not really. Here's a quick overview. The configure script and makefiles know about 3 directories:


The WWW tree was originally the w3c library. That's where the networking is done, the SGML parsing done. Over in src are the HTML parsing (on top of the SGML) and the layout onto the screen. src/chrtrans builds the compiled-in character-set tables used to make approximations to different types of display. Many of the localized messages are defined in the
top-level LYMessages_en.h

The configure script (--help) and INSTALLATION files document lynx from the standpoint of building and installing. For _modifying_ the code, there's no concise description. When I'm making changes to it, having a general sense of where things are helps. Also, running "lynx -trace" logs a lot of information to $HOME/Lynx.trace (and grep'ing for strings from the trace file does help find things).

I'd expect you'll make changes to accommodate networking quirks, e.g,
in WWW/Library/Implementation/www_tcp.h (which, along with HTUtils.h) is one of the principal places that platform-tweaks are made. The ones that can be derived from a configure-script check are of course made there...
