ProDOS file system for FUSE
## End of Life Notice
This software, while usable, is EOL. No further updates are expected.
ProFUSE 2.0, featuring read/write support for ProDOS and HFS, is available as part of
[Golden Gate](http://golden-gate.ksherlock.com)
See the Wiki for details about the ProDOS file system.
