I think it implies that the output is in a format amenable to use by
shell scripts.

DNS is primarily meant for humans; programs which aren't specifically
designed for geography or cartography won't understand DMS, so it will
have to be converted, and doing that in a shell script is messy (expr
and $((...)) only support integer arithmetic).
