+# 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", "go1", "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.
+
+Installing
+==========
+
+To install:
+
+    bash < <(curl -s https://raw.github.com/moovweb/gvm/master/binscripts/gvm-installer)
+
+Installing Go
+=============
+    gvm install go1
+    gvm use go1 [--default]
+Once this is done Go will be in the path and ready to use. $GOROOT and $GOPATH are set automatically.
+
+You are now ready to create and use packages built using gpkg. Instructions can be found at http://github.com/moovweb/gpkg
+
+List Go Versions
+================
+To list all installed Go versions (The current version is prefixed with "=>"):
+
+    gvm list
+
+Uninstalling
+============
+To completely remove gvm and all installed Go versions and packages:
+
+    gvm implode
+
+If that doesn't work see the troubleshooting steps at the bottom of this page.
+
+Mac OS X Requirements
+====================
+    Install mercurial from http://mercurial.berkwood.com/
+
+Linux Requirements
+==================
+    sudo apt-get install curl
+    sudo apt-get install git
+    sudo apt-get install mercurial
+    sudo apt-get install make
+    sudo apt-get install binutils
+    sudo apt-get install bison
+    sudo apt-get install gcc
+
+FreeBSD Requirements
+====================
+
+    sudo pkg_add -r bash
+    sudo pkg_add -r git
+    sudo pkg_add -r mercurial
+
+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!
