From: Tzvetomir Stoyanov <tstoyanov@xxxxxxxxxx>

Initial support for libtraceevent man pages - Documentation directory,
templates, configurations, Makefiles. The first man page is also part
of the patch - summary of the library and all its APIs. Building of
the documentation is integrated into the libtraceevent build process,
new targets are added to its Makefile:
make help
make doc
make doc-clean
make doc-install
make doc-uninstall

+DESCRIPTION
+-----------
+The libtraceevent(3) library provides APIs to access kernel tracepoint events,
+located in the tracefs file system under the events directory.
+
+ENVIRONMENT
+-----------
+[verse]
+--
+TRACEEVENT_PLUGIN_DIR
+ Additional plugin directory. All shared object files, located in this directory will be loaded as traceevent plugins.
+--
+
+FILES
+-----
+[verse]
+--
+*event-parse.h*
+ Header file to include in order to have access to the library APIs.
+*trace-seq.h*
+ Header file to include in order to have access to trace sequences related APIs.
+ Trace sequences are used to allow a function to call several other functions
+ to create a string of data to use.
+*-ltraceevent*
+ Linker switch to add when building a program that uses the library.
