-# 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");
-}
-```

-/// Splits command line into separate arguments, in much the same way Unix shell
-/// would, but without many of expansion the shell would perform.
-///
-/// The split functionality is compatible with behaviour of Unix shell, but with
-/// word expansions limited to quote removal, and without special token
-/// recognition rules for operators.
-///
-/// The result is exactly the same as one obtained from Unix shell as long as
-/// those unsupported features are not present in input: no operators, no
-/// variable assignments, no tilde expansion, no parameter expansion, no command
-/// substitution, no arithmetic expansion, no pathname expansion.
-///
-/// In case those unsupported shell features are present, the syntax that
-/// introduce them is interpreted literally.
-///
-/// # Errors
-///
-/// When input contains unmatched quote, an error is returned.
-///
-/// # Compatibility with other implementations
-///
-/// It should be fully compatible with g_shell_parse_argv from GLib, except that
-/// in GLib it is an error not to have any words after tokenization.
-///
-/// It is also very close to shlex.split available in Python standard library,
-/// when used in POSIX mode with support for comments. Though, shlex
-/// implementation diverges from POSIX, and from implementation contained herein
-/// in three aspects. First, it doesn't support line continuations.
-/// Second, inside double quotes, the backslash characters retains its special
-/// meaning as an escape character only when followed by \\ or \", whereas POSIX
-/// specifies that it should retain its special meaning when followed by: $, \`,
-/// \", \\, or a newline. Third, it treats carriage return as one of delimiters.
-///
-/// # Examples
-///
-/// Building an executable using compiler obtained from CC environment variable
-/// and compiler flags from both CFLAGS and CPPFLAGS. Similar to default build
-/// rule for C used in GNU Make:
-///
-/// ```rust,no_run
-/// use std::env::var;
-/// use std::process::Command;
-///
-/// let cc = var("CC").unwrap_or_else(|_| "cc".to_owned());
