Python interface for reading and appending tar files, while keeping a fast index for finding and reading files in the archive.

This interface has been successfully used to store and manage over one billion files in one of the Pilot-2 simulation campaigns.

Written by Tomas Oppelstrup as part of the DOE/NCI Pilot-2 project, based on an initial (simpler) index implementation by Tomas Oppelstrup, December 11, 2018. Updated to support Python 3 as a module by Francesco DiNatale.

A script for correctness checking and examples of use can be found in tests/indextest.py. The simplest way to run the tests is by e.g.: cd test ./testscript.sh
