Constructor Details

#initialize(string, opts = {}) ⇒ AsciiParser

string - the plist string to parse

options hash:

 :parse_numbers => true/false   :  Set this to true if you numeric values (float/ints) as the correct Ruby type
 :parse_booleans => true/false  :  Set this to true if you want "true" and "false" to return the boolean Ruby types

Note:  Apple's parsers return strings for all old-style plist types.

Raises:
