----------
fresh : bool
If True, remove all existing build artifects and start afresh;
otherwise, only copy or build new or modified files. Default is
False.
report_total_errors : bool
If True, a line will be printed to stderr at the end of build
(assuming the function doesn't raise early) reporting the total
number of errors, e.g., "build finished with 0 errors". This is
turned on by default, but pass False to turn it off, which will
