+### 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'.
