+Mirror the distfiles of each given port and their subports.

+Options:
+
+  --distfiles-dir=<URL>
+    A directory for storing the distfiles. Defaults to the
+    \`var/macports/distfiles' subdirectory of the \`--prefix' directory. If
+    changed, deletes the \`var/macports/distfiles' directory and replaces it
+    with a symlink to the specified directory.
+
+Run \`$prog help' for global options and a list of other subcommands.
