+[![Build Status](https://travis-ci.org/mattn/go-shellwords.svg?branch=master)](https://travis-ci.org/mattn/go-shellwords)
+
+Parse line as shell words.
+
+## Usage
+
+```go
+args, err := shellwords.Parse("./foo --bar=baz")
+// args should be ["./foo", "--bar=baz"]
+```
+
+```go
+os.Setenv("FOO", "bar")
+p := shellwords.NewParser()
+p.ParseEnv = true
+args, err := p.Parse("./foo $FOO")
+// args should be ["./foo", "bar"]
+```
+
+```go
+p := shellwords.NewParser()
+p.ParseBacktick = true
+args, err := p.Parse("./foo `echo $SHELL`")
+// args should be ["./foo", "/bin/bash"]
+```
+
+```go
+shellwords.ParseBacktick = true
+p := shellwords.NewParser()
+args, err := p.Parse("./foo `echo $SHELL`")
+// args should be ["./foo", "/bin/bash"]
+```
