+ZooKeeper is a centralized service for maintaining configuration information,
+naming, providing distributed synchronization, and providing group services. 
+All of these kinds of services are used in some form or another by distributed 
+applications. Each time they are implemented there is a lot of work that goes 
+into fixing the bugs and race conditions that are inevitable. Because of the 
+difficulty of implementing these kinds of services, applications initially 
+usually skimp on them ,which make them brittle in the presence of change and 
+difficult to manage. Even when done correctly, different implementations of 
+these services lead to management complexity when the applications are 
+deployed.
+
+This script requires a 'zookeeper' user/group to exist before running. 
+The recommended UID/GID is 322. You can create these like so:
+
+groupadd -g 322 zookeeper
+useradd -u 322 -g 322 -c "Zookeeper user" -d /var/lib/zookeeper -s /bin/sh zookeeper

+# 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.
