       Bio::Tools::Run::Phylo::PAML::Evolver - Wrapper aroud the PAML program

         # FIXME: something similar for nucleotide frequencies:
         # Option (5) Simulate nucleotide data sets (use MCbase.dat)?

         # FIXME: something similar for aa parameters:

       This is a wrapper around the evolver program of PAML (Phylogenetic
       Analysis by Maximum Likelihood) package of Ziheng Yang.  See for more information.

       This module is more about generating the properl MCmodel.ctl file and
       will run the program in a separate temporary directory to avoid
       creating temp files all over the place.


   Mailing Lists
       User feedback is an integral part of the evolution of this and other
       Bioperl modules. Send your comments and suggestions preferably to the
       Bioperl mailing list.  Your participation is much appreciated.
              - General discussion  - About the mailing lists

       Please direct usage questions or support issues to the mailing list:

       rather than to the module maintainer directly. Many experienced and
       reponsive experts will be able look at the problem and quickly address
       it. Please include a thorough description of the problem with code and
       data examples if at all possible.

       The rest of the documentation details each of the object methods.
       Internal methods are usually preceded with a _

   Default Values
       Valid and default values for evolver programs are listed below.  The
       default values are always the first one listed.  These descriptions are
       essentially lifted from the example MCcodon.dat file and pamlDOC
       documentation provided by the author.


       option1 specifies something.

       option2 specifies something else.
