+stands for \"Almost European\".  The main use of the package was to produce
+PDF files using Adobe Type 1 versions of the CM fonts instead of bitmapped EC
+fonts.  Note that direct substitutes for the bitmapped EC fonts are available,
+via the CM-super, Latin Modern and (in a restricted way) CM-LGC font sets.")
