<P>
Normally, it is best to use the <A HREF="../TS/TSSetFromOptions.html#TSSetFromOptions">TSSetFromOptions</A>() command and
then set the <A HREF="../TS/TS.html#TS">TS</A> type from the options database rather than by using
this routine. Using the options database provides the user with
maximum flexibility in evaluating the many different solvers.
The <A HREF="../TS/TSSetType.html#TSSetType">TSSetType</A>() routine is provided for those situations where it
is necessary to set the timestepping solver independently of the
command line or options database. This might be the case, for example,
when the choice of solver changes during the execution of the
program, and the user's application is taking responsibility for
choosing the appropriate method. In other words, this routine is
not for beginners.
