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

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