[Swift-user] Resuming jobs when script has changed

[Mihael Hategan]

Sorry. I thought you didn't want the overhead of a copy.

If you do want them in your directory, then map "copy" explicitly to the
relevant name.

In other words:

file a <"mydir/a">;
file olda <"olddir/a">;
a = olda;

will copy olddir/a to mydir/a

but

file a;
file olda <"olddir/a">;
a = olda;

will not.
