> % erl -install cowboy

In my humble opinion, such a command is basically a tool who does a few  
things : lookup in a repository index a package named 'cowboy', fetch it,  
compile it in a place and update a file (like $HOME/.erlang) to add it to  
the path. Someone may have said it already in the millions mails of the  
list I couldn't read today, but the main problem would be "Who handles the  
repository index".

I believe there are already such indexes, one for elixir and one called  
agner. Maybe others. IMHO if "the Erlang/OTP group at Ericsson" (as said  
on erlang.org) starts such an official packages index, writing a script   
to fetch the packages will take less than hour, rebar will be updated to  
handle this, and multiple tools will appear in the community. The main  
thing is to find who will be considered as an "official enough" index  

(sorry for bad english ...)
