  Well, if Modules is not specified in the config file, I get this error:

:~/erlang$
:~/erlang$ erl -config inets
Erlang (BEAM) emulator version 5.5.4 [source] [hipe]

Eshell V5.5.4  (abort with ^G)
1> application:start(inets).

failed to create child spec for

due to: "httpd_conf: Modules must be specified in the config file"
ok


It seems pretty clear that "Modules" is both mandatory, and must be set.

  Yes, it does.  I'm going to look at YAWS now.  I've already built it, and it compiled a .c file, so it does not look that promising so far.  There seems to be two contradictory uses of "embedded":

1. Running an application in some sort of special purpose device,
2. Running as a component of a larger application.

I'm interested in the later.  I was shocked to see that inets httpd is basically an Apache clone, so it is hard to get at the just the httpd bits.  I guess an Apache clone is useful if you want to enable a web server on your router.
