The templatizer is a program I wrote which would take a "template" file containing formulas for component families and such and convert it into a full-fledged SE4 data file. The latest version is version 4.0.0, but unfortunately that version was lost, and the previous version, version 3.0.5, is a bit of a pain to get running in Windows, as it relies on a GNU C mathematical library to run. (Previous versions used my own mathematical library, which was very buggy; version 4 used a Java mathematical library. I started working on a version 5 which would have had a graphical user interface, but gave up on that

) I think I might still have version 3.0.5 (or at least some version near it) at school, though...
Of course, the templatizer will hopefully be rendered obsolete when SE5 comes out, as we're supposed to have formula parsing integrated directly into the data files
