+#
+# This is a Unix Bourne shell script that counts the characters and
+# spaces in a LaTeX document by running it through LaTeX using
+# wordcount.tex, and then counting the lines in the resulting
+# wordcount.log file that match a special pattern. It assumes that you
+# have a program "grep" with a -c option meaning "Report the number of
+# matching lines". To use perl or some other tool instead of grep,
+# redefine $COUNT in some suitable way, below.
+#
+# The characters that are counted with this method are actual font
+# characters in the page body (excluding running heads): in math, each
+# subscript and superscript character is counted separately, even when
+# they appear one over the other; and so are the separate combining
+# pieces used to make large delimiters. Interword spaces are counted as
+# separate characters, and so are the spaces around mathrel symbols in
+# math formulas (equal signs and the like)---but not the spaces around
+# mathbin symbols (plus, minus, and the like).
+# 
+# You can count words by dividing the character count by 5 (or
+# whatever), or by counting the occurrences of interword spaces. The
+# latter method (illustrated here) is highly accurate at counting the
+# actual number of words---until tables or math formulas enter the
+# picture. In the case of tables, the number of words will tend to be
+# overestimated because tabskip glue, counted as an interword space,
+# appears on both sides of each table cell. (Not counting the tabskip
+# glue at all would result in an underestimate, and the underestimate
+# would tend to be slightly less accurate than the overestimate that we
+# have chosen to do.)
+#
+# And of course, in the case of math formulas, how do you define what is
+# a "word"?
