Replication package for technical lag analysis for the JSEP journal.

This is the replication package for our article "A Formal Framework for Measuring Technical Lag in Component Repositories --- and its Application to npm" submitted for the JSEP journal in 2018.

This replication package requires Python 3.5+ to be installed, and all the dependencies listed in ``requirements.txt``.
They can be automatically installed using ``pip install -r requirements.txt``. 
These experiment were executed on a Linux Ubuntu OS.

To obtain the analysis used in the paper, one should execute ``jupyter notebook`` at the root of this replication package, and open the notebook contained in ``notebooks``.

This replication package contains three folders (i.e scripts, notebooks and data), each folder has a README with a description of what it contains.

The list of all npm package releases and Github repositories with their dependencies was download from the last available dataset of libraries.io: https://zenodo.org/record/1196312
