# How to use this package?
#
# First-time setup: this nixpkg downloads the conda installer and provides a FHS
# env in which it can run. On first use, the user will need to install conda to
# the installPath using the installer:
# $ nix-env -iA conda
# $ conda-shell
# $ conda-install
#
# Under normal usage, simply call `conda-shell` to activate the FHS env,
# and then use conda commands as normal:
# $ conda-shell
# $ conda install spyder

# on line 10, we have 'unset LD_LIBRARY_PATH'

# The reason is that the binary payload is encoded as number
# of bytes from the top of the installer script
# and unsetting the library path prevents the zlib library from being discovered
