48 * This routine reports errors and such via stderr and syslog() if

50 * from being scattered throughout the code.
51 *
52 * The syntax is identical to syslog(3), but %m is not considered special
53 * for output to stderr (i.e. you'll see "%m" in the output. . .).  Also,
54 * control strings should normally end with \n since newlines aren't
55 * automatically generated for stderr output (whereas syslog strips out all
56 * newlines and adds its own at the end).
