Deepak Kodihalli160d3e02017-01-17 04:25:22 -06004This script will parse error log yaml file(s) and generate
Andrew Geisslerc830e0f2016-10-18 12:51:29 -05005a header file which will then be used by the error logging client and
6server to collect and validate the error information generated by the
7openbmc software components.
8
9This code uses a mako template to provide the basic template of the header
10file we're going to generate. We then call it with information from the
11yaml to generate the header file.
