Motivation

One of the core benefits of tea: it's relocatable. tea does not pollute your system environment, everything gets "installed" in a relocatable folder ~/.tea.

tea can also install languages like node and ruby and it's dependency managers, npm and gem, respectively. However, these language dependency managers install packages to global directories like ~/.npm and ~/.gem. Tools from these ecosystems expect to find packages in these locations.

In this RFC, we would love to hear feedback from the community.
