+# spec to build netdata RPM for sles 11
+
+Based on [opensuse rpm spec](https://build.opensuse.org/package/show/network/netdata) with some 
+changes and additions for sles 11 backport, namely:
+- init.d script 
+- run-time dependency on python ordereddict backport
+- patch for netdata python.d plugin to work with older python
+- crude hack of notification script to work with bash 3 (email and syslog only, one destination,
+  see comments at the top)
