-#### Limitations 
-
-There are know limitations on old go version due to the radix/v3 dependency, given that on old versions, 
-the go command in GOPATH mode does not distinguish between major versions, meaning that it will look for the package `package github.com/mediocregopher/radix/v3` instead of v3 of `package github.com/mediocregopher/radix`.
-Therefore you should only use this tool on go >= 1.11.
