The goal of this project is to make a Cabrillo file parser that can read Cabrillo files that meet the official specification and the common variants that people submit to contests. The Cabrillo file format is somewhat challenging to automatically parse because it is a column-oriented file format. Many lines can be treated like a comma separate value (CSV) file format where the "comma" is whitespace. However, this approach does not work when fields are left empty.

This web article on a technique to discover where the column breaks are in the a plain text file serves as the insipiration for the approach here.

The Cabrillo file format is the de facto computer standard for logging ham radio contests.
