.SH DIAGNOSTICS
.
All tools return a status code of zero on success or non-zero on failure.
+The non-zero codes distinguish only between the broad categories of
+unrecognised commands, problems processing the command line arguments
+and any other failures. As LVM remains under active development, the
+code used in a specific case occasionally changes between releases.
+Message text may also change.
