The trace text format produced and consumed by this package is a line-oriented
format.

The first line in each text trace is the header line.

	Trace Go1.XX

Following that is a series of event lines. Each event begins with an
event name, followed by zero or more named unsigned integer arguments.
Names are separated from their integer values by an '=' sign. Names can
consist of any UTF-8 character except '='.

For example:

//   - diff nicely in git history and code reviews.
//
// Non-goals include being a completely general archive format,
// storing binary data, storing file modes, storing special files like
// symbolic links, and so on.
//
// # Txtar format
//
// A txtar archive is zero or more comment lines and then a sequence of file entries.
// Each file entry begins with a file marker line of the form "-- FILENAME --"

// license that can be found in the LICENSE file.
