This document describes the changes made to the Webtool application.
webtool crashed when trying to find a free
port number if connection failed with other reason than
econnrefused
debug_app/1 and some error printouts are added to
simplify debugging of own application.
Data is set to PortNumber in
start(Path,Data), the default data will be used
for ip-number (127.0.0.1) and server name
(localhost).
