For example such packages are `DUI`, `fast_dp`, `iota`, `screen19`. * this makes all normal python dispatchers able to import dials/dxtbx/xia2/., which is relevant for all external packages that make use of DIALS and enables them to be absolute standard Python packages with zero required additional dark magic. * this means we no longer need to generate a `pytest` dispatcher Making `import` work with standard `conda/bin/python` - no `libtbx.python` dispatcher required. The intention is to create a `setup.py` file for DIALS in the `modules/dials/` directory that is generated, installed, and `develop`'d through `dials/libtbx_refresh.py`ġ. * Make bootstrap print out '*you're in uncharted territory*' if you change the Python version on a release build that has otherwise pinned conda-forge packages. * With this we can remove all C++ source code and intermediate files We can provide manual instructions for converting. * Not reasonable to provide an 'upgrade' path, as that would need to rebuild everything anyway. **WP4**: The installer should only install user installation, not development installation * This would allow us to remove C compilers, alabaster, sphinx, scons, pytest. `linux.txt` into run/dev, and then there will be some overlap between platforms and it can probably be simplified **WP3**: have a run-time spec and a development environment

* takes all the above files and does the base & build stepģ. * Add an `-offline` option to bootstrap that * tells miniconda to resolve and download the environment (not: install) * Add a `-download` option to bootstrap that Currently this is covered by downloading a release.

**WP2:** Support an offline developer installation. * Also: disconnect the DIALS installer scripts from libtbxĢ. * do the remainder of the DIALS installer bit * run the `conda-pack` post install fixer-upper * do the equivalent of the create-installer script using the `conda-pack`'d environment

* use `conda-pack` to pack up the correct environment * The installer should be able to run offline. * Having this would mean that we have a valid (non-relocated) conda environment in the installation, which would resolve eg. * This does not depend on anything else really, so we can start here.

**WP1:** We can use () to pack up the environment.
