# Do a command, log it to $seq.full, optionally test return status

# and die if command fails. If called with one argument _do executes the

# command, logs it, and returns its exit status. With two arguments _do

# first prints the message passed in the first argument, and then "done"

# or "fail" depending on the return status of the command passed in the

# second argument. If the command fails and the variable _do_die_on_error

# is set to "always" or the two argument form is used and _do_die_on_error

# is set to "message_only" _do will print an error message to

# $seq.out and exit.
