 People who are interested in learning *why* a conventional init is so
impractical to use, and why solutions such as runsvdir feel so right,
would likely benefit from reading the following document:

(s6-svscan, documented in another page on the same site, performs the
same role as runsvdir, but can also be run directly as process 1.)
