 "Thread Safe X ..."). So for example, instead of calling XOpenDisplay()
 in the code, TSXOpenDisplay() must be used. Likewise, X include files

 The code for the thread safe X wrappers is contained in the tsx11/
-directory and in include/TS*.h. To use a new (ie. not previously used) X
+directory and in include/ts*.h. To use a new (ie. not previously used) X
 function in Wine, a new wrapper must be created. The wrappers are
 generated (semi-)automatically from the X11R6 includes using the
 tools/make_X11wrappers perl script. In simple cases it should be enough
