# since curl-sys is somehow totally broken, we need to work around it
#
# the problem is basically that at least with curl-sys 0.4.35, the static-curl
# option will make the build.rs copy curl source files from inside curl/ in the
# source tree, but the directory is empty; there is logic in the build.rs that
# checks for existence of '.git' inside curl/, and if it doesn't exist, it
# runs 'git submodule update', which is supposed to clone a copy of curl into
# the source tree from git, but a curl-sys release tarball is not a git repo
# and does not contain .git or .gitmodules at all, so that just fails anyway
#
# so work around the whole mess by fetching our own curl-sys, our own copy of
# curl itself, then arrange things appropriately, create the .git inside curl/
# to fool build.rs into not trying to run git, and then patch Cargo.toml inside
# cargo to use our patched tree...
