+### SYNOPSIS
+###
+###   mdw_DIR_TEXMF
+###
+### DESCRIPTION
+###
+###   Define the substitution `@texmfdir@' to name a sensible TeX
+###   installation root directory.
+###
+###   A `--with-texmfdir' command-line option is defined, which allows the
+###   end user to select a specific installation root.  The default is chosen
+###   according to a heuristic, which is currently to use the first of
+###
+###     * `DATADIR/texmf',
+###     * `PREFIX/lib/texmf',
+###     * `PREFIX/texmf',
+###     * `LIBDIR/lib/texmf'.
