Header Field Parser (hfp) for RFC 8315 conformant header fields. The header field is read from stdin. The input data must be an unfolded "Cancel-Lock" or "Cancel-Key" header field without line break at the end. The utility canlock-mhp(1) can be used to extract the field from an article. If such a header field is found, it is parsed according to the syntax defined in RFC 8315. If valid c-lock or c-key (respectively) elements are found, they are printed to stdout with SP (Space) as delimiter. Note: Additional formatting output is printed on stderr to make the output more human readable on a terminal. Redirect stderr to /dev/null if this is not wanted.
The following options are supported: -d Enable debug mode (messages are printed to stderr). -h Print help message, then exit. -n Prepend the data on stdout with the header field name (including the colon) and a SP (Space) delimiter. -v Print version and compile time options, then exit.
Zero on success or regular exit respectively. All other values indicate an error.
