 Although they would be wise not to do this, some software developers occasionally update their distfile with new changes without changing the distfile's name (e.g., it stays example-1.2.tar.gz).
 The port's `checksums` then need to be updated, but the `version` stays the same (e.g. stays at 1.2).
 So that users will see the update, the `revision` is increased, but users who already have the previous distfile would then experience a checksum mismatch.

+To avoid this, you must change `dist_subdir`.
 By default, `dist_subdir` is ${name}; change it so that it includes a subdirectory named for the version number and the distfile revision number (start at 1 and increment by 1 each time this version's distfile is stealth-updated):

 For software whose developers habitually stealth-update their software, further measures may need to be taken, such as those employed by the dcraw and molden ports.
 But ideally, convince the developers to refrain from stealth-updating.
+Any time a distfile is released to their download area, they should consider it to be immutable.

-Some software may distribute their distfile with a filename that does not contain the version number (e.g. example.tar.gz); such a port will likely change distname from its default ${name}-${version} to just ${name}. But when updating the port version, the old version's distfile will get in the way, since it has the same name.  The correct solution to this problem is to change dist_subdir.
