 CONFIGURATION VARIABLES

 If no command line option is passed, the 'help.format' configuration
 variable will be checked. The following values are supported for this

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
 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].

+is chosen. 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.
+* "konqueror": use 'kfmclient' to open the man page in a new konqueror
+tab (see 'Note about konqueror' below).
+
+Values for other tools can be used if there is a corresponding
+'man.<tool>.cmd' configuration entry (see below).
+
+Multiple values may be given to the 'man.viewer' 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.
+
+man.<tool>.path
+~~~~~~~~~~~~~~~
+
+You can explicitly provide a full path to your preferred man viewer by
+setting the configuration variable 'man.<tool>.path'. For example, you
+can configure the absolute path to konqueror by setting
+'man.konqueror.path'. Otherwise, 'git help' assumes the tool is
+available in PATH.
+
+man.<tool>.cmd
+~~~~~~~~~~~~~~
+
+When the man viewer, specified by the 'man.viewer' configuration
+variables, is not among the supported ones, then the corresponding
+'man.<tool>.cmd' configuration variable will be looked up. If this
+variable exists then the specified tool will be treated as a custom
+command and a shell eval will be used to run the command with the man
+page passed as arguments.
+
+Note about konqueror
+~~~~~~~~~~~~~~~~~~~~
+
+When 'konqueror' is specified in the 'man.viewer' configuration
+variable, we launch 'kfmclient' to try to open the man page on an
+already opened konqueror in a new tab if possible.
+
+For consistency, we also try such a trick if 'man.konqueror.path' is
+set to something like 'A_PATH_TO/konqueror'. That means we will try to
+launch 'A_PATH_TO/kfmclient' instead.
+
+If you really want to use 'konqueror', then you can use something like
+the following:
+
+------------------------------------------------
+       [man]
+               viewer = konq
+
+       [man "konq"]
+               cmd = A_PATH_TO/konqueror
