(Makefile): Updated comments about using LaTeX2HTML for the library

	reference.  Made the extension to the input files for makeindex
	explicit; if not made explicit a directory of the given base
	name can cause makeindex to blow up.  Specifically, if there is
	a directory ./lib/ created by LaTeX2HTML, "makeindex lib" will
	fail, but "makeindex lib.idx" will not.

	l2h{tut,ext,lib} are now dependent on myformat.perl.

	l2h adds ls2lib and removes the non-existant l2href.

-# (I've had some trouble getting this to work with the netpbm version
-# of the pbmplus library; ppmtogif dumped core because giftopnm
-# outputs bitmap (pbm) files.  I've fixed this by changing the source
-# of LaTeX2HTML to insert a call to pnmtoppm, which I wrote myself.
-# You can probably also use "pbmtopgm | pgmtoppm"...

-# In order to use these targets, you must edit the definition of L2H
-# earlier in the Makefile to point to the latex2html program.  Note
-# that LaTeX2HTML inserts references to an "icons" directory in each
-# page that it generates.  You can customize where these icons are to
-# be found; I generally make it point to "../icons" and then create a
-# symbolic link to the icons directory in the LaTeX2HTML source at the
-# appropriate place.
