 """Implements text_summary in TensorFlow, with TensorBoard support.
 
-The text_summary is basically a wrapper around the generic tensor_summary,
-and it uses a TextSummaryPluginAsset class to record which tensor_summaries
-are readable by the TensorBoard text plugin.
+The text_summary is a wrapper around the generic tensor_summary that takes a
+string-type tensor and emits a TensorSummary op with SummaryMetadata that
+notes that this summary is textual data for the TensorBoard text plugin.
