There has been a long standing usage of RFC2822 similar files in debian, especially the so called "control" file; Though even it has been widely used, there hasn't existed any formal, nor semi-formal specification regarding this format. So to look into this issue, this proposal targets to create a formal specification for the format.

Even though this specification targets to describe the format specified in the contol file primarily, there is a high chance that the final specification is incompatible with the format dpkg uses.
