Here are a few more details from an email exchange for those that are interested:
command line is just what is between quotes here: “combine tessdata/ eng." I forgot to mention that the source code for combine, which I have not modified, expects the “eng.” to be added. So, people like me and you have to copy and rename the files into tessdata, such as : copy normproto tessdata\eng.normproto Note that the name "combine" might not be permanent. Ray Smith might produce something else in the official distribution when he gets to wrapping up the training implementation.
