+Description: Make nxagent-specific keyboard bindings configurable
+ Replaces the hardcoded nxagent keybindings by a configurable
+ table of keybindings. The default configuration is the same as the
+ original one, to maintain compatibility. A user/administrator can either
+ specify a command line parameter, environment variable or place a file
+ in ~/.nx/config/keystroke.cfg or /etc/nx/keystroke.cfg to reconfigure
+ these keybindings.
+ .
+ The configuration file format is XML, a dependency on libxml2 is added
+ to allow parsing the configuration.

++Configurable keybindings in nxagent
++
++Keybindings in the redistributed x2go version of nxagent can now be configured
++by the user. This is done via a configuration file.
++
++File location
++-------------
++
++nxagent searches for the configuration file in the following order:
++- in the location given by the '-keystrokefile' command line parameter
++- in the location given by the NXAGENT_KEYSTROKEFILE environment variable
++- in ~/.nx/config/keystroke.cfg
++- in /etc/nx/keystroke.cfg
++
++If none of those files is accessible, the default configuration is used which
++is the same as the old, traditional nxagent keybindings.
++
++File format
++-----------
++
++The configuration file is XML with the following format:
++
++<!DOCTYPE NXKeystroke>
++<keystrokes>
++<keystroke action="fullscreen" AltMeta="1" Control="1" key="b" />
++<keystroke action="minimize" AltMeta="1" Control="1" key="space" />
++<keystroke action="minimize" key="Escape" Shift="1" />
++<keystroke action="close_session" key="F7" />
++<keystroke action="fullscreen" key="F7" Mod1="1" />
++<keystroke action="fullscreen" key="F6" Mod1="1" />
++<keystroke action="force_synchronization" key="f" />
++<keystroke action="fullscreen" key="space" Mod1="0" Mod2="0" Control="0" Shift="0" AltMeta="0" />
++</keystrokes>
++
++Each 'action' defines an action to be executed when receiving that keystroke. A
++list of possible actions is given below. Some of those actions are only
++available with debug builds of nxagent.
++
++Keys are given as a combination of 'key' and (optionally) a number of
++modifiers. The key attribute is evaluated into a X11 key via the usual
++XStringToKeysym function. A list of possible keys can be found in
++/usr/include/X11/keysymdef.h, the names are specified without the leading
++'XK_'. Evaluation is case-sensitive, so, 'space' and 'Escape' will work while
++'Space' and 'escape' won't.
++
++Modifiers are given as boolean attributes, possible modifiers are Mod1, Mod2,
++Mod3, Mod4, Control, Shift, Lock. Sensible combinations strongly depend on your
++keyboard configuration, but usually you will need Mod1 and Control. Boolean in
++this context means '0', 'false' and an unspecified attribute are false, anything
++else is considered true.
++
++Everything in this file is case-sensitive. Unknown lines are ignored.
++Keybindings are evaluated from top to bottom, so if a keybinding matches, other
++keybindings further down will be ignored. The contents of the file replaces the
++default keybindings, and only one file is read, no merging between different
++configuration files is done. This also means that an empty or invalid configuration
++file deactivates all keybindings.
++
++List of possible 'action' attributes:
++-------------------------------------
++
++close_session
++switch_all_screens
++minimize
++left
++up
++right
++down
++resize
++defer
++ignore
++fullscreen
++viewport_move_left
++viewport_move_up
++viewport_move_right
++viewport_move_down
++
++Only in builds with certain debugging options enabled, ignored otherwise:
++force_synchronization
++debug_tree
++regions_on_screen
++test_input
++deactivate_input_devices_grab
