A clone of grep, very lightweight.
This is part of my journey of learning Rust, trying to get the basics right. I'm also following a very good book, Rust in Action, which elaborates on advanced concepts and things about the language.
Usage: grep-lite [OPTIONS] --pattern <PATTERN>
Options:
-e, --pattern <PATTERN>
-i, --input <INPUT>
-b, --before <BEFORE>
-a, --after <AFTER>
-h, --help Print help
-V, --version Print version
