# Clerk The build system for Catala built on top of [ninja](https://ninja-build.org/). ## Usage Use `clerk --help` if you have installed it to get more information about the command line options available. To get the development version of the help, run `make help_clerk` after `make build`. The `clerk` binary corresponds to the Catala build system, responsible for testing among other things. ## Under the hood To perform tests, Clerk will first generate a `build.ninja` file with required rules and build statements retrieved from the given input path(s), before executing the command `ninja test`. The handling of the `ninja` structure is done with the module `Ninja_utils`.
