+\maketitle
+
+\section{Intoduction}
+
+The structure of \LaTeX\ documents doesn't allow one document to be included as a part of another (at least not without some hacking). This package tries to remove this limitation and enable the standard |\input| and |\include| commands to be used on standalone documents just as if they contained no preamble.
+
+\section{Usage}
+
+The package is loaded with the usual |\usepackage{docmute}|. It redefines the |\documentclass| command in such a way that everything between this command and the |\begin{document}| is skipped, as well as everything after the |\end{document}|. No attempts are made to analyse the actual content of the preamble. It is up to you to ensure that the main document loads all packages required by subsidiary documents.
+
+\DescribeMacro{\docmute}
+In rare cases some commands might be already present already before the |\documentclass| command. These commands would be then normally executed by the main document. You can prevent that by putting |\csname docmute\endcsname| at the top of the inputted document. The |\docmute| command has the same effect as the redefined |\documentclass|. Executing it through the control sequence forming primitive rather than directly ensures that standalone compilation is still possible.  In that case |\csname docmute\endcsname| will have the same effect as |\relax|.
+
+By default, nesting of inputted documents is not allowed, i.e. inputted documents cannot themselves input other documents. This behaviour can be changed with the package option |nested|. With this option inputted documents are surrounded by a group and nesting becomes possible. Note, that due to grouping only global macro (re)definitions will be visible in the parent document.
+
+\section{Known limitations}
+
+The |\documentclass| and/or |\csname docmute\endcsname| command  has to be in the same file as |\begin{document}|. This is due to employed preamble gobbling method, which relies on scanning for delimited macro arguments and which doesn't work across the file boundaries.
