4. Extension functions
XML Calabash supports one extension function.
cwdfunction returns the “current working directory” of the processor. This function takes no arguments and does not depend on the context.
There are no XML Calabash steps that change the working directory, so this function is likely to return the same value every time it is called. However, there is nothing which prevents an extension step from being defined which changes the current working directory, so it is not necessarily the case that the same value will always be returned.
