 Here are some ideas that could be use to ease backwards compatibility:
 
-* A new servlet version for module servlets that puts an old contract on the return from start.

 Footnotes:
 
 1. response/port was present for about a week, so no compatibility is provided.
 
-2. If anyone can suggest a good way to provide a compatibility layer without duplicating code, I'm interested. The problem is that web-server/insta walks the module source to find the "start" function, and we'd presumably want to overwrite that. Plus, web-server/insta will import other bindings that now have imcompatibilities.

+Each directory contains a mirror of the Web Server top-level as it was before a backwards incompatible change.

+For example, to get the version of web-server/servlet/web before backwards incompatible change 0, require web-server/compat/0/servlet/web.

+Each directory also contains a README describing the changes and the compatibility interface.

+These are not documented in the manual to discourage new programs written to the old interface.
