The LIBMAA library provides many low-level data structures which
are helpful for writing compilers, including hash tables, sets, 
lists, debugging support, and memory management.  Although LIBMAA
was designed and implemented as a foundation for the Khepera
Transformation System, the data structures are generally applicable
to a wide range of programming problems.  The memory management 
routines are especially helpful for improving the performance of 
memory-intensive applications.
