to Fencer:
SMIRF can read and use it. But Smirf was built very tolerant towards violations of the PGN specification as long as the input will make any sense. Smirf is e.g. able to read notations written down in German instead of English. But there are some GUIs and tools which are very strict concerning PGN. As I told you SMIRF is already satisfied with the current status quo.
