+
+Same idea as (but implementation not directly based on) the Python shlex
+module. However, this implementation does not support any of the Python
+module's customization because it makes parsing slower and is fairly useless.
+You only get the default settings of shlex.split, which mimic the POSIX shell:
+<https://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html>
+
+This implementation also deviates from the Python version in not treating \r
+specially, which I believe is more compliant.
+
+This crate can be used on either normal Rust strings, or on byte strings with
+the `bytes` module. The algorithms used are oblivious to UTF-8 high bytes, so
+internally they all work on bytes directly as a micro-optimization.
+
+Disabling the `std` feature (which is enabled by default) will allow the crate
+to work in `no_std` environments, where the `alloc` crate, and a global
+allocator, are available.
