+Source: fswarn
+Maintainer: Joe Rayhawk <jrayhawk@omgwallhack.org>
+Section: admin
+Build-depends: debhelper (>= 7)
+Priority: extra
+Homepage: http://piny.be/fswarn/
+Standards-version: 3.9.1
+
+Package: fswarn
+Architecture: all
+Depends: ${misc:Depends}
+Recommends: mail-transport-agent, cron
+Description: cron.hourly filesystem utilization check 
+ Prints warnings of utilization of total blocks or inodes over a configurable
+ percentage threshold.
+ .
+ fswarn relies on the MAILTO function of cron. An MTA should probably be
+ present and operational for this to do anything useful.
