+#!/usr/bin/env python
+"""cacheclean - a simple python script to clean up the /data/var/cache/pacman/pkg directory.
+More versatile than 'pacman -Sc' in that you can select how many old versions
+to keep.
+Usage: cacheclean {-p} {-v} <# of copies to keep>
+ # of copies to keep - (required) how many generations of each package to keep
+ -p - (optional) preview what would be deleted; forces verbose (-v) mode.
+ -v - (optional) show deleted packages.
+
+Adapted from https://github.com/graysky2/cacheclean for LinHES pacman cache directories
+and python 2.6."""
+
+# Note that the determination of package age is done by simply looking at the date-time
+# modified stamp on the file. There is just enough variation in the way package version
+# is done that I thought this would be simpler & just as good.
+# Also note that you must be root to run this script.
