The citations chapter is now included in the HTML version of the user manual.

For some reason, a file named 'cite.tex' cannot be handled by latex2html.

The latex2html compilation of the user manual now ignores the \bibitem{} commands.

This is needed for the HTML version of the user manual.

Fixed a section titled 'Introduction' clashing with the intro chapter of the user manual.

Fixes for the user function icons in the HTML version of the user manual.

These icons are now placed on the correct HTML page.

Removed the text '.eps.gz' from all of the LaTeX included graphics in the user manual.

This allows latex2html to select and use the PNG images instead, producing much better graphics for
the online manual (http://www.nmr-relax.com/manual/index.html).

Fix for the graphics.fetch_icon() function for when no file format is specified.

The graphics.fetch_icon() function argument 'format' can now be set to None.

This will return the file path without the extension.

Elimination of all duplicated chapter, section and subsection titles in the user manual.

This fixes bug #20185 (https://gna.org/bugs/?20185).

The HTML files for the user manual now have longer names - this is needed for removing the duplicates.

Fix for the duplicate title finding script - the LaTeX and HTML mode alternatives are no longer mixed up.
