/ represents a stressed syllable,
X represents an unstressed syllable.
Some words have multiple pronunciations. A number in parentheses (eg
{0}) at the end of a word specifies a pronunciation. When matching
a word with its pronunciation, only letters and ' are considered.
This means that the matching can be modified by changing ' to
`. Only space, dash, and underscore denote new words so, by
modifying the apostrophe, the two sides will be checked together. For example,
changing pickin' to pickin`[g] causes it to be matched
as picking. When a word isn't recognized, its meter is marked as a
?. To change this, denote the correct stress pattern at the end of
the word inside curly braces, using * instead of X to
represent a unstressed syllable (eg pickin'{/*}).
