X-Git-Tag: nailing-cargo/1.0.0~188
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=30396fe34392dfd150bd9bd9814394e01baf0e22;p=nailing-cargo.git

nailing-cargo: Provide a dummy build.rs

Without this, cargo might do this:

    package `<crate> <version> (/home/....)` specifies that it links
    to `<some library>` but does not have a custom build script

When generating a lockfile it doesn't actually need to look at the
build.rs so an empty one will do fine to placate it.
