# How can I make a PDF of the source of pdftex?

I got the files tex.web and pdftex.web from the texlive svn repo. I ran

weave tex.web
pdftex tex.tex

which produced a file tex.pdf with a nicely typeset, cross-referenced listing of the WEB source of TeX.

However, if I do the same process pdftex.web, the resulting file pdftex.pdf only contains the pages corresponding to the index.

Is there some other combination of commands I need to run, or do I need to edit part of pdftex.web? I tried weaving in the supplied .ch files, but it didn't seem to make a difference.
