## Installation of rust-bindgen

Install rust-bindgen by running the following commands:

    cargo build --release

To test the results, issue: cargo test --release. Four tests, `header_issue_544_stylo_creduce_2_hpp`, `header_constified_enum_module_overflow_hpp`, `header_typedef_pointer_overlap_h`, and `header_nsbasehashtable_hpp`, are known to fail.

Now, as the `root` user:

    install -v -m755 target/release/bindgen /usr/bin

Still as the `root` user, install the Bash and Zsh completion support files:

    bindgen --generate-shell-completions bash \
        > /usr/share/bash-completion/completions/bindgen
    bindgen --generate-shell-completions zsh  \
        > /usr/share/zsh/site-functions/_bindgen
