This is eggdoc-texinfo, which translates standard eggdoc source into Texinfo.
From there, it can be converted into .info with makeinfo, and .pdf with texi2pdf.

The extras/ directory contains some scripts which I used to perform a batch
conversion on nearly every egg I could get my hands on.  As eggdoc source files
are currently set up to output HTML, the main file of interest is
eggdoc-texinfo-shim.scm, which overrides eggdoc->html and friends with their
eggdoc->texinfo counterparts.

You can browse the converted output here:
