"""
Redirect calls to open, etc. to a virtual file system.

Use this to mount a zip file as a file system, and then all subsequent calls
to chdir, open, etc. will reference files in the zip file instead of the disk.

This will only work for packages which do all their I/O in python, and not
those which use direct calls to the C library, so for example, it will not
work with h5py. XML parsing from a zip file is also unlikely to work since
expat uses the C library directly for parsing.

# venv -n[3.x] name [packages...]
#    Creates an environment using python 3.x (default 3.8).
