Using pip is the preferred method of installation, as it installs cdl_convert both as a python module and a script.
$ pip install cdl_convert
If you don’t want to bother with a pip style install, you can alternatively grab cdl_convert/cdl_convert.py, as this file is the script and all the functions and classes needed.
You will need to place the python file somewhere (such as a bin folder), and either run the script by directly invoking the file directly or creating an alias to the file location.
Creating aliases, etc are beyond the scope of this documentation.
