The Yammp Conversion Tools consist only of Perl5 programs.
For installation of the Tool Set perl
version 5.004 or newer is required.
The distribution package does not contain Yammp, CHARMM or
Amber since the utilities themselves do not use either of these program
packages. However, since the output of the force field conversions is
generated specifically for CHARMM and Amber the usefulness
of these tools is expected to be rather limited if their output is
not used within CHARMM or Amber.
