goup is a simple Go installer.
It is notorious that an operating system's package manager takes a long time to update Go to the latest version, particularly on Linux distros.
goup makes Go installation and version management easier.
Besides, goup does not inject junks into your shell, like other version managers.
goup is heavily inspired by golang/dl and getgo.
goup initoutputs a file ($HOME/.go/env) that exports goup's ($HOME/.go/bin) and Go's ($HOME/.go/current/bin) bin directory in yoru PATH environment variable.goup updatedownloads specified version of Go and symlinks downloaded version to$HOME/.go/current.goup showshows the current installed Go version.
