+% Remark:
+%
+% This file is a merge of the original punk files by Donald Knuth, who
+% added this comment:
+%
+% Font inspired by Gerard and Marjan Unger's lectures, Feb 1985
+%
+% The regular punk files are part of TeXLive and in metafont format. All
+% errors introduced are ours. We also changed the encoding to unicode. In
+% due time we might add a few more more characters. We still need to
+% improve some of the metrics which involves a bit of trial and error. The
+% font just covers basic latin shapes but in ConTeXt MkIV we add virtual
+% composed shapes. There is a module m-punk.tex that implements this. This
+% derivate is also used in mk.tex (mk.pdf) which is one of our tests for
+% LuaTeX. We published an article on it in the MAPS (NTG magazine).
