Installation

To install this package, follow the standard procedure for installing Python modules. The package may be installed either systemwide, in the default location, or for a single user, by changing the install location and updating environment variables in the standard way, as indicated by the Python documentation [1].

Note that for the default install you may need administrative privileges on the machine you are using. Consult the Python documentation for the single-user install procedure.

The install script will install the Python package in the default place for your platform. Additionally, it will install example scripts in a subdirectory flowtracks-examples/ under the default executable location, and a the documentation in the default package root. For information on where these directories are on your platform (and how to change them), refer to the Python documentation [1]. Other standard features of the setup script are also described therein.

The examples are Jupyter notebooks [2], and can be previewed without any special setup under the examples section of
