"polipo_trimcache"  [AKA "polipo-trimcache"]  is a  Polipo maintenance
tool.

The original author described "polipo_trimcache" as follows:

"Polipo doesn't have any  built-in facility for keeping its cache dir-
ectory under a given fixed size. This script implements that: it trims
your cache directory to a target size by removing the files  with old-
est access times until the cache size is smaller  than or equal to the
target size."

This tool was obtained originally from:
