Imagine the following scenario. Say you have 3 files,


Where something.tex is your main file, i.e. you have statements like


inside something.tex. Now say you are working on b.tex and you want to
compile your code. What you really want is to compile something.tex
since this is your main file. So by inserting

%%% Local Variables:
%%% TeX-master: "something"
%%% End:

into b.tex, you tell the system to compile something.tex, even though
you are currently working on b.tex. Insert the same 3 lines into c.tex
(using C-c _) and you can now compile your code no matter what file you
are currently working on.

With regards to

%%% TeX-master: t


%%% TeX-master: "master"

the first line says that when you hit "compile" (C-c C-c) then it should
compile the current file whereas the second one says that it should
compile the file named "master.tex".

Hope this clarifies things a little bit :)
