# 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.
