Dusk OS and Collapse OS were created by Virgil Dupras.

I was not entirely alone in creating it though. Some people wrote significant
parts of it:

Michael Schierl
  - Framebuffer grid (io/fbgrid)
  - WASM port
  - Usermode Dusk
  - Oberon emulator (emul/oberon)
  - CUA text editor (text/gedx)
  - System Clipboard (text/clip)

Arcade Wise
  - PC driver for CMOS real time clock (drv/pc/rtc)

Other people have made smaller contributions and are listed below in order
of "appearance". To know the nature of those contributions, look
in the history of the git repository. In the case of old Collapse OS
contributions, look in one of the old Collapse OS archives under AUTHORS.
