 1 | # check-code-google-com
 2 | 
 3 | Check your package is depend on code.google.com
 4 | 
 5 | March 12, 2015, Google decide to close Google Code.
 6 |

 8 | 
 9 | I am grateful to Google Code. When there was not GitHub, I put my codes on
10 | Google Code. It was very stable. I had never see the server is down.
11 | Unfortunately, Google Code will close. However we, gopher has many codes that
12 | contains packages which is on code.google.com. We must finish transition to
13 | find  alternative packages until the Google Code will close.
14 | 
15 | ## Usage
16 | 
17 | ```
18 | $ check-code-google-com [package]
19 | ```
20 | 
21 | For example:
22 | 
23 | ![Bad](http://go-gyazo.appspot.com/d7648e8179e45bf8.png)
24 | 
25 | ![Good](http://go-gyazo.appspot.com/7f26fede3724d46a.png)
26 | 
27 | Then, which packages are depend on `code.google.com`? So use `-v`
28 | 
29 | ![-v](http://go-gyazo.appspot.com/70269f8014c1ca78.png)
30 | 
31 | ## Installation
32 | 
33 | ```
34 | $ go get github.com/mattn/check-code-google-com
