 '''browsing 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 hgk.py can be found in the hgext directory.
 
 To load the hgext.py extension, add it to your .hgrc file (you have
 to use your global $HOME/.hgrc file, not one in a repository). You
 can specify an absolute path:
 
   [extensions]
   hgk=/usr/local/lib/hgk.py
 
 Mercurial can also scan the default python library path for a file
 named 'hgk.py' if you set hgk empty:
 
   [extensions]
   hgk=
 
 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 .hgrc 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.'''
