X11 miscellaneous utility library (development headers) libXmu provides a set of miscellaneous utility convenience functions for X libraries to use. libXmuu is a lighter-weight version that does not depend on libXt or libXext; for more information, see libxmuu1. This package contains the development headers for the library found in libxmu6. Non-developers likely have little use for this package.
