Helper tool for other tools in the cms-meta-tools repo.
Reads path+filenames from standard input (one per line) and prints out those which make it through the filtering process. The filters are determined by a list of config files that are passed into the file_filter.py tool as arguments. These files are parsed in order, with later files possibly overriding values from earlier files. See file_filter_config.yaml.template for details on these config files and how the tool does its filtering based on them.
The location this tool is called from does not matter. It does not actually try to look at any of the files being read in from standard input. Its matching is based solely on their path and filenames.
