The archive files hosted here contain the Pharo Launcher files. These files are automatically created and uploaded by this Jenkins Job: https://ci.inria.fr/pharo/view/all/job/Launcher/ The scripts executed by this job are hosted at: https://github.com/pharo-project/pharo-ci/tree/master/ci-jobs/pharo/ The files in the blessed/ subdirectory are just copied there from the current directory using this script: https://github.com/pharo-project/pharo-ci/blob/master/bless.sh The idea of the blessed/ subdirectory is that a file content under a given filename will never change. This is required by some GNU/Linux distributions and processes. On the contrary, the files in the current directory are automatically generated by the Jenkins job which frequently erases files.
