формат главного управляющего файла пакетов исходного кода Debian (Debian source packages' master control file format)
USER-DEFINED FIELDS
It is allowed to add additional user-defined fields to the
control file. The tools will ignore these fields. If you want the
fields to be copied over to the output files, such as the binary
packages, you need to use a custom naming scheme: the fields
should start with an X, followed by zero or more of the letters
SBC and a hyphen.
S The field will appear in the source package control file,
see dsc(5).
B The field will appear in the control file in the binary
package, see deb-control(5).
C The field will appear in the upload control (.changes)
file, see deb-changes(5).
Note that the X[SBC]- prefixes are stripped when the fields are
copied over to the output files. A field XC-Approved-By will
appear as Approved-By in the changes file and will not appear in
the binary or source package control files.
Take into account that these user-defined fields will be using
the global namespace, which might at some point in the future
collide with officially recognized fields. To avoid such
potential situation you can prefix those fields with Private-,
such as XB-Private-New-Field.
