ching(6) -- The Book of Changes, not seen in BSD since 4.4BSD.

The C code is a complete rewrite done by Guy Harris for 4.4BSD and is
not the original from v7 at all. Unfortunately, the data file itself,
without which the rest isn't useful, was not freed until Caldera
released all of 32v a few years ago, so it was not in 4.4lite.

The data file, the ching nroff macros, and the driver script are under
Caldera or Caldera+Berkeley copyright.

I've partially redone the driver script from 4.4 (there was no point
in using a temporary file for the hexagram), which was already
partially redone from 32v. (As an aside, it is nutty that the script
needs a copyright so many times longer than the code.)

I've renamed "cno" to "castching", "phx" to "printching", (the
traditional names were opaque), and put them in /usr/libexec/ching
instead of the v7 /usr/games/ching.d. The data file and nroff macros
are in /usr/share/games/ching

+.Sh SYNOPSIS
+.Nm
+.Op hexagram
+.Sh DESCRIPTION
+The
+.Em I Ching
+or
+.Em Book of Changes
+is an ancient Chinese oracle that has been in use for centuries
+as a source of wisdom and advice.
+.Pp
+The text of the
+.Em oracle
+(as it is sometimes known) consists of sixty-four
+.Em hexagrams,
+each symbolized by a particular arrangement of six straight (\-\-\-)
+and broken (\-\ \-) lines.  These lines have values ranging
+from six through nine, with the even values indicating the broken lines.
+.Pp
+Each hexagram consists of two major sections.  The
+.Sy Judgement
+relates specifically to the matter at hand 
+.Po e.g.,
+.Dq "It furthers one to have somewhere to go."
+.Pc
+while the
+.Sy Image
+describes the general attributes of the hexagram and how they apply
+to one's own life
+.Po Do Thus the superior man makes
+.No himself strong 
+.No and untiring. Dc Pc
+When any of the lines have the values six or nine, they are moving
+lines; for each there is an appended judgement which becomes
+significant.  Furthermore, the moving lines are inherently unstable
+and change into their opposites; a second hexagram (and thus an
+additional judgement) is formed.
+.Pp
+Normally, one consults the oracle by fixing the desired question
+firmly in mind and then casting a set of changes (lines)
+using yarrow\-stalks or tossed coins.  The resulting hexagram
+will be the answer to the question.
+.Pp
+Using an algorithm suggested by S. C. Johnson, the
+.Ux
+.Em oracle
+simply reads a question from the standard input (up to an EOF) and
+hashes the individual characters in combination with the time of day,
+process id and any other magic numbers which happen to be lying around
+the system.  The resulting value is used as the seed of a random
+number generator which drives a simulated coin\-toss divination.  The
+answer is then piped through
+.Xr nroff 1
+for formatting and will appear on the standard output.
+.Pp
+For those who wish to remain steadfast in the old traditions, the
+oracle will also accept the results of a personal divination using,
+for example, coins.  To do this, cast the change and then type the
+resulting line values as an argument.
+.Pp
+The impatient modern may prefer to settle for Chinese cookies; try
+.Xr fortune 6 .
