18 file uses an INI-style format. Stanzas, or top-level sections, are
19 delimited by square braces: [ ]. Within each section, each line
20 defines a relation, which assigns tags to values, or to a subsection,
21 which contains further relations or subsections.
22 .\" Tags can be assigned multiple values
23 An example of the INI-style format used by this configuration file
38 subtag1 = subtag_value_a
40 subtag1 = subtag_value_b
42 subtag2 = subtag_value_c
52 Comments are delimited by a semicolon (';') or a hash ('#') character
53 at the beginning of the comment, and are terminated by the end of
56 Tags and values must be quoted using double quotes if they contain
57 spaces. Within a quoted string, the standard backslash interpretations
58 apply: "\en" (for the newline character),
59 "\et" (for the tab character), "\eb" (for the backspace character),
60 and "\e\e" (for the backslash character).
