This program will use the 3 provided versions of the Debian
changelog to generate a merged changelog file. The resulting
changelog is stored in the file out or output to the standard
output if that parameter is not given.
Each entry is identified by its version number and they are
assumed to be not conflicting, they are simply merged in the
right order (by decreasing version number). When
--merge-prereleases is used, the part of the version number after
the last tilde is dropped so that 1.0-1~exp1 and 1.0-1~exp5 are
considered to be the same entry. When the same version is
available in both new-a and new-b, a standard line-based 3-way
merge is attempted (provided that the module Algorithm::Merge is
available — it's part of the package libalgorithm-merge-perl —
otherwise you get a global conflict on the content of the entry).
Drop the part after the last tilde in the version number
when doing version comparison to identify if two entries
are supposed to be the same or not.
This is useful when you keep using the same changelog
entry but you increase its version number regularly. For
instance, you might have 2.3-1~exp1, 2.3-1~exp2, ... until
the official release 2.3-1 and they are all the same
changelog entry that has evolved over time.

If you want to use this program to merge Debian changelog files
in a git repository, you have first to register a new merge
driver in .git/config or ~/.gitconfig:
name = debian/changelog merge driver
driver = dpkg-mergechangelogs -m %O %A %B %A
Then you have to setup the merge attribute for the
debian/changelog file either in .gitattributes in the repository
itself, or in .git/info/attributes:
