+Controler AAAA(AGL Advance Audio Controler) and more.
+------------------------------------------------------------
+
+ * Object: Generic Controler to handle Policy,Small Business Logic, Glue in between components, ...
+ * Status: Release Candidate
+ * Author: Fulup Ar Foll fulup@iot.bzh
+ * Date : August-2017
+
+## Functionalities:
+ - Create an application dedicate controller from a JSON config file
+ - Each controls (eg: navigation, multimedia, ...) is a suite of actions. When all actions succeed control is granted, if one fail control acces is denied.
+ - Actions can either be:
+ + Invocation to an other binding API, either internal or external (eg: a policy service, Alsa UCM, ...)
+ + C routines from a user provider plugin (eg: policy routine, proprietary code, ...)
+ + LUA script function. LUA provides access to every AGL appfw functionalities and can be extended from C user provided plugins.
+
+## Installation
+ - Controler is a native part of AGL Advance Audio Framework but may be used independently with any other service or application binder.
+ - Dependencies: the only dependencies are audio-common for JSON-WRAP and Filescan-utils capabilities.
+ - Controler relies on LUA-5.3, when not needed LUA might be removed at compilation time.
+
+## Config
+
+Configuration is loaded dynamically during startup time. The controller scans CONTROL_CONFIG_PATH for a file corresponding to pattern
+"onload-bindername-xxxxx.json". When controller runs within AAAA binder it searches for "onload-audio-xxxx.json". First file found in the path the loaded
+any other files corresponding to the same pather are ignored and only generate a warning.
+
+Each bloc in the configuration file are defined with
+ * label: must be provided is used either for debugging or as input for the action (eg: signal name, control name, ...)
+ * info: optional used for documentation purpose only
+
+### Config is organised in 4 sections:
+
+ * metadata
+ * onload defines the set of action to be executed at startup time
+ * control defines the set of controls with corresponding actions
+ * event define the set of actions to be executed when receiving a given signal
+
+### Metadata
+
+As today matadata is only used for documentation purpose.
+ * label + version mandatory
+ * info optional
+
+### OnLoad section
+
+Defines startup time configuration. Onload may provide multiple initialisation profiles, each with a different label.
+ * label is mandatory. Label is used to select onload profile at initialisation through DispatchOneOnLoad("onload-label") API;
+ * info is optional
+ * plugin provides optional unique plugin name. Plugin should follow "onload-bindername-xxxxx.ctlso" patern
+ and are search into CONTROL_PLUGIN_PATH. When defined controller will execute user provided function context=CTLP_ONLOAD(label,version,info).
+ The context returned by this routine is provided back to any C routines call later by the controller.
+ * lua2c list of LUA commands shipped with provided plugin.
+ * require list of binding that should be initialised before the controller starts. Note that some listed requirer binding might be absent,
+ nevertheless any present binding from this list will be started before controller binding, missing ones generate a warning.
+ * action the list of action to execute during loadtime. Any failure in action will prevent controller binding from starting.
+
+### Control section
+
+Defines a list of controls that are accessible through (api="control", verb="request", control="control-label").
+
+ * label mandatory
+ * info optional
+ * privileges needed privileges to request this control
+ * action the list of actions
+
+### Event section
+
+Defines a list of actions to be executed on event reception. Even can do anything a controller can (change state,
+send back signal, ...) eg: if a controller subscribes to vehicule speed, then speed-event may ajust master-volume to speed.
+
+ * label mandatory
+ * info optional
+ * action the list of actions
+
+### Actions Categories
+
+Controler support tree categories of actions. Each action return a status status where 0=success and 1=failure.
+ * AppFw API, Provides a generic model to request other bindings. Requested binding can be local (eg: ALSA/UCM) or
+ external (eg: vehicle signalling).
+ * api provides requested binding API name
+ * verb provides verb to requested binding
+ * args optionally provides a jsonc object for targeted binding API. Note that 'args' are statically defined
+ in JSON configuration file. Controler client may also provided its own arguments from the query list. Targeted
+ binding receives both arguments defined in the config file and the argument provided by controller client.
+ * C-API, when defined in the onload section, the plugin may provided C native API with CTLP-CAPI(apiname, label, args, query, context).
+ Plugin may also create LUA command with CTLP-LUA2C(LuaFuncName, label, args, query, context). Where args+query are JSONC object
+ and context the value return from CTLP_ONLOAD function. Any missing value is set to NULL.
+ * LUA-API, when compiled with LUA option, the controller support action defined directly in LUA script. During "onload" phase the
+ controller search in CONTROL_LUA_PATH file with pattern "onload-bindername-xxxx.lua". Any file corresponding to this pattern
+ is automatically loaded. Any function defined in those LUA script can be called through a controller action. LUA functions receive
+ three parameters (label, args, query).
+
