0.91.1 posted

I posted the 0.91.1 source and mac build. Please test it out. I held off on the announcement since I haven't built the windows binaries.
      I did run into several problems that stemmed from files not being mentioned in "MANIFEST.in". Some included "CXX/*.h", "ttconv/*.h" and "setup.cfg.template". Basically these files were not being included in the sdist output. I thought I would mention it in case people notice missing files.
