+# Adapted from https://github.com/Jonty/mailinabox/blob/solr_support/setup/solr.sh
+#
+# By default dovecot uses its own Squat search index that has awful performance
+# on large mailboxes. Dovecot 2.1+ has support for using Lucene internally but
+# this didn't make it into the Ubuntu packages, so we maintain our own
+# dovecot-lucene package in a ppa.
+
+source setup/functions.sh # load our functions
