 GLib-style interface to binder (Android IPC mechanism)
+
+Key features:
+
+1. Integration with GLib event loop
+2. Detection of 32 vs 64 bit kernel at runtime
+3. Asynchronous transactions that don't block the event thread
+4. Stable service manager and low-level transation APIs
+
+Android keeps changing both low-level RPC and service manager
+protocols from version to version. To counter that, libgbinder
+implements configirable backends for different variants of those,
+and yet keeping its own API unchanged.
+
+Configuration is loaded from [Protocol] and [ServiceManager] sections
+of /etc/gbinder.conf file. The keys are binder device names or the
+special Default value, the value is the identifier of the protocol
+or service manager variant, respectively.
+
+In addition to reading /etc/gbinder.conf if it exists, /etc/gbinder.d
+directory is scanned for .conf files, the file list is sorted, files are
+loaded one by one, overwriting the entries loaded from /etc/gbinder.conf
+or from the previously processed file.
+
+Known protocol and service manager variants are aidl, aidl2 and hidl.
+This list is expected to expand further in the future. The default
+configuration is as follows:
+
+  [Protocol]
+  Default = aidl
+  /dev/binder = aidl
+  /dev/hwbinder = hidl
+
+  [ServiceManager]
+  Default = aidl
+  /dev/binder = aidl
+  /dev/hwbinder = hidl
+
+Alternatively, one can specify the desired Android API level:
+
+  [General]
+  ApiLevel = 29
+
+and let libgbinder pick the appropriate preset.

+ * Different versions of Android come with different flavors of service
+ * managers. They are usually based on these two more or less independent
+ * variants:
+ *
+ *   platform/frameworks/native/cmds/servicemanager/ServiceManager.cpp
+ *   platform/system/hwservicemanager/ServiceManager.cpp
+ *
+ * They are talking slightly different protocols which slightly mutate
+ * from version to version. If that's not complex enough, different
+ * kinds of service managers can be running simultaneously, serving
+ * different binder devices. Specific device => servicemanager mapping
+ * can be optionally configured in /etc/gbinder.conf file. The default
+ * service manager configuration looks like this:
+ *
+ *   [ServiceManager]
+ *   Default = aidl
+ *   /dev/binder = aidl
+ *   /dev/hwbinder = hidl
