## Specifying the version
## 指明版本
You need to specify the package's version some way. When you publish your
package on Packagist, it is able to infer the version from the VCS (git, svn,
hg) information, so in that case you do not have to specify it, and it is
recommended not to. See [tags](#tags) and [branches](#branches) to see how
version numbers are extracted from these.
你需要一些方法来指明自己开发的包的版本,当你在 Packagist 上发布自己的包,它能够从 VCS (git, svn,
hg) 的信息推断出包的版本,因此你不必手动指明版本号,并且也不建议这样做。请查看 [标签](#标签) 和 [分支](#分支) 来了解版本号是如何被提取的。
If you are creating packages by hand and really have to specify it explicitly,
you can just add a `version` field:
如果你想要手动创建并且真的要明确指定它,你只需要添加一个 `version` 字段:
{
"version": "1.0.0"
}

> **注意:** 你应该尽量避免手动设置版本号,因为标签的值必须与标签名相匹配。
### Tags
### 标签
For every tag that looks like a version, a package version of that tag will be
created. It should match 'X.Y.Z' or 'vX.Y.Z', with an optional suffix
of `-patch`, `-alpha`, `-beta` or `-RC`. The suffixes can also be followed by
a number.
对于每一个看起来像版本号的标签,都会相应的创建一个包的版本。它应该符合 'X.Y.Z' 或者 'vX.Y.Z' 的形式,`-patch`、`-alpha`、`-beta` 或 `-RC` 这些后缀是可选的。在后缀之后也可以再跟上一个数字。

### Branches
### 分支
For every branch, a package development version will be created. If the branch
name looks like a version, the version will be `{branchname}-dev`. For example
