Local variables

[Dieter Britz]

In one file, a chapter out of many, when I enter emacs I get
this message on the bottom half of a split screen:

The local variable list in chap07.tex contains values
that may not be safe (*).

I then get a choice of responses. I choose "y". At the bottom
of the file I find this

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% End:

What does this mean? Why does this happen with this particular
file and not others?

That's nice, but how do they get in there? I never asked for
them, and they are evidently not in all files.

Can I just delete those three last lines and the problem is gone,
or what do I have to do?

Yes, you can delete those lines.

Someone or something has put them in there. If these are 'your' files,
most probably some Tex-Editing package "helpfully" has set them.
If you got these files from someone else, 'they' find that setting useful.

You can just delete them. Just be prepared that the next 'save' might
bring them back, if some editing package of yours has added them.
If so, you should check which package it is...

To avoid being asked, make sure that you load the latex library before you open the file.

Sometimes local variables can contain malicious code, so emacs is asking you to confirm that it is ok to load the particular local variable.
