# Use vendored crate dependencies so we can build offline.
# Created using https://github.com/alexcrichton/cargo-vendor/ 0.1.7
# It's so big because some of the -sys crates include the C library source they
# want to link to.  With our -devel buildreqs in place, they'll be used instead.
# FIXME: These should all eventually be packaged on their own!

%description
Cargo is a tool that allows Rust projects to declare their various
dependencies and ensure that you'll always get a repeatable build.
