Indicating Differences between Document Versions  

L^ATEX2HTML supports the L^ATEX2_e changebar.sty package, written by Johannes Braams <JLBraams@cistron.nl> , for inserting change-bars in a document in order to indicate differences from previous versions. This is a very primitive form of version control and there is much scope for improvement.  
^96.1f
Within the L^ATEX version of this manual two thicknesses of change-bar have been used. Thicker bars indicate changes introduced with version V97.1, while thinner bars indicate earlier additions since V96.1.
Within the HTML version the change-bars clearly indicate the different revisions with explicit numbering.

97.1</sup>
Within the HTML version, the graphic icons representing the changebars can be followed by some text indicating the new version. This is used repeatedly throughout this manual. It is achieved using the command \cbversion{<version>}, immediately following the \begin{changebar}. This sets a variable $cb_version to be used both at the beginning and end of the environment. The value of this variable is retained, to be used with other changebar environments, unless changed explicitly by another occurrence of $cb_version.
^97.1

Warning: L^ATEX2HTML will not correctly process changebar environments that contain sectioning commands, even when the (sub)sections or (sub)paragraphs are to occur on the same HTML page. If this is required, use a separate changebar environment within each (sub)section or (sub)paragraph.
