I don't use WDSibyl but I noticed it has been updated on Netlabs ftp site as of 2006-03-18. There are both OS/2 and Win32 sources and binaries. Help appears to be in both German and English though the history.txt is in German. ftp://ftp.netlabs.org/pub/wdsibyl/wdsibyl/History.txt I am not sure what has changed but there area number of updated files in the different zip archives.
The Web site for WDSibyl http://members.chello.at/webstar/wdsibyl.html
doesn't appear to have been updated as of yet. "This is a Pascal-Compiler which processes a language closely related to ?Delphi½."
