I happened upon a slick extensible UML tool for Windows called UMLStudio and
liked it enough to write a script to generate Ada 95 code from the diagrams.
It doesn't reverse engineer Ada but if enough of us asked, perhaps they would!
See www.pragsoft.com\download.html for both the script and a trial version of
the program. Let them know that Ada reverse engineering would be worthwhile!
PS: I get no compensation from them and have no stake in their company.
