Implement go-import filter
The filter acts on http requests with go-get=1 as parameter.
This request is usually issued by go command [1]. The response
contains meta-data indicating the repo location on the server.
More discussion about the feature is available in RFC [2].

+This plugin provides support of
+[remote import paths](https://golang.org/cmd/go/#hdr-Remote_import_paths) and
+[go-get command](https://golang.org/cmd/go/).
+
+### Usage
+
+* Go-get command
+
+```
+go get example.org/foo
+```
+
+* Remote import paths
+
+```
+import "example.org/foo"
+```
+
+### Limitation
+Folder of the repository is not supported in the context of Gerrit up to
+ambiguity of repository name. E.g., _example.org/foo/bar_ has two potential meanings:
+
+* Folder _bar_ in repository _foo_, or
+* repository _foo/bar_.

+Build
+=====
+
+This plugin is built with Buck.
+
+Two build modes are supported: Standalone and in Gerrit tree. Standalone
+build mode is recommended, as this mode doesn't require local Gerrit
+tree to exist.
+
+Build standalone
+----------------
+
+Clone bucklets library:
+
+```
+ git clone https://gerrit.googlesource.com/bucklets
+```
+and link it to @PLUGIN@ directory:
+
+```
+ cd @PLUGIN@ && ln -s ../bucklets .
+```
+
+Add link to the .buckversion file:
+
+```
+ cd @PLUGIN@ && ln -s bucklets/buckversion .buckversion
+```
+
+Add link to the .watchmanconfig file:
+
+```
+ cd @PLUGIN@ && ln -s bucklets/watchmanconfig .watchmanconfig
+```
+
+To build the plugin, issue the following command:
+
+```
+ buck build plugin
+```
+
+The output is created in:
+
+```
+ buck-out/gen/@PLUGIN@.jar
+```
+
+This project can be imported into the Eclipse IDE:
+
+```
+ ./bucklets/tools/eclipse.py
+```
+
+To execute the tests run:
+
+```
+ buck test
+```
+
+To build plugin sources run:
+
+```
+ buck build src
+```
+
+The output is created in:
+
+```
+ buck-out/gen/@PLUGIN@-sources.jar
+```
+
+Build in Gerrit tree
+--------------------
+
+Clone or link this plugin to the plugins directory of Gerrit's source
+tree, and issue the command:
+
+```
+ buck build plugins/@PLUGIN@
+```
+
+The output is created in:
+
+```
+ buck-out/gen/plugins/@PLUGIN@/@PLUGIN@.jar
+```
+
+This project can be imported into the Eclipse IDE:
+
+```
+ ./tools/eclipse/project.py
+```
+
+To execute the tests run:
+
+```
+ buck test --include @PLUGIN@
+```
+
+How to build the Gerrit Plugin API is described in the [Gerrit
+documentation](../../../Documentation/dev-buck.html#_extension_and_plugin_api_jar_files).
