Release v0.020

This release adds the first initial development of ygrok, the Yertl program for parsing lines of plain text input into documents.

ygrok is perfect for parsing log files and command output. By using simple patterns or named regex captures, we can parse a line of input into a document, which we can then write to a database using ysql, or convert to CSV or JSON with yto.

Lots more development on ygrok to come!
