### How to use the installation script
### ===================================
#
# To install this package, you need conda installed (the conda command must work
# in your shell, see https://docs.conda.io/en/latest/miniconda.html),
# then install the package like:
#
#   $ bash install.sh -d --python 3.6 --name *env_name*
#
# To get information on the flags, run
#
#   $ bash install.sh --help"
