+# shell-words
+
+Process command line according to parsing rules of Unix shell.
+
+## Usage
+
+Add this to Cargo.toml:
+```toml
+[dependencies]
+shell-words = "1.0.0"
+```
+
+Add this to your crate:
+```rust
+extern crate shell_words;
+```
+
+## Examples
+
+### Split
+
+Compiling C source code into an executable as in default build rule found in GNU Make:
+
+```rust
+extern crate shell_words;
+
+use std::env::var;
+use std::process::Command;
+
+fn main() {
+    let cc = var("CC").unwrap_or_else(|_| "cc".to_owned());
+
+    let cflags = var("CFLAGS").unwrap_or_else(|_| String::new());
+    let cflags = shell_words::split(&cflags).expect("failed to parse CFLAGS");
+
+    let cppflags = var("CPPFLAGS").unwrap_or_else(|_| String::new());
+    let cppflags = shell_words::split(&cppflags).expect("failed to parse CPPFLAGS");
+
+    Command::new(cc)
+        .args(cflags)
+        .args(cppflags)
+        .args(&["-c", "a.c", "-o", "a.out"])
+        .spawn()
+        .expect("failed to start subprocess")
+        .wait()
+        .expect("failed to wait for subprocess");
+}
+```
+
+### Join
+
+Logging executed commands in format that can be readily copied and pasted to a shell:
+
+```rust
+extern crate shell_words;
+
+fn main() {
+    let argv = &["python", "-c", "print('Hello world!')"];
+
+    println!("Executing: {}", shell_words::join(argv));
+
+    std::process::Command::new(&argv[0])
+        .args(&argv[1..])
+        .spawn()
+        .expect("failed to start subprocess")
+        .wait()
+        .expect("failed to wait for subprocess");
+}
+```
