RE: GUI, HTTP and LynxOS

[Mario Amado Alves <maa@di.fct.unl.pt>]

I know Amaya. It is not written in Ada. To my knowledge, it is in C. It is
mostly based on the Thot library for (at least) document editing. Thot is
also writen in C. The whole thing is buggy, and Thot is not being
mantained. ---Note that these observations are made from an Ada developer
point of view. I think Amaya is a nice thing. I use it for a variety of
purposes. It is better than Netscape in many ways. But the web tools in Ada
will be even better!

So there is no "complete HTTP server". What about an "incomplete" one,
implementing a working core of HTTP? That would be a great start. I can
think of at least two already existing packages to help doing this:

1. David Wheller's package CGI.
   This works fine.
   I work with a sligthly modified version package

2. AdaSockets
   (Is it Botton's?)
   I have not tried this yet. 
   My impression of the distribution contents is that it is either too
complicated or has a lot of unecessary things (which amounts to the same
thing from a reuse point of view).

2a. Simple_Com, Lower_Level
  (By a teacher in a spanish university, I think.)
  It is interesting alternate aproach to interprocess comunication.
