Yes, I think we should do that, and make some sort of release,
possibly squashing all the changes... my current branch counts 218
commits.

It looks like my tag file was tabs instead of spaces, so that line
makes everything explode... how about:
awk "\$4 ~ /[$1]/ { print \$1 }" $TMPFILE | sort | uniq

Maybe:
awk "\$1 ~ /^$1/ { print \$2 }" $TMPFILE | sort | uniq

There's no $low, I guess you meant $new.

Did you mean $token?

This is simpler:
dos2unix -n $file $TMPFILE1
However, I think dos2unix should be run separately.

This is simpler:
sed -e "s/\<$token\>/$new/g" $TMPFILE1 > $file

No need to say that.

I did a few more cleanups (yeah, I'm too picky) and here's the result.
Unfortunately I still think it needs some work in the camel conversion
(E_FOO, __FOOBAR__, etc.)
