previously aggregated posts, use the --rebuild option
+ along with this one. --rebuild will also force feeds to be polled even if
+ they were polled recently.
+
+* --render file
+
+ Renders a single file, outputting the resulting html. Does not save state,
+ so this cannot be used for building whole wikis, but it is useful for
+ previewing an edited file at the command line. Generally used in conjunction
+ with --setup to load in a wiki's setup:
+
+ ikiwiki --setup ~/ikiwiki.setup --render foo.mdwn
+
+* --post-commit
+
+ Run in post-commit mode, the same as if called by a [[post-commit]] hook.
+ This is probably only useful when using ikiwiki with a web server on one host
+ and a repository on another, to allow the repository's real post-commit
+ hook to ssh to the web server host and manually run ikiwiki to update
+ the web site.
+
+* --version
+
+ Print ikiwiki's version number.
+
+# CONFIG OPTIONS
+
+These options configure the wiki. Note that [[plugins]] can add additional
+configuration options of their own. All of these options and more besides can
+also be configured using a setup file.
+
+* --wikiname name
+
+ The name of the wiki, default is "wiki".
+
+* --templatedir dir
+
+ Specify the directory that [[templates|templates]] are stored in.
+ Default is `/usr/share/ikiwiki/templates`, or another location as configured at
+ build time. If the templatedir is changed, missing templates will still
+ be searched for in the default location as a fallback. Templates can also be
+ placed in the "templates/" subdirectory of the srcdir.
+
+ Note that if you choose to copy and modify ikiwiki's templates, you will need
+ to be careful to keep them up to date when upgrading to new versions of
+ ikiwiki. Old versions of templates do not always work with new ikiwiki
+ versions.
+
+* --underlaydir dir
+
+ Specify the directory that is used to underlay the source directory.
+ Source files will be taken from here unless overridden by a file in the
+ source directory. Default is `/usr/share/ikiwiki/basewiki` or another
+ location as configured at build time.
