It goes roughly like this:

* create pdfetex-main.web from all of the web and change files so you
   have a least a sane source while coding, and make a copy for future
   comparison
* find an existing command who's syntax/semantics are close to the
   one you intend to implement ("extension" is fairly useless for
   anything that actually does have an impact on typesetting, you
   probably want 'convert' or 'last_item').
* hook a new subcode into the processing of that existing command,
* add a call to primitive()
* create a code line to print_cmd_chr()
* when it builds ok, create a change file by running diff on the
   original pdfetex-main.web, and add this change file at the end
   of the change file list in pdfetex.mk

I'll see if it is possible to create a document with a bit more specific
info
