The Glulx specification was written by Andrew Plotkin as an attempt to define a format for interactive fiction games that the Inform compiler could compile to, without the limitations of its original output format, Infocom's Z-Machine.

Windows Glulxe is based on Andrew's Glulxe 0.6.1, which is a complete implementation of version 3.1.3 of the Glulx specification.
