ministg

ministg is an interpreter for a simple high-level operational semantics for the STG machine. The semantics is taken from the research paper "Making a fast curry: pushenter vs. evalapply for higher-order languages", by Simon Marlow and Simon Peyton Jones. It provides the option to trace the execution of the interpreter, rendering each step in a HTML file. This is useful for understanding the behaviour of the STG machine, and also useful for experimenting with changes to the machine. It also supports an experimental call stack tracing facility.
