I'm not sure record should be where a version is specified. Let the user decide if they can disable a feature that requires a higher version of the file. That is, if the user does "--no-compression" or whatever we call it, then it will just save as version 6. Now what we should do, is to have a conversion command. trace-cmd convert <version> <input.dat> <output.dat> $ trace-cmd convert 6 trace-7.dat trace-6.dat We'll just have to document (probably in the convert man page) what features are added to which version, and how to set up the record to have it go to a lower version). -- Steve
