elido 1.0.0

Elido fixes an xargs annoyance that's bugged me for long: I frequently had to

handling input lines containing spaces (e.g., filenames).

The basic philosophy of Elido is that we create a command-line then execute it directly: WE DON’T USE THE SHELL TO EXECUTE THE COMMAND LINE. I think this is cleaner since it saves from having to think about multiple levels quoting.
