### Nix wrapper
On NixOS or when using `nix`, `clang-uml` provides a wrapper script called
`clang-uml-wrapped`, which builds and exports `CPATH` and `CPLUS_INCLUDE_PATH`
On NixOS or when using `nix`, `clang-uml` uses a wrapper script,
which builds and exports `CPATH` and `CPLUS_INCLUDE_PATH`
environment variables before running `clang-uml`, which contain valid
system header Clang paths for the current Nix environment.
The `clang-uml-wrapped` script can be called the same way as `clang-uml` and
should resolve the system include paths without the need for any of the above
solutions.
If you want to use an unwrapped version, the `clang-uml-unwrapped` binary
can be called the same way as `clang-uml`.
