Question,
I came across a workflow engine at an public ftp (government site) site back in late 1999 using Tcl as it core programming language. The only copyright notice is from a university.
What can be done with this. Since it was a public site, and no other notice of use was ever disclosed on the code or site...
It is a very good workflow engine.
I have rewritten the database connectivity to support ODBC, made it an extension, and added a few new features...
