It recognize both short and long flags. Version number is
automatically added from the latest tag in your git repository.

```shell
go get code.foilhatguy.casa/pub/version
```
2. Add the package as a tool dependency to your project in
tools.go:
```go
// +build tools

package tools

import (
	_ "code.foilhatguy.casa/pub/version"
)
```
3. In the main package add a go:generate directive:
```go
//go:generate go run code.foilhatguy.casa/pub/version
```
4. Run code generator by **go generate** command:

tag from your project. Then it will generate a **version.go**

number as a constant and code for --version flag detection.

```shell
go run . --version
```
