# Build the Jupyter lite web app, the pyodide kernel option is passed for offline availability
# (see https://jupyterlite.readthedocs.io/en/latest/howto/configure/advanced/offline.html), the
# Kernel version is taken from https://github.com/jupyterlite/pyodide-kernel/blob/main/packages/pyodide-kernel/package.json
# 
# We need to trim the size of our package down, so we are explicitly deleting some default wheels
# from the resulting output.  Hacky!
