The source project of this merge request has been removed.
WIP: Use hashes in all install entities (paths, tarball names, contents of tarballs)
Also simplify long, repeating paths with local variables.
This changes location in the install directory and paths written inside tarballs for tarballs of MC generators. Now everything is in distribution/.
Note that this makes an unconditional change, therefore to be able to merge this, at least a switch, e.g. LCG_USE_HASHES, needs to be added. See SPI-1253 for a discussion.
