Custom Summary

Language Definition

This is a formal description of the custom summary language,
used in custom summary and status line template files.

The symbol to the left of the ::= sign is replaced by the
symbols to the right of the ::= sign.

Symbols enclosed in curly brackets {} may be repeated any
number of times, including zero times.

The | character represents a choice between two different
sets of symbols.

The < and > signs enclose a symbolic term.

Anything in boldface is to be included exactly as it appears.
