Bill, I think including code in an exception message is a mistake. This information is clearly geared to some one developing an ITK program.
I think it would be better to have a wiki page or a FAQ entry with what needs to be done to fix when there are no ImageIO factories registered. Then is exception message can just refer to that. Also there is the case when a developer using CMake did not correctly include the ITK_USE_FILE, we were getting a of those issues with ITK v4.0 first came out. Additionally, the user would have to register all the ImageIO, and TransformIO files. I have previously recommend copying the itkImageIOFactoryRegisterManager.h and the itkTransformIOFactoryRegisterManager.h files form the ITK build directory into the project to perform the factory registration. So my question, I thought some of the information was already in the WIKI some place? Anyone know where? Also the FAQ[1] looks unmaintained. Is this not a useful resource the community should help keep up to date? Is there a better location for this type of information?
