+Quick and dirty hack to make nice with bitbucket privately hosted repositories that only allow ssh access.  In order to set this up,
+
+    go get github.com/myENA/bbgoget
+
+Alternately you can download the rpm or the tarball from the Releases tab.
+
+As an example configuration, with Apache httpd running on 443 proxying for bitbucket, you could add the following to
+httpd.conf section before the redirects to bitbucket's http service:
+
+            RewriteEngine on
+            RewriteCond "%{QUERY_STRING}" "go-get"
+            RewriteRule "^/(.*)" "http://localhost:8800/$1" [P]
+
+This assumes bbgoget running locally on port 8800.
+
+The integration with bitbucket is minimal / dumb.  It has no knowledge whether or not you actually have a repository 
+at the requested location.  It doesn't really need to, go get will figure out soon enough if the response ends up
+going nowhere.  The up side is this makes configuration easier.  No API access required, minimal configuration.
+As an added benefit of being unconcerned with tight integration with bitbucket, there is a very good chance this
+would work with other git servers.  Also - and most importantly - this made it very easy to author.
+
+
+We've only tested it with our specific configuration.
