There has been some confusion about where to put confidential
information in problem reports sent with send-pr. If you submit
a problem report to Cygnus, and you want its detailed contents to remain
confidential, set the `>Confidential:' field to `yes'.
However, the `Subject:' line in the mail header and the `>Synopsis:' field in the body of the PR are not treated as confidential information, as they are used when we compile reports, such as the list of Fixed Problems in this manual (see section Problems fixed in this release). Do not put confidential information in these fields. Any code samples, machine descriptions, problem details, and so on of course remain strictly confidential in any problem report marked as such.
The mail query server for problem reports never reports any information from confidential bug reports.
