The following options can be used to influence the output of
the changelog parser, e.g. the range of entries or the format
of the output. They need to be supported by the parser script
in question. See also CAVEATS.
Set the output format. Currently supported values are
dpkg and rfc822.
dpkg is the classic output format (from before this

in Debian control format (see deb-control(5)). If more
than one entry is requested, then most fields are taken from the
latest entry, except otherwise stated:
Source: <pkg name>
Distribution: <target distribution>
The highest urgency of all included entries is used.
Closes: <bug number>
The Closes fields of all included entries are merged.
Changes: <changelog entries>
The text of all changelog entries is concatenated. To make
this field a valid Debian control format multiline field
empty lines are replaced with a single full stop and all lines
is intended by one space character. The exact content depends
on the changelog format.
There might be additional user-defined fields present.
The rfc822 format uses the same fields but outputs
a separate paragraph for each changelog entry so that all
metadata for each entry is preserved.
