Multifile Documents
===================
The following is relevant when working with documents spread over
many files:
* RefTeX has full support for multifile documents. You can edit
parts of several (multifile) documents at the same time without
conflicts. RefTeX provides functions to run `grep', `search' and
`query-replace' on all files which are part of a multifile
document.
* All files belonging to a multifile document should have a File
Variable (`TeX-master' for AUCTeX or `tex-main-file' for the
standard Emacs LaTeX mode) set to the name of the master file.
See the documentation of your (La)TeX mode and *Note File
Variables: (emacs)File Variables.
* The context of a label definition must be found in the same file
as the label itself in order to be processed correctly by RefTeX.
The only exception is that section labels referring to a section
statement outside the current file can still use that section
title as context.
