+'''browse the repository in a graphical way
+
+The hgk extension allows browsing the history of a repository in a
+graphical way. It requires Tcl/Tk version 8.4 or later. (Tcl/Tk is not
+distributed with Mercurial.)
+
+hgk consists of two parts: a Tcl script that does the displaying and
+querying of information, and an extension to Mercurial named hgk.py,
+which provides hooks for hgk to get information. hgk can be found in
+the contrib directory, and the extension is shipped in the hgext
+repository, and needs to be enabled.
+
+The :hg:`view` command will launch the hgk Tcl script. For this command
+to work, hgk must be in your search path. Alternately, you can specify
+the path to hgk in your configuration file::
+
+ [hgk]
+ path=/location/of/hgk
+
+hgk can make use of the extdiff extension to visualize revisions.
+Assuming you had already configured extdiff vdiff command, just add::
+
+ [hgk]
+ vdiff=vdiff
+
+Revisions context menu will now display additional entries to fire
+vdiff on hovered and selected revisions.
