One ot the output options from RoboHelp is WebHelp Pro. Click
the link below to see RoboWizard's topic on the difference between
WebHelp and WebHelp Pro. It contains a link to John Daigle's topic
on WebHelp Pro.

Where you read RoboEngine in those topics, that is the name
of the previous version of RoboHelp Server 6.
Don't think WebHelp Pro is a must have. Many people produce
perfectly good professional help using plain WebHelp. You have to
decide if you do need the extra features. The Pro output no longer
contains the natural language search that you will see referred to
in those topics.
