Changes to preview.sty should be upwards-compatible. In order to
facilitate updating preview-latex-style without requiring an update of
AUCTeX, I think ">=$SourceVersion" would be quite safe.
">=$someversion" would require manual maintenance, of course.
preview-latex contains the variable
preview-default-preamble is a variable defined in
`/usr/share/emacs-snapshot/site-lisp/auctex/preview.elc'.
Its value is
("\\RequirePackage["
("," . preview-default-option-list)
"]{preview}[2004/11/05]")
Documentation:
*Specifies default preamble code to add to a LaTeX document.
If the document does not itself load the preview package, that is,
when you use preview on a document not configured for preview, this
list of LaTeX commands is inserted just before \begin{document}.
You can customize this variable.
[back]
This is supposed to specify the required >= version information.
However, I think it is not a sensible idea to let preview-latex-style
fall back behind the version of auctex by default: people updating
auctex will expect to get the whole bundle (and all fixes) with a
current version. So ">= $SourceVersion" seems like a better idea than
">= $bareminimum".
An alternative is to compile the auctex package with a
"--without-texmf-dir" configure setting in which case the
preview-latex-style package would be independent of auctex, since
auctex would then use its own private version.
