Write `al` in Rust

[gabebw]

The tool should iterate through all files and sort them by their modification time (exactly like ls -t). Maybe that's mtime, maybe not: OS X does things a little differently. I think ls uses mtime.

Compare GetFileInfo file to stat -x file.

• Hardcode to 10 results then add option handling to look at ARGV[0] (no flag, like head 10) for max number of results
• -r/--recursive: Recursively show most recent files across all directories (after adding option handling)
