--header will be changed later today:
--header regexp
Use upto regexp as header. For normal usage the matched header
(typically the first line: --header '\n') will be split using --colsep
(which will default to '\t') and column names can be used as
replacement variables: {colname}. For --pipe the matched header will
be prepended to each output.
Please test this and give feed back on that.
