edit-compile-link-run or edit-make-run cycle to a rapid edit-run cycle.  Like
make and other tools, rdmd uses the relative dates of the files involved to
minimize the amount of work necessary.  Unlike make, rdmd tracks dependencies
and freshness without requiring additional information from the user.")
