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).
