+// Package view contains support for collecting and exposing aggregates over stats.
+//
+// In order to collect measurements, views need to be defined and registered.
+// A view allows recorded measurements to be filtered and aggregated.
+//
+// All recorded measurements can be grouped by a list of tags.
+//
+// OpenCensus provides several aggregation methods: Count, Distribution and Sum.
+//
+// Count only counts the number of measurement points recorded.
+// Distribution provides statistical summary of the aggregated data by counting
+// how many recorded measurements fall into each bucket.
+// Sum adds up the measurement values.
+// LastValue just keeps track of the most recently recorded measurement value.
+// All aggregations are cumulative.
+//
+// Views can be registered and unregistered at any time during program execution.
+//
+// Libraries can define views but it is recommended that in most cases registering
+// views be left up to applications.
+//
+// # Exporting
+//
+// Collected and aggregated data can be exported to a metric collection
+// backend by registering its exporter.
+//
+// Multiple exporters can be registered to upload the data to various
+// different back ends.
