+`ikiwiki` is a wiki compiler. It builds static HTML pages for a wiki, from
+`source` in the [[ikiwiki/Markdown]] language (or others), and writes it out to
+`destination`.

 
 Note that most options can be shortened to single letters, and boolean
 flags such as --verbose can be negated with --no-verbose.

-* --wikiname
+# MODE OPTIONS

 
 

-  The name of the wiki, default is "wiki".
+These options control the mode that ikiwiki operates in.

 
 

-* --verbose
+* --refresh

 
 

-  Be vebose about what it's doing.
+  Refresh the wiki, updating any changed pages. This is the default
+  behavior so you don't normally need to specify it.

 
 * --rebuild
 
   Force a rebuild of all pages.
 
 
 * --rebuild
 
   Force a rebuild of all pages.
 

+* --setup setupfile
+
+  The default action when --setup is specified is to automatically generate
+  wrappers for a wiki based on data in a setup file, and rebuild the wiki.
+  If you only want to build any changed pages, you can use --refresh with
+  --setup.
+
+* --changesetup setupfile
+
+  Reads the setup file, adds any configuration changes specified by other
+  options, and writes the new configuration back to the setup file. Also
+  updates any configured wrappers. In this mode, the wiki is not fully
+  rebuilt, unless you also add --rebuild.
+
+  Example, to enable some plugins:
+
+       ikiwiki --changesetup ~/ikiwiki.setup --plugin goodstuff --plugin calendar
+
+* --dumpsetup setupfile
+
+  Causes ikiwiki to write to the specified setup file, dumping out
+  its current configuration.
+
+* --wrappers
+
+  If used with --setup --refresh, this makes it also update any configured
+  wrappers.
+
+* --clean
+
+  This makes ikiwiki clean up by removing any files it generated in the
+  `destination` directory, as well as any configured wrappers, and the
+  `.ikiwiki` state directory. This is mostly useful if you're running
+  ikiwiki in a Makefile to build documentation and want a corresponding
+  `clean` target.
+
+* --cgi
+
+  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.

+  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

 
 

-  Note that the generated wrapper will ignore all command line parameters
-  except for --params, which will make it print out the parameters it would
-  run ikiwiki with.
+  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.
 
 
 * --wrappermode mode
 
   Specify a mode to chmod the wrapper to after creating it.
 

-* --svn, --nosvn
+* --wrappergroup group

 
 

-  Enable or disable use of [[subversion]]. If subversion is enabled, the `source` directory is assumed to be a working copy, and is automatically updated before building the wiki. 
+  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.

 
 

-  In [[CGI]] mode, with subversion enabled pages edited via the web will be committed to subversion. Also, the [[RecentChanges]] link will be placed on pages.
+* --rcs=svn|git|.., --no-rcs

 
 

-  Subversion is enabled by default.
+  Enable or disable use of a [[revision_control_system|rcs]].

 
 

-* --anonok, --noanonok
+  The `source` directory will be assumed to be a working copy, or clone, or
+  whatever the revision control system you select uses.

 
 

-  If anonok is set, it will allow anonymous web users, who have not signed in, to make changes to the wiki.
+  In [[CGI]] mode, with a revision control system enabled, pages edited via
+  the web will be committed.

 
 

-  By default, anonymous users cannot edit the wiki.
+  No revision control is enabled by default.

 
 

-* --cgi
+* --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

 
 

-  Enable [[CGI]] mode. In cgi mode ikiwiki runs as a cgi script, and supports editing pages, signing in, registration, and displaying [[RecentChanges]].
+  This parameter can be specified multiple times to specify more than one
+  URL to ping.

 
 

-  To use ikiwiki as a [[CGI]] program you need to use --wrapper to generate a wrapper. The wrapper will generally need to run suid 6755 to the user who owns the `source` and `destination` directories.
+* --url URL

 
 

-* --url http://someurl/
+  Specifies the URL to the wiki. This is a required parameter in [[CGI]] mode.

 
 

-  Specifies the url to the wiki. This is a required parameter in [[CGI]] mode.
+* --cgiurl http://example.org/ikiwiki.cgi

 
 

-* --cgiurl http://someurl/ikiwiki.cgi
+  Specifies the URL to the ikiwiki [[CGI]] script wrapper. Required when
+  building the wiki for links to the cgi script to be generated.

 
 

-  Specifies the url to the ikiwiki [[CGI]] script [[wrapper]]. Required when building the wiki for links to the cgi script to be generated.
+* --historyurl URL

 
 

-* --historyurl http://svn.someurl/trunk/[[]]?root=wiki
+  Specifies the URL to link to for page history browsing. In the URL,
+  "\[[file]]" is replaced with the file to browse. It's common to use
+  [[ViewVC]] for this.

 
 

-  Specifies the url to link to for page history browsing. In the url, "[[]]" is replaced with the page to browse. It's common to use [[ViewCVS]] for this.
+* --adminemail you@example.org
+
+  Specifies the email address that ikiwiki should use for sending email.
+
+* --diffurl URL
+
+  Specifies the URL to link to for a diff of changes to a page. In the URL,
+  "\[[file]]" is replaced with the file to browse, "\[[r1]]" is the old
+  revision of the page, and "\[[r2]]" is the new revision. It's common to use
+  [[ViewVC]] for this.

 
 * --exclude regexp
 
   Specifies a rexexp of source files to exclude from processing.
   May be specified multiple times to add to exclude list.
 
 
 * --exclude regexp
 
   Specifies a rexexp of source files to exclude from processing.
   May be specified multiple times to add to exclude list.
 

-* --setup configfile
+* --include regexp
+
+  Specifies a rexexp of source files, that would normally be excluded,
+  but that you wish to include in processing.
+  May be specified multiple times to add to include list.
+
+* --adminuser name
+
+  Specifies a username of a user (or, if openid is enabled, an openid) 
+  who has the powers of a wiki admin. Currently allows locking of any page,
+  and [[banning|banned_users]] users; other powers may be added later.
+  May be specified multiple times for multiple admins.
+
+  For an openid user specify the full URL of the login, including "http://".
+
+* --plugin name
+
+  Enables the use of the specified [[plugin|plugins]] in the wiki. 
+  Note that plugin names are case sensitive.
+
+* --disable-plugin name
+
+  Disables use of a plugin. For example "--disable-plugin htmlscrubber"
+  to do away with HTML sanitization.
+
+* --libdir directory
+
+  Makes ikiwiki look in the specified directory first, before the regular
+  locations when loading library files and plugins. For example, if you set
+  libdir to "/home/you/.ikiwiki/", you can install a foo.pm plugin as
+  "/home/you/.ikiwiki/IkiWiki/Plugin/foo.pm".
+
+* --discussion, --no-discussion
+
+  Enables or disables "Discussion" links from being added to the header of
+  every page. The links are enabled by default.
+
+* --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

 
 

-  In setup mode, ikiwiki reads the config file, which is really a perl
-  program that can call ikiwiki internal functions. Uses of this are
-  various; the normal one is to automatically generate wrappers for a
-  wiki based on data in a config file.
+  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

   
   

-  Note that the wiki will be (re)built as part of the setup process to
-  ensure that any changes take effect.
+  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 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.
+
+# SEE ALSO
