To get this going in 0.8.1 - 0.9.2.1 (at least):
1. Create a file maxeml/_tags that contains the following lines:
<*.byte> : use_str, use_bigarray
<*.native> : use_str, use_bigarray
2. Run ocamlbuild maxeml/mxtrain.native
3. Run ocamlbuild maxeml/mxtest.native
You now have two executables in the carafe root directory for using the Maximum Entropy Classifer.
