X11 miscellaneous utility library headers libXmu and libXmuu are miscellaneous utility libraries for X library developers to abstract some common functions. This package provides the headers for both libraries (as libXmuu is a subset of libXmu), and is depended upon by both. For more information, please see libxmu-dev or libxmuu-dev.
