+\maketitle
+
+This software is in the public domain; free of any restrictions.
+
+Two new \LaTeX\ commands, ``\cmd{\import}\marg{full\_path}\marg{file}''\\ and
+``\cmd{\subimport}\-\marg{path\_extension}\marg{file}'' are defined to input a file
+from another directory, allowing that file to find its own inputs
+(using ``\cmd{\input}'', ``\cmd{\includegraphics}'' etc.)\ in that directory.
+
+Alias command names are ``\cmd{\inputfrom}'' and ``\cmd{\subinputfrom}''.
+
+Also provided are ``\cmd{\includefrom}'' and ``\cmd{\subincludefrom}'', which are
+based on the ``\cmd{\include}'' command, rather than ``\cmd{\input}''. There are
+also ``\texttt{*}'' variants described below.
+
+For example, if a remote file ``\texttt{/usr5/friend/work/report.tex}'' has contents:
+%
+\begin{verbatim}
+My graph: \includegraphics{picture}
+\input{explanation}
+\end{verbatim}
+%
+then you can safely input that file in your own document with the command
+``\verb+\import{/usr5/friend/work/}{report}+''; the explanation and picture will
+be taken from the ``\texttt{/usr5/friend/work/}'' directory.
+
+The ``\cmd{\subimport}'' command takes a relative path instead of a full absolute
+file path, and it allows imported files to import files themselves, using
+their own directory as the root of another ``\meta{path\_extension}''. Do not use
+both ``\cmd{\import}'' and ``\cmd{\subimport}'' in the same file.
+
+For example, if a file is imported (using either command) from directory
+``\texttt{abc/}'' and that file contains the command ``\verb+\subimport{lmn/}{xyz}+'' then
+file ``\texttt{abc/lmn/xyz.tex}'' is input, and any ``\cmd{\input}'' commands in that file
+will read files from directory ``\texttt{abc/lmn/}''.
+
+Note that the sub-import path is merely appended to the current import
+path. Mistakes from this method must be rectified by ``\cmd{\import@path@fix}''.
+
+Depending on on how your \TeX\ system is configured, if a file with the
+same name as the import file exists in the current directory or in the
+\texttt{TEXINPUTS} path, that other file will be read in preference to one in the
+import directory. So here is the real behavior of the previous example:
+Given the sequence ``\verb+\import{abc/}{one}+'', ``\verb+\subimport{lmn/uvw/}{two}+'' (in
+file \texttt{one}), ``\verb+\input{three}+'' (in file \texttt{two}), \LaTeX\ first looks for \texttt{three.tex}
+in the \texttt{TEXINPUTS} search path; if not found, it tries ``\texttt{abc/lmn/uvw/three}'';
+if that doesn't exist, it tries ``\texttt{abc/three}''; if still not found, it tries
+the defined ``\cmd{\input@path}'', if there is one.
+
+To avoid searching the \texttt{TEXINPUTS} path when importing files, use the `star'
+versions of the commands: ``\cmd{\import*}'' and ``\cmd{\subimport*}''.
+
+A hook ``\cmd{\import@path@fix}'' is provided to reformat the import path
+to fit the syntax of a particular operating system. It \emph{could} be
+defined to convert unix-style path names to the local format, but
+all it does now is remove ``\texttt{][}'' from VMS sub-import directories.
+
+Presently, the paths are defined ``locally'' so input files must have
+balanced grouping.
