The product I am talking about is Signiant:http://www.signiant.com/.
It's a file based workflow application that basically that is written in Perl in the same sense that emacs is written in emacs lisp. The idea is for people to write workflows in the embedded Perl environment which is the same across of the machines on which Signiant is installed. I could use another interpretor, but that would require extra work and I wouldn't be able to use a lot of the Signiant specific code.
