Source for the 5-character hash in $HOME/.julia/packages/<pkgname>/

Hello all,

I notice that each package in my $HOME/.julia/packages/<pkgname>/ folder has what looks like a 5-character hash code - for example, $HOME/.julia/packages/HTTP/aTjcj. Can anyone tell me how this hash is derived, or where it can be read from?


It’s derived from the package UUID and the tree hash as recorded in the manifest.
