+NAME
+----
+git-instaweb - Instantly browse your working repository in gitweb
+
+SYNOPSIS
+--------
+[verse]
+'git instaweb' [--local] [--httpd=<httpd>] [--port=<port>]
+               [--browser=<browser>]
+'git instaweb' [--start] [--stop] [--restart]
+
+DESCRIPTION
+-----------
+A simple script to set up `gitweb` and a web server for browsing the local
+repository.
+
+OPTIONS
+-------
+
+-l::
+--local::
+	Only bind the web server to the local IP (127.0.0.1).
+
+-d::
+--httpd::
+	The HTTP daemon command-line that will be executed.
+	Command-line options may be specified here, and the
+	configuration file will be added at the end of the command-line.
+	Currently apache2, lighttpd, mongoose, plackup, python and
+	webrick are supported.
+	(Default: lighttpd)
+
+-m::
+--module-path::
+	The module path (only needed if httpd is Apache).
+	(Default: /usr/lib/apache2/modules)
+
+-p::
+--port::
+	The port number to bind the httpd to.  (Default: 1234)
+
+-b::
+--browser::
+	The web browser that should be used to view the gitweb
+	page. This will be passed to the 'git web{litdd}browse' helper
+	script along with the URL of the gitweb instance. See
+	linkgit:git-web{litdd}browse[1] for more information about this. If
+	the script fails, the URL will be printed to stdout.
+
+start::
+--start::
+	Start the httpd instance and exit.  Regenerate configuration files
+	as necessary for spawning a new instance.
+
+stop::
+--stop::
+	Stop the httpd instance and exit.  This does not generate
+	any of the configuration files for spawning a new instance,
+	nor does it close the browser.
+
+restart::
+--restart::
+	Restart the httpd instance and exit.  Regenerate configuration files
+	as necessary for spawning a new instance.
