+% Usage
+% ~~~~~
+%
+% This is a tentative package aiming to provide a different approach
+% for multidocument works (mainly, books with a document per chapter).
+% Unlike the \include mechanism, every subdocument is a complete LaTeX
+% document and can be typeset separately. What the package does is
+% sharing the aux files. It's still an alpha version, and no attempt
+% has been done yet to make it to work with, say, hyperref.
+%
+% This approach has the following advantages:
+% 1) Packages can be loaded just when a part requires them.
+% 2) Generated pdf/dvi/ps files are kept.
+%
+% You need a driver tex file containing a \subdocuments command
+% listing the files. With an optional argument you can set
+% its behaviour:
+%
+% \subdocuments[clear=double]{file1, file2, file3}
+%
+% The option clear=double adds an empty page at the end to give a even
+% number of pages. clear=single doesn't and it's the default. Spaces
+% and new lines before and after commas are ignored, as well as empty
+% items. It relies on the keyval package, so names containing = must
+% be given within braces.
+%
+% This file can be used as a shared preample, with common settings
+% for all the documents.
+%
+% Documents must have the folowing line:
+%
+% \usepackage[master]{subdocs}
+%
+% where master is the name of the file described above.
+%
+% Since every subdocument reads all the aux files, \tableofcontents
+% may be used where desired.

+% A "recursive" call. When a \jobname.aux file is
+% read the first thing is (or should be) \sdoc@readaux.
+% It reads all the aux files, and exits from the current
+% aux without further reading because it is already read.
+% This requires a file could \input itself, but, does
+% that work in all distributions?
