I usually build OTP from sources running `./configure --prefix=/opt/otp-r15b02` makes it installed into the named location.

I also put something like the following into my ~/.bashrc or ~/.profile:


function use-15b01() {
export PATH="/opt/otp-r15b01/bin:${PATH_NO_OTP}"

function use-15b02() {
export PATH="/opt/otp-r15b02/bin:${PATH_NO_OTP}"

And switch the version of OTP to use executing one of the declared functions.

And how do I go about doing that? or Should I create new folder for each version in order to switch amongst them because we have systems that are written with different versions of Erlang.
