# Script to generate a tarball
# We use git to output a tree. But we also want to build the user documentation
# and put that in the tarball, so that nobody needs to have doxygen installed
# to build it.

# git can do that automatically for us via git-archive
# but to get the documentation in, we need to make a symlink called "fish-VERSION"
# and tar from that, so that the documentation gets the right prefix
# We need GNU tar as that supports the --mtime and --transform options
