+	option supersedes any other option.
+
+-i|--info::
+	Display manual page for the command in the 'info' format. The

+
+-m|--man::
+	Display manual page for the command in the 'man' format. This
+	option may be used to override a value set in the
+	'help.format' configuration variable.
++
+By default the 'man' program will be used to display the manual page,
+but the 'man.viewer' configuration variable may be used to choose
+other display programs (see below).
+
+-w|--web::
+	Display manual page for the command in the 'web' (HTML)
+	format. A web browser will be used for that purpose.
++
+The web browser can be specified using the configuration variable
+'help.browser', or 'web.browser' if the former is not set. If none of
+these config variables is set, the 'git-web--browse' helper script
+(called by 'git-help') will pick a suitable default. See
+linkgit:git-web--browse[1] for more information about this.
+
+CONFIGURATION VARIABLES
+-----------------------
+
+help.format
+~~~~~~~~~~~
+
+If no command line option is passed, the 'help.format' configuration
+variable will be checked. The following values are supported for this
+variable; they make 'git-help' behave as their corresponding command
+line option:
+
+* "man" corresponds to '-m|--man',
+* "info" corresponds to '-i|--info',
+* "web" or "html" correspond to '-w|--web'.
+
+help.browser, web.browser and browser.<tool>.path
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The 'help.browser', 'web.browser' and 'browser.<tool>.path' will also
+be checked if the 'web' format is chosen (either by command line
+option or configuration variable). See '-w|--web' in the OPTIONS
+section above and linkgit:git-web--browse[1].
+
+man.viewer
+~~~~~~~~~~
+
+The 'man.viewer' config variable will be checked if the 'man' format
+is chosen. Only the following values are currently supported:
+
+* "man": use the 'man' program as usual,
+* "woman": use 'emacsclient' to launch the "woman" mode in emacs
+(this only works starting with emacsclient versions 22),
+* "konqueror": use a man KIO slave in konqueror.
+
+Multiple values may be given to this configuration variable. Their
+corresponding programs will be tried in the order listed in the
+configuration file.
+
+For example, this configuration:
+
+	[man]
+		viewer = konqueror
+		viewer = woman
+
+will try to use konqueror first. But this may fail (for example if
+DISPLAY is not set) and in that case emacs' woman mode will be tried.
+
+If everything fails the 'man' program will be tried anyway.
+
+Note about git config --global
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note that all these configuration variables should probably be set
+using the '--global' flag, for example like this:
+
+------------------------------------------------
+$ git config --global help.format web
+$ git config --global web.browser firefox
+------------------------------------------------
+
+as they are probably more user specific than repository specific.
+See linkgit:git-config[1] for more information about this.
