@fiore @hipsterelectron @Lightfighter @TodePond It's "simple" in terms of what it does - the package managment is just some shell scripts, the packages are just a tarball with an appropriate file hierarchy. Running 'installpkg' unpacks the tarball, copies everything to where it's supposed to go (binary to /usr/ config to /etc/, and so on), can do some things like validating a checksum and such, but, it's very basic.
So, simple in execution, but, assumes the admin knows what they are doing.
