Changes in version 1.6:

• Changed and documented the handling of <Alt Only="LaTeX"> elements; its content is not reformatted.
• Can now handle help books with empty bibliography.
• Some technical adjustments which make it easier to use GAPDoc with HPC-GAP.
• Some cosmetic improvements, mainly for text output and markup of nested elements.
• Introduce finer distinction of <Alt>-elements for HTML with/without MathJax.
• 'StringBibXMLEntry' supports now a 'rec(MathJax := true)' option.
• Added a new utility function 'InitialSubstringUTF8String'.
• 'NormalizedNameAndKey' can now find initials from UTF-8 encoded name strings.
• The HTML manuals in Browsers with Javascript now always have the [Style] link, even if no MathJax version is generated.
• 'RunExamples' now returns 'true' or 'false'.
• Removed support for the "MathML" variant of 'GAPDoc2HTML' which was probably not used anyway.
• MakeGAPDocDoc (more precisely AddPageNumbersToSix) will no longer enter a break loop in case of an empty index (noticed by Thomas Breuer).
• New function 'LabelsFromBibTeX'. If BibTeX is available this is used to unify the labels used for citations and the ordering of the reference list in the LaTeX, text and HTML version of a GAPDoc document.
• 'ComposedDocument' now accepts also file names with absolute paths and relative to GAP roots. (Uses a new function 'FilenameGAP'.)
• Documented 'DOCCOMPOSEERROR' for 'ComposedDocument' to ignore missing chunks.
• Mention that .bib files for <Bibliography> must be in latin1-encoding, and corrected 3k+1.bib accordingly (error noticed by Bill Allombert).
• Corrected HorLine in tables without trailing | column (report and fix by Max Horn).
• Recognize document encoding in <?xml tag and in some other places case insensitively (proposed by Max Horn).
