X11 core wire protocol and auxiliary headers This package provides development headers describing the wire protocol for the core X11 protocol, and also provides a number of utility headers, used to abstract OS-specific functions. This package deprecates 'x-dev', a package from the monolithic builds of XFree86 and X.Org. More information about X.Org can be found at: <URL:http://www.X.org> <URL:http://xorg.freedesktop.org> <URL:http://lists.freedesktop.org/mailman/listinfo/xorg> This package is built from the X.org xproto proto module.
