Madeleine question: auto-pruning snapshot files?

Is there a way to tell Madeleine to keep no more than X number of
snapshot files around? I've been trying it out, but noticed that, over
time, much disk space can get filled with snapshot files.

As best I can tell, each snapshot is an image of the in-memory object at
a given time. Short of the latest file getting corrupted, I'm not sure
why I would want all the snapshots generated.

The Madeleine docs give an example where yo cam specify how often to get
a snapshot, but I haven't seem anything that limits the number of files
