That makes sense. I probably only ran the command accidentally. After
having a quick look at the code of that command, I think it just
recursively parses all installed style files, in the same way how AUCTeX
can parse the file that the user is editing.

Hm, the documentation seems to be not very explicit about how parsing is
done, other than it "can be somewhat slow". I am not surprised though
that parsing (apparently) doesn't honour case distinctions, as TeX is a
very complicated (even Turing complete AFAIK) language.

Thanks for linking to the thread. In my imagination, I visualised such a
conversation, based on the comment that was left in the code. :) I
didn't know pstricks, and consequently I didn't know that it doesn't
support pdftex.

OK, so should there be a style hook for the standalone package? It turns
out that the following code already runs the style hook for tikz (and
*not* for pstricks), since "tikz" is provided as a class option. (It
also tries to run a style hook for "border=5pt", but there is none).

Thanks to you all
