#
# This perl script connects to the TreeFam database and stores
# a list of fully sequenced species in a pickle.
#
# The command-line format is:
# % perl <store_treefam_species.pl> version
# where version is the version of the TreeFam database to use.
#
#------------------------------------------------------------------#

# CHECK IF THERE ARE THE CORRECT NUMBER OF COMMAND-LINE ARGUMENTS:

$num_args                  = $#ARGV + 1;
if ($num_args != 1)
{
   print "Usage of store_treefam_species.pl\n\n";
   print "perl store_treefam_species.pl <version>\n";
   print "where <version> is the version of the TreeFam database to use.\n";
   print "For example, >perl -w store_treefam_species.pl 7\n";
   exit;
}
