[GAP Forum] Multi-user Installation on Linux

[Gordon Royle]

Thanks for your reply, and Bill’s addendum.

The only problem with that set up that I can foresee is that one of the users is a package developer and constantly wants to tinker with, update and then re-load the latest version of the package. 

Is there a mechanism that allows each individual to have local versions of the packages but a common core? 

Or do we just go for most users having the common version and those with additional needs running a completely separate installation?
