Version 1.2 has been released! Along with minor tweaks, this includes the ATLAS-SUSY-2017-04 displaced vertices analyses written with Manuel Utsch that were included in MadAnalysis in arXiv:2112.05163, also with Jack Araz and Benjamin Fuks.
There is also a script that you can download to install all the relevant tools and set up your HackAnalysis makefile with the correct paths.
The release is timed to be in line for the upcoming release of BSMArt which features HackAnalysis integration.
