# You will need to enable Clustalw to find the clustalw program. This
# can be done in (at least) two ways:
#
# 1. define an environmental variable CLUSTALDIR:
# export CLUSTALDIR=/home/peter/clustalw1.8
#
# 2. include a definition of an environmental variable CLUSTALDIR in
# every script that will use Clustal.pm.
# $ENV{CLUSTALDIR} = '/home/peter/clustalw1.8/';
