- add checkUpdateSyntax and also add json output for update messages
- additionally this commit also includes error Container for consistent outputs
in case of errors, very handy to write scripts around
```bash
$ mc --json ls test | jq .error
null
null
{ error }
null
...
```
- over the course of a project history every maintainer needs to update
its dependency packages, the problem essentially with godep is manipulating
GOPATH - this manipulation leads to static objects created at different locations
which end up conflicting with the overall functionality of golang.
This also leads to broken builds on many platforms. There is no easier way out of
this other than asking users to do 'godep restore' all the time which perhaps as
a practice doesn't sound clean, also has its own set of problems.
- govendor on the other hand is a right tool but a stop gap tool until we wait for
golangs official 1.5 version which fixes this vendoring issue once and for all.
- govendor makes sure that the import paths are re-written instead of manipulating
GOPATH.
This has advantages
- no more compiled objects being referenced in GOPATH and build time GOPATH
manging which leads to conflicts.
- proper import paths referencing the exact package a project is dependent on.
govendor is simple and provides the minimal necessary tooling to achieve this.
For now this is the right solution.
