X11 Record extension library (development headers) libXtst provides an X Window System client interface to the Record extension to the X protocol. The Record extension allows X clients to synthesise input events, which is useful for automated testing. This package contains the development headers for the library found in libxtst6. Non-developers likely have little use for this package. More information about X.Org can be found at: <URL:http://xorg.freedesktop.org> <URL:http://lists.freedesktop.org/mailman/listinfo/xorg>
