+graylog-sidecar (is a lightweight configuration management system)
+
+Graylog Sidecar is a lightweight configuration management system for 
+different log collectors, also called Backends. The Graylog node(s)
+acts as a centralized hub containing the configurations of log
+collectors. On supported message-producing devices/hosts, Sidecar
+can run as a service (Windows host) or daemon (Linux host).

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
