If the developer is missing any dependencies, for instance `github.com/spf13/cobra/cobra`, `go install` will fail:
```bash
../../spf13/viper/util.go:29:2: cannot find package "gopkg.in/yaml.v2" in any of:
/Users/campoy/src/golang.org/x/go/src/gopkg.in/yaml.v2 (from $GOROOT)
/Users/campoy/src/gopkg.in/yaml.v2 (from $GOPATH)
```
While `go get github.com/spf13/cobra/cobra` will build the tool successfully.
Docker (https://github.com/docker/docker) now
also uses Cobra for the CLI. A majority of the
commands have been migrated (still some left),
but adding it already :)

* Refactoring code that unnecessarily declares a map before making it.
* Cleaning up gpl3 formatting to match other licenses.
* Adding functionality that allows specifying custom license header
and text in cobra config.
* Using license header and text as templates so that they can use
template variables (for custom and gpl3 licenses).
* Adding ability to specify no license.
* Adding custom license example to README.
An example from the kubernetes project, for the `kubectl config`
command, which as subcommands, and flags, and all sorts of stuff, it
will generate markdown like so:
config modifies .kubeconfig files
config modifies .kubeconfig files using subcommands like "kubectl config set current-context my-context"
```
kubectl config SUBCOMMAND
```
```
--envvar=false: use the .kubeconfig from $KUBECONFIG
--global=false: use the .kubeconfig from /home/username
-h, --help=false: help for config
--kubeconfig="": use a particular .kubeconfig file
--local=false: use the .kubeconfig in the current directory
```
```
--alsologtostderr=false: log to standard error as well as files
--api-version="": The API version to use when talking to the server
-a, --auth-path="": Path to the auth info file. If missing, prompt the user. Only used if using https.
--certificate-authority="": Path to a cert. file for the certificate authority.
--client-certificate="": Path to a client key file for TLS.
--client-key="": Path to a client key file for TLS.
--cluster="": The name of the kubeconfig cluster to use
--context="": The name of the kubeconfig context to use
--insecure-skip-tls-verify=false: If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure.
--log_backtrace_at=:0: when logging hits line file:N, emit a stack trace
--log_dir=: If non-empty, write log files in this directory
--log_flush_frequency=5s: Maximum number of seconds between log flushes
--logtostderr=true: log to standard error instead of files
--match-server-version=false: Require server version to match client version
--namespace="": If present, the namespace scope for this CLI request.
--password="": Password for basic authentication to the API server.
-s, --server="": The address and port of the Kubernetes API server
--stderrthreshold=2: logs at or above this threshold go to stderr
--token="": Bearer token for authentication to the API server.
--user="": The name of the kubeconfig user to use
--username="": Username for basic authentication to the API server.
--v=0: log level for V logs
--validate=false: If true, use a schema to validate the input before sending it
--vmodule=: comma-separated list of pattern=N settings for file-filtered logging
