/**
 * An Enum for ProcessStringEscapes option.
 * 
 * drools.parser.processStringEscapes = <true|false>
 * 
 * DEFAULT = true
 * 
 * When parsing a DRL file, drools will by default process the String escapes and
 * convert them into the appropriate character. For instance, if drools find a
 * "\n" inside a String, drools will convert that into a single new line character.
 * If you want that to show up as the two characters BACK_SLASH+N, you need to escape
 * the SLASH: "\\n", the same way you do in Java files.
 * 
 * This is different, though, from what happened in Drools 4. Drools 4 never processed
 * String escapes, making it impossible to encode special characters into Strings. But,
 * if for any reason, you need the Drools 4 behaviour when parsing files, just set this
 * option to NO (false).
