## Library Usage ## Library Usage
`Pantograph/Library.lean` exposes a series of interfaces which allow FFI call `Pantograph/Library.lean` exposes a series of interfaces which allow FFI call
with `Pantograph`. with `Pantograph` which mirrors the REPL commands above. It is recommended to
call Pantograph via this FFI since it provides a tremendous speed up.

## Nix based workflow ## Nix based workflow
The included Nix flake provides build targets for `sharedLib` and `executable`.
The executable can be used as-is, but linking against the shared library
requires the presence of `lean-all`.
