description     The nhc98 Haskell Compiler
long_description \
                nhc98 is a small, easy to install, standards-compliant \
                compiler for Haskell 98, the lazy functional \
                programming language. It is very portable, and aims \
                to produce small executables that run in small amounts \
                of memory. It produces medium-fast code, and compilation \
                is itself quite fast. It also comes with extensive tool \
                support for automatic compilation, foreign language \
                interfacing, heap and time profiling, tracing \
                and debugging. Some of its advanced kinds of heap \
                profiles are not found in any other Haskell compiler.
