+a tiny AWK script for converting EPS files into Metafont; @code{mftoeps} for
+generating (encapsulated) PostScript files readable, e.g., by CorelDRAW, Adobe
+Illustrator and Fontographer; a collection of routines (in folder progs) for
+converting Metafont-coded graphics into encapsulated PostScript; and
+@code{roex.mf}, which provides Metafont macros for removing overlaps and
+expanding strokes.  In @code{mftoeps}, Metafont writes PostScript code to
+a log-file, from which it may be extracted by either TeX or AWK.")
