section 0: where you should look for ML documentation
------------------------------------------------------------------------------

You can find the latest ML User's Guide in the subdirectory

   ml/doc/mlguide.pdf.

This address also contains up-to-date doxygen documentation. 
You can create a local Doxygen documentation as follows:

   $ cd Trilinos/ml/doc
   $ doxygen

Doxygen files mainly refer to the C++ interface of ML, and discuss several
examples in detail.

An history of ML changes is contained in the file ChangeLog.


------------------------------------------------------------------------------
section 1: configuring and compiling ML
------------------------------------------------------------------------------


------------------------------------------------------------------------------
section 2: testing ML
------------------------------------------------------------------------------

Once ML is compiled, a simple sanity check can be performed as follows:

   $ cd <your-ml-build-directory>
   $ cd examples
   $ ../test/scripts/daily/mpi/TestExamples.exe

The test will execute a subset of the examples and save the results to a log
file in ml/examples.
