 # DESCRIPTION
 
-`ikiwiki` is a wiki compiler. It builds static html pages for a wiki, from
-`source` in the [[MarkDown]] language, using the specified html `templates`
-and writes it out to `destination`.
-
-# OPTIONS
+`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.
 
+* --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.
+
 * --wrapper [file]
 
-  Generate a [[wrapper]] binary that is hardcoded to do action specified by
+  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.
+
+* --setup configfile
+
+  In setup mode, ikiwiki reads the config file, which is really a perl
+  program that can call ikiwiki internal functions.
+
+  [[ikiwiki.setup]] is an example of such a config file.
+
+  The default action when --setup is specified is to automatically generate
+  wrappers for a wiki based on data in a config file, and rebuild the wiki.
+  If you only want to build any changed pages, you can use --refresh with
+  --setup.
+
+* --wrappers
+
+  If used with --setup --refresh, this makes it also update any configured
+  wrappers.
+
+* --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:
 
-  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.
+	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.
+
+* --wikiname
+
+  The name of the wiki, default is "wiki".
+
+* --templatedir
+
+  Specify the directory that the page [[templates|wikitemplates]] 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.
+
+* --underlaydir
+
+  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.
 
-* --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
+* --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 [[ikiwiki/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 blog can override
+  this default and generate a feed.
+
+* --atom, --noatom
 
-  Enable [[CGI]] mode. In cgi mode ikiwiki runs as a cgi script, and supports editing pages, signing in, registration, and displaying [[RecentChanges]].
+  If atom is set, ikiwiki will default to generating Atom feeds for pages
+  that inline a [[ikiwiki/blog]].
 
-  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.
+* --allowatom
 
-* --url http://someurl/
+  If allowatom is set, and rss is not set, ikiwiki will not default to
+  generating Atom feeds, but setting `atom=yes` in the blog can override
+  this default and generate a feed.
 
-  Specifies the url to the wiki. This is a required parameter in [[CGI]] mode.
+* --pingurl URL
 
-* --cgiurl http://someurl/ikiwiki.cgi
+  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
 
-  Specifies the url to the ikiwiki [[CGI]] script [[wrapper]]. Required when building the wiki for links to the cgi script to be generated.
+  This parameter can be specified multiple times to specify more than one
+  URL to ping.
 
-* --historyurl http://svn.someurl/trunk/\[[file]]?root=wiki
+* --url URL
 
-  Specifies the url to link to for page history browsing. In the url,

+* --diffurl URL
 
-  Specifies the url to link to for a diff of changes to a page. In the url,

+  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

+* --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 --no-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.
+
+* --getctime
+
+  Pull last changed time for each new page out of the revision control
+  system. This rarely used option provides a way to get the real creation
+  times of items in weblogs, such as when building a wiki from a new
+  Subversion checkout. It is unoptimised and quite slow. It is best used
+  with --rebuild, to force ikiwiki to get the ctime for all pages.
+
+* --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 configuration file. Since most options can be configured
+  using command-line switches, you will rarely need to use this, but it can be
+  useful for the odd option that lacks a command-line switch.
 
-  [[ikiwiki.setup]] is an example of such a config file.
+# ENVIRONMENT
+
+* CC
+
+  This controls what C compiler is used to build wrappers. Default is 'cc'.
