+# gvm
+by Josh Bussdieker (jbuss, jaja, jbussdieker)
+
+GVM provides an interface to manage Go versions.
+
+Features
+========
+* Install/Uninstall Go versions with `gvm install [tag]` where tag is "60.3", "weekly.2011-11-08", or "tip"
+* List added/removed files in GOROOT with `gvm diff`
+* Manage GOPATHs with `gvm pkgset [create/use/delete] [name]`
+* List latest release tags with `gvm listall`. Use `--all` to list weekly as well.
+* Cache a clean copy of the latest Go source for multiple version installs.
+
+Background
+==========
+When we started developing in Go mismatched dependencies and API changes plauged our build process and made it extremely difficult to merge with other peoples changes.
+
+After nuking my entire GOROOT several times and rebuilding I decided to come up with a tool to oversee the process. It eventually evolved into what gvm is today.

+Troubleshooting
+===============
+Sometimes especially during upgrades the state of gvm's files can get mixed up. This is mostly true for upgrade from older version than 0.0.8. Changes are slowing down and a LTR is imminent. But for now `rm -rf ~/.gvm` will always remove gvm. Stay tuned!
