+ Enable [[CGI]] mode. In cgi mode ikiwiki runs as a cgi script, and
+ supports editing pages, signing in, and registration.
+
+ To use ikiwiki as a [[CGI]] program you need to use --wrapper or --setup
+ to generate a wrapper. The wrapper will generally need to run suid 6755 to
+ the user who owns the `source` and `destination` directories.
+
+* --wrapper [file]
+
+ Generate a wrapper binary that is hardcoded to do action specified by
+ the other options, using the specified input files and `destination`
+ directory. The filename to use for the wrapper is optional.
+
+ The wrapper is designed to be safely made suid and be run by untrusted
+ users, as a [[post-commit]] hook, or as a [[CGI]].
+
+ Note that the generated wrapper will ignore all command line parameters.
+
+* --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.
+
+* --wrappermode mode
+
+ Specify a mode to chmod the wrapper to after creating it.
+
+* --wrappergroup group
+
+ Specify what unix group the wrapper should be owned by. This can be
+ useful if the wrapper needs to be owned by a group other than the default.
+ For example, if a project has a repository with multiple committers with
+ access controlled by a group, it makes sense for the ikiwiki wrappers
+ to run setgid to that group.
+
+* --rcs=svn|git|.., --no-rcs
+
+ Enable or disable use of a [[revision_control_system|rcs]].
+
+ The `source` directory will be assumed to be a working copy, or clone, or
+ whatever the revision control system you select uses.
+
+ In [[CGI]] mode, with a revision control system enabled, pages edited via
+ the web will be committed.
+
+ No revision control is enabled by default.
+
+* --svnrepo /svn/wiki
+
+ Specify the location of the svn repository for the wiki.
+
+* --svnpath trunk
+
+ Specify the path inside your svn repository where the wiki is located.
+ This defaults to `trunk`; change it if your wiki is at some other path
+ inside the repository. If your wiki is rooted at the top of the repository,
+ set svnpath to "".
+
+* --rss, --norss
+
+ If rss is set, ikiwiki will default to generating RSS feeds for pages
+ that inline a [[blog]].
+
+* --allowrss
+
+ If allowrss is set, and rss is not set, ikiwiki will not default to
+ generating RSS feeds, but setting `rss=yes` in the inline directive can
+ override this default and generate a feed.
+
+* --atom, --noatom
+
+ If atom is set, ikiwiki will default to generating Atom feeds for pages
+ that inline a [[blog]].
+
+* --allowatom
+
+ If allowatom is set, and rss is not set, ikiwiki will not default to
+ generating Atom feeds, but setting `atom=yes` in the inline directive can
+ override this default and generate a feed.
+
+* --pingurl URL
+
+ Set this to the URL of an XML-RPC service to ping when an RSS feed is
+ updated. For example, to ping Technorati, use the URL
+ http://rpc.technorati.com/rpc/ping
+
+ This parameter can be specified multiple times to specify more than one
+ URL to ping.
+
+* --url URL
+
+ Specifies the URL to the wiki. This is a required parameter in [[CGI]] mode.
