/ represents a stressed syllable,
X represents an unstressed syllable.
Some words have multiple pronunciations. If a syllable can either be stressed
or not depending on the pronunciation chosen, the meter is instead marked as
\. 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'{/*}).
