#! /bin/sed -nf
# 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.
# Taken from http://sed.sourceforge.net/grabbag/scripts/remccoms3.sed
# According to http://sed.sourceforge.net/grabbag/ it's in the public domain
# Changes:
# 2010-11-06: Remove strings

# This line is sufficient to remove C++ comments!
