update-golang

update-golang is a script to easily fetch and install new Golang releases with minimum system intrusion. The script uses local system OS and ARCH to download the correct binary release. It is not harmful to run the script multiple times. Downloaded releases are kept as cache under '/usr/local'. You can erase them manually. By default, the script only detects actual releases (not beta releases, not release candidates). However one can force any specific non-final release. The default behavior is to install Golang globally for all system users. However, you can use the environment variables to point locations to your per-user home directory. The per-user installation does not need root (sudo) privileges. You can use the '-declutter' option to prevent caching downloaded archives.
