+# Remove C and C++ comments, by Brian Hiles (brian_hiles@rocketmail.com)
+
+# Sped up (and bugfixed to some extent) by Paolo Bonzini (bonzini@gnu.org)
+# Works its way through the line, copying to hold space the text up to the
+# first special character (/, ", ').  The original version went exactly a
+# character at a time, hence the greater speed of this one.  But the concept
+# and especially the trick of building the line in hold space are entirely
+# merit of Brian.
