Skimming pkg.julialang.org is pleasantly impossible with 904 registered packages. This smells exponential growth.
Is there a tool to simply download the text files in all of the packages? Last time I checked, I wasn't able to do that with github commands. I think it would be impossible to foresee which information might be relevant while keeping the tool you're requesting fast and lightweight. The text files already contain all the info, and we can easily extract data like dependencies from them. So I inelegantly maintain a ghost folder structure with text files from packages I've tried out so far.
