-in this argument can not find such files unless they are in the

-the command so that it will find any files that \LaTeX\ can find.
-For example on newer web2c \TeX\ releases on unix, one may modify the
-above command so that the last argument is:\\
-|{`zcat `kpsewhich -n latex tex #1`}|\\
-which incantation causes the |kpsewhich| program to find the
-file, by searching along \LaTeX's path, and then pass the full path
-name to the |zcat| program so that it can uncompress the file.
-Any such uses are very system dependent, and would best be placed in
