lektor.build_programs.BuildProgram

A build program is responsible for converting a Source Object into final build artifacts. Typically such a build program implements two methods: produce_artifacts and build_artifact.

The former should invoke declare_artifact for each artifact that should be created from the source. The builder will then invoke build_artifact for each of these declared artifacts if the builder determines that the artifact needs to be built.

For an example refer to the add_build_program documentation.
