-Two new \LaTeX\ commands, ``\cmd{\import}\marg{full\_path}\marg{file}''\\ and

-from another directory, allowing that file to find its own inputs
-(using ``\cmd{\input}'', ``\cmd{\includegraphics}'' etc.)\ in that directory.
+\medskip
-Alias command names are ``\cmd{\inputfrom}'' and ``\cmd{\subinputfrom}''.
+Two new \LaTeX\ commands:
+\begin{verse}
+ \cmd{\import} \marg{full-path} \marg{file}\hspace{8em} and\\[2pt]
+ \cmd{\subimport} \marg{path-extension} \marg{file}
+\end{verse}
+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.
-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.
+Alias command names are ``\cmd{\inputfrom}'' and ``\cmd{\subinputfrom}''.
+(If \cmd{\import} was defined previously, it will not be redefined.)
+Also provided are the similar commands ``\cmd{\includefrom}'' and
+``\cmd{\subincludefrom}'', which are based on the \cmd{\include} command,
+rather than \cmd{\input}.
-For example, if a remote file ``\texttt{/usr5/friend/work/report.tex}'' has contents:
+For example, if a remote file \texttt{/user/friend/work/report.tex} has
+contents:
%
\begin{verbatim}
-My graph: \includegraphics{picture}
-\input{explanation}
+ 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.
-
+then you can input that file to a document with
+\verb+\import{/user/friend/+\^\verb+work/}+\^\verb+{report}+
+so that both the explanation and picture will be taken from the
+\texttt{/user/friend/\^work/} directory.
+
+The \meta{full-path} argument for \cmd{\import} can be a full absolute path
+or a relative path starting from the main working directory for the document.
+The \cmd{\subimport} command facilitates nesting of file imports. It takes a
+relative \meta{path-extension} based on the location of the current imported 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
+\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/}.\footnote{~Note that the sub-import
+ path is merely appended to the current import path. Syntactical mistakes from this
+ method may be corrected by \cmd{\import@path@fix}.}
+
+Depending on on how your \TeX\ system is configured, if a file does not
+exist in the specified import directory, it will be looked for in previous
+import directories (when nesting \cmd{\subimport} files), then in any
+directory listed in the pre-existing \cmd{\input@path}, then in the current
+working directory, and finally in the \texttt{TEXINPUTS} path. Therefore, for
+\cmd{\import} and for other \cmd{\input} used within an imported file,
+a file found on the path of import(s) will be read in preference to others with
+the same name located elsewhere. So here is the real behavior of the previous
+example: Given the nested sequence:
+\begin{verse}
+\verb+\import{abc/}{one}+\quad (in main document);\\
+\verb+\subimport{lmn/uvw/}{two}+\quad (in file \texttt{abc/one.tex});\\
+\verb+\input{three}+\quad (in file \texttt{abc/lmn/uvw/two.tex});
+\end{verse}
+\LaTeX\ first looks for \texttt{abc/lmn/uvw/three} (or \texttt{abc/lmn/uvw/three.tex});\\
+if not found, it tries \texttt{abc/three} (or \texttt{abc/three.tex});\\
+if still not found, it looks in the \cmd{\input@path}, if there was one defined;\\
+if \cmd{\input@path} was not defined, or if the file was not found on it,
+\LaTeX\ then tries to open \texttt{three} in the main document directory;\\
+finally, if still not found, it searches the \texttt{TEXINPUTS} search path.
+
+Historically, `star' versions of the commands were defined (to avoid searching
+the \texttt{TEXINPUTS} path) but now the ``$*$'' is ignored.
+
+
+A command ``\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.

+
+Note that the import package works by manipulating the internal `commands'
+\cmd{\input@path} and \cmd{\Ginput@path}, so may behave badly if you
+redefine them manually, or via another package, within the document.
