 r2env aims to provide a packaging for r2 with support for binary packages and for all major platforms.
 
 r2pm focus on providing more packages, it's written in shellscript, so it doesnt run on windows and requires r2 to work.
 
 Therefor r2env is kind of `nvm` from nodejs or `pyenv` from python. A way to run multiple different versions of r2 in the system.
