<commit_before>**Miller is like sed, awk, cut, join, and sort for name-indexed data such as CSV.**

With Miller, you get to use named fields without needing to count positional
indices.

For example:

```
% mlr --csv cut -f hostname,uptime mydata.csv
% mlr --csv sort -f hostname,uptime mydata.csv
% mlr --csv put '$z = $x + 2.7*$y' mydata.csv
% mlr --csv filter '$status != "down"' mydata.csv<commit_msg>Add Travis Build Status Image to Readme<commit_after>**Miller is like sed, awk, cut, join, and sort for name-indexed data such as CSV.**
