# This is a Munin plugin to report the disk usage of TileCache disk caches.
# Use it by linking with the name tilecache_cache_size_LAYERNAME

# The "standard" way to install this script for Munin is to place it in /usr/share/munin/plugins/
# and then run (replacing LAYERNAME with the TileCache layer name as in tilecache.cfg)
