+
+## Description
+
+Get and print value for PV(s).
+
+The values for one or multiple PVs are read and printed to stdout. The
+`DBR_...` format in which the data is read, the output format, and a
+number of details of how integer and float values are represented can be
+controlled using command line options.
+
+When getting multiple PVs, their order on the command line is retained
+in the output.
+
+## Options
+
+::: {option} -h
