+`basiliskiivm`
+==============
+by Morgan T. Aldridge <morgant@makkintosshu.com>
+
+OVERVIEW
+--------
+
+`basiliskiivm` is a quick utility I hacked together to package up [BasiliskII](https://github.com/cebix/macemu/) emulator prefs & disk images into a single `.basiliskiivm` directory to make them easier to manage, move, launch, and maintain multiple VMs.
