Known Bugs in exim_help.

*   Hyphenated words split across lines are not
    joined back together.  They cannot be matched 
    easily.

*   This is my first attempt to really use the OO
    features of Perl5.  I would have written this
    in Python, but for the strong link between 
    Exim and Perl.  This is shown in the inelegent
    use of $main::variable all over the place, and
    maybe by other things too.

*   The program is slow to start up. But there 
    is work on a Perl compiler and Topaz (Perl 6)
    so that may change.

*   I have not thought of a way to embolden in the
    HTML output patterns which match, but overlap.
    Because several patterns may match on the same
    line, this could happen.

#   Originally, (version 0.4 or less) exim_help would
    find a paragraph describing an option, but not
    print out the option name.  This was so annoying
    that I modified it (to give version 0.5) to look
    back 2 paragraphs, and if the paragraph consisted
    of only one word, then assume it is the option
    name.  This sometimes reslts in "false positives"
    so that spurious paragraphs may be printed.  I 
    could make the checking more sophisticated, but
    it would slow down the startup, which is too
    slow at present.
