+# == Type: adblockplus::log::tracker
+#
+# Establish monitoring for a single log-file source on the current node,
+# connected to the adblockplus::log::forwarder output, if any.
+#
+# === Parameters:
+#
+# [*ensure*]
+#   Whether the tracker is supposed to be 'present' or 'absent', defaults
+#   to $adblockplus::log::ensure.
+#
+# [*format*]
+#   Either the name of a pre-configured format specific to the (Fluentd)
+#   system setup or a regular expression with named groups for extracting
+#   the log event's properties.
+#
+# [*name*]
+#   Translates literally into a tag attached to the tracked log event.
+#
+# [*path*]
+#   The full path to the log file being tracked, required to be unique.
+#
+# === Examples:
+#
+#   adblockplus::log::tracker {'example1':
+#     format => 'nginx',
+#     name => 'foobar.access',
+#     path => '/var/log/nginx/access.log',
+#   }
+#
+#   adblockplus::log::tracker {'example2':
+#     path => '/var/log/nginx/error.log',
+#     name => 'foorbar.error',
