It should work on both Windows and Linux, and all sorts of unices.  On
Windows, please install Cygwin and its FFTW and MPI packages prior to
building Tremolo.  Please report any build issues you encounter, so we
can fix them.

With Tremolo, you have to list all bonded interactions explicitly,
esp. the hydrogen bonds, and disulphide and salt bridges.  Typically
this can be done easily with a preparatory script (we have one but it's
not fully general, so it may need to be adjusted for the input).  This
might require some small programming efforts.

Non-bonded interactions are handled as usual: excluded within the first
three bonded neighbors, and possibly scaled for the 1-4 neighbor.

There is a graphical user interface that allows to adjust most settings,
but the atomic coordinates and connection data are so far read in via a
file only.  Also, there is unfortunately no extensive user manual yet.
