Marsh,
that's what I thought. I face a similar problem and have not found a
solution either. For a bunch of web sub/domains a good deal of
stock graphics, style sheets, script function libraries is *almost*
identical, except for minor differences as adjustments to the
specific site, e.g. color of graphics, backgrounds, font size/style,
configuration values. So any time something in the actual
functions is changed I have to go through a dozen and more files.
With a graphic diff/merge tool like Winmerge it is not too bad, but
yet.
One other thing which might work for you or make things even
worse as the source becomes less readable and less easy to test
would be to employ some script language (e.g. PHP) to decide
which parts of the documents are displayed at a given time. PHP
could calculate this based on a date function or just by the value of
a variable stored in a central config file. I do something like this by
way of a function to display some web pages changing every
month and some images changing by the season. However, in the
former case completely different, separate files are pulled into kind
of a template, while in the latter case the images are just one short
list in the document, so there is little chance of confusion.
