3 # Tests for the variable modifier ':from=to', which replaces the suffix
4 # "from" with "to". It can also use '%' as a wildcard.
10 # A typical use case for the modifier ':from=to' is conversion of filename
16 # The modifier applies to each word on its own.

26 # The modifier ':from=to' is therefore often combined with the modifier ':M'.
31 # Another use case for the modifier ':from=to' is to append a suffix to each
38 # The modifier ':from=to' can also be used to surround each word by strings.
