+% Improvements to this file in v1.2 (unpublished) and v1.3 owe almost

+%
+% v1.4 adds family-specific support for microtype. This draws also on the
+% documentation for the microtype package and MinionPro.sty. MinionPro.sty 
+% is available as part of the minionpro package and can be obtain from
+% http://mirror.ctan.org/fonts/minionpro. MinionPro.sty is in the public

+% from http://ctan.org/pkg/microtype. It is part of the microtype package which
+% is itself licensed under the LPPL.
