// display some server status via HTTP/HTML (there must be some
// uncommented lines in httpd.conf). However, the page sent to
// browser is a bit raw, completely unstyled, and hard to read.
// This script tries to make that page much prettier and more
// readable. It has been tested with Apache 2.0.55 and 2.2.21 and
// should work on most versions, unless the generated HTML changes,
// which will degrade gradually the script.
