PyQt-builder is a tool for generating Python bindings for C++ libraries that use the Qt application framework. The bindings are built on top of the PyQt bindings for Qt. PyQt-builder is used to build PyQt itself.
PyQt-builder also includes the :program:`pyqt-bundle` command line tool used to bundle a copy of Qt with a PyQt wheel. This is separate from the build system and described in :ref:`ref-pyqt-bundle`.
PyQt-builder is actually an extension of the PEP 517-compliant SIP bindings generator and build system. In the simplest cases all that is needed is a :file:`pyproject.toml` file that specifies how the bindings are to be generated. More complicated cases require additional code, typically implemented in a :file:`project.py` file.
SIP provides a number of task-orientated command line tools and a :py:mod:`sipbuild` module which can be used to extend the build system. The command line tools include :program:`sip-install` to build and install a set of bindings, and :program:`sip-wheel` to create a wheel that can be uploaded to PyPI.
PyQt-builder doesn't provide any additional command line build tools but does extend the SIP tools by providing additional command line options and options that can be specified in the :file:`pyproject.toml` file. These are implemented by the :py:mod:`pyqtbuild` module which also provides an API that can be used by a project's :file:`project.py` file.
