panoinfo is a simple utility built alongside the pano12 library that outputs a list of facts about the currently installed version of pano12. This is useful for debugging, especially on Windows, where it is sometimes difficult to guess which of a number of identically named DLL files is in use.

Here is a typical output, notice that the version of the library is, the maximum fisheye Field of View has been artificially limited to 160 degrees to prevent the use of fisheye lenses and that this version of the library has been built with Java support (note that these things are configurable if you build pano12 from sourcecode):
