-Enzo comes with a set of pre-written parameter files which are used to test Enzo. This is useful when migrating to a new machine, with different compilers, or when new versions of compilers and libraries are introduced. Also, all the test problems should run to completion, which is generally not a guarantee!

 At the top of each enzo parameter file is a line like {{{ProblemType = 23}}}, which tells enzo the type of problem. You can see how this affects enzo by inspecting {{{src/enzo/InitializeNew.C}}}. In this case, you'll find this is used:
