HTML Include solves the problem that the Hypertext
Markup Language doesn't know a command for
including other files into a source file. It uses
specially styled comments to refer to other files,
which will be inserted at this position. Unlike to
the well known Server Side Include mechanism, this
tool pre-processes the HTML files, resulting in
files that have all referenced source files
directly embedded. Thus it does not depend on any
Web-server for correct appearance.
As a bonus, HTML Include also writes the current date to the "last modification" line and brower meta, which you usually forget (or do not bother) to update.
