+/*Package strvals provides tools for working with strval lines.
+
+Helm supports a compressed format for YAML settings which we call strvals.
+The format is roughly like this:
+
+	name=value,topname.subname=value
+
+The above is equivalent to the YAML document
+
+	name: value
+	topname:
+	  subname: value
+
+This package provides a parser and utilities for converting the strvals format
+to other formats.
