1. What Regular Expressions do

These tutorials are intended as a guide for people who wrangle metadata.

More specifically, they're aimed at people who wrangle tab-separated metadata and have noticed that excel has it's limits.

The name 'regular expressions' (or 'regex') isn't particularly intuitive, and at first sight, regular expressions themselves look a lot like goobledegook.

They do make sense though, and with a little practice, can be very, very powerful.
