+You can specify a special kind of font path in the form \fBcatalogue:<dir>\fR.
+The directory specified after the catalogue: prefix will be scanned for symlinks
+and each symlink destination will be added as a local fontfile FPE.
+The symlink can be suffixed by attributes, such as '\fBunscaled\fR', which
+will be passed through to the underlying fontfile FPE.  Except the new
+attribute '\fBpri\fR' which will be used for ordering the fontfile FPEs.
+
+An example configuration:
+
+.nf
+    75dpi:unscaled:pri=20 \-> /usr/share/X11/fonts/75dpi
+    ghostscript:pri=60 \-> /usr/share/fonts/default/ghostscript
+    misc:unscaled:pri=10 \-> /usr/share/X11/fonts/misc
+    type1:pri=40 \-> /usr/share/X11/fonts/Type1
+    type1:pri=50 \-> /usr/share/fonts/default/Type1
+.fi
+
+will add /usr/share/X11/fonts/misc as the first FPE with the attribute
+'unscaled', second FPE will be /usr/share/X11/fonts/75dpi, also with
+the attribute unscaled etc.  This is functionally equivalent to setting
+the following font path:
+
+.nf
+    /usr/share/X11/fonts/misc:unscaled,
+    /usr/share/X11/fonts/75dpi:unscaled,
+    /usr/share/X11/fonts/Type1,
+    /usr/share/fonts/default/Type1,
