The Depot4 software has been applied in a number of projects.
Here are some comments from its users.
Originally, Depot4 was implemented by use of Niklaus Wirth's Oberon as a host programming language. Sorrily, this language was no real success in number of users. So we decided to maintain the JavaTM version of Depot4 only. However, an archive of last Oberon version (including examples and documents) is available from the downloads page.
