Many keywords in libraries distributed with Robot Framework accept optional flag-like arguments that are defined like option=False. How to enable such option depends slightly on the library. To make the situation more consistent, we have decided to use implement a generic utility function that all libraries can use that behaves like this:

• With non-string values, just return results of bool(value).
• Consider empty string and strings false and no (case-insensitively) to be False and other strings True.

All libraries using the new utility will also need a generic documentation section explaining the usage.

Libraries to go through:

• BuiltIn
• Collections
• DateTime
• Dialogs
• OperatingSystem
• Process
• Screenshot
• String
• Telnet
• XML
