All warning messages are given a level --- the lower the level the greater the severity. This parameter controls the -level of messages to be seen, with all warnings of value {\tt <level>} or higher printed to standard out. The default is a warning level of 1, with -0 indicating that only those messages which are (by default) fatal should -be seen. +level of messages to be seen, with all warnings of level $\le$ {\tt <level>} +printed to standard output (warnings with level $>$ {\tt <level>} are +silently discarded). The default is a warning level of~1, +meaning that only level~0 and level~1 messages should be printed. \item [{\tt -E<level} or {\tt -error-level=<level>}] -This works in concert with {\tt -W} --- it controls which warning level is -treated as a fatal error. This cannot be set to a higher value than -{\tt -W}.
