So I downloaded the first Pharo Core 1.4: https://gforge.inria.fr/frs/download.php/28660/PharoCore-1.4-14000.zip but, I still do not know what packages to load. Is there an easy way to figure these ones out (and in particular the loading order)? > Exp2: > The second step is to see if it makes sense to manage Core Image with > Metacello or if in addition to the list of packages > we can load the tools manage with metacello (notice that it would mean > also the packages that we will move out of current core): > How much times does it take to load the packages and projects of tools > that would be in Pharo (not Core) and check the time to do it. > We can measure that from a version of core that we consider as > a potential seed and/or > with a version that would get some stuff loaded (and would > correspond to the latest build). Exactly. If you tell me from which image to start and the list of packages I will try to go through this experience. But, I need help because I am an outsider when it comes to this problem.
