libxmuu1 6.8.2-10.3 (amd64 binary) in ubuntu hoary

 libXmuu is a very small set of miscellaneous utility functions extracted
 from Xmu, Xt, and Xaw. This library is intended for X clients that need the
 occasional useful function from these libraries but do not require the
 toolkit overhead. To use libXmuu, simply include the headers for the other
 libraries in the client and link against Xmuu instead of Xmu, Xt, and Xaw.
 Needless to say, if the client uses functions from Xmu, Xt, or Xaw that are
 not present in Xmuu, it will fail to link.
