## Installation

Use the upstream install or setup path that matches your environment:
- $ brew install xsv
- cargo install xsv
- git clone git://github.com/BurntSushi/xsv
- cargo build --release

Basic usage or getting-started notes:
- **search** - Run a regex over CSV data. Applies the regex to each field
- So, this command takes about 12 seconds to run on my machine, but we can speed
- be parsed. For example, let's say you wanted to grab the last 10 records:
