1//! Handing a command to the shell implementation.
2//!
3//! The port is not finished, and a half-ported tool that refuses the commands
4//! it has not reached yet is worse than no port at all. So the shell version
5//! is carried in the binary as well, and anything not yet in Rust runs through
6//! it. Commands move across one at a time, and nobody has to care which is
7//! which.
8//!
9//! It needs bash and python3 on the machine. Once a command is ported, its
10//! entry disappears from here, and when the list is empty the shell copy and
11//! this module go with it.
