When I originally looked at the "exclude" option, I thought it meant that it excluded pages completely, but it apparently doesn't. What I've found in practice is that a file which matches the "exclude" regex is excluded from processing, but it is still copied over to the destination directory. Thus, for example, if I have "^Makefile$" as the exclude pattern, and I have a file
src/foo/Makefile, then that file is copied unaltered into
dest/foo/Makefile. However, what I want is for
src/foo/Makefile to be completely ignored: that it is not only not processed, but not even copied into the destination directory.
I'm not sure if the current behaviour is a bug or a feature, but I would like a "totally ignore this file" feature if it's possible to have one.
