This version of Spider has been changed to be able to produce a
\.{WEAVE} suitable for use with \LaTeX{} rather than plain \TeX{}.
The changes are minor and can be found by looking up ``LaTeX'' in the
index. You get the \LaTeX{} version by defining |LaTeX=1| or
something (the variable |LaTeX| should be non-null) on
the \.{awk} command line when you run Spider. The limbo part will sort
itself out for \LaTeX{} or plain when you weave this file.
