Old third-party code might still compare the relation with the
previously used relations (<<,<=,==,!=,>=,>>,) instead of the curently
used ones (<,<=,=,!=,>=,>,). This compare helper lets < match to <<,
> match to >> and = match to ==.

dS )r) a" Record in a Packages file
Represent a record as stored in a Packages file. You can use this like
a dictionary mapping the field names of the record to their values::
>>> record = Record("Package: python-apt\nVersion: 0.8.0\n\n")
>>> record["Package"]
'python-apt'
>>> record["Version"]
'0.8.0'
For example, to get the tasks of a package from a cache, you could do::
package.candidate.record["Tasks"].split()
Of course, you can also use the :attr:`Version.tasks` property.

r� t Y Y S X Y nX dS )a: Compares against another apt.Version object or a version string.
This method behaves like Python 2's cmp builtin and returns an integer
according to the outcome. The return value is negative in case of
self < other, zero if self == other and positive if self > other.
The comparison includes the package name and architecture if other is
an apt.Version object. If other isn't an apt.Version object it'll be
assumed that other is a version string (without package name/arch).

dS )r+ a� Provide a mapping & sequence interface to all versions of a package.
This class can be used like a dictionary, where version strings are the
keys. It can also be used as a sequence, where integers are the keys.
You can also convert this to a dictionary or a list, using the usual way
of dict(version_list) or list(version_list). This is useful if you need
to access the version objects multiple times, because they do not have to
be recreated this way.
Examples ('package.versions' being a version list):
'0.7.92' in package.versions # Check whether 0.7.92 is a valid version.
package.versions[0] # Return first version or raise IndexError
package.versions[0:2] # Return a new VersionList for objects 0-2
package.versions['0.7.92'] # Return version 0.7.92 or raise KeyError
package.versions.keys() # All keys, as strings.
max(package.versions)

This is now the package's architecture in the multi-arch sense,
previously it was the architecture of the candidate version

Download the changelog of the package and return it as unicode
string.
The parameter *uri* refers to the uri of the changelog file. It may
contain multiple named variables which will be substitued. These
variables are (src_section, prefix, src_pkg, src_ver). An example is
the Ubuntu changelog::
"http://changelogs.ubuntu.com/changelogs/pool" \
"/%(src_section)s/%(prefix)s/%(src_pkg)s" \
"/%(src_pkg)s_%(src_ver)s/changelog"
The parameter *cancel_lock* refers to an instance of threading.Event,
which if set, prevents the download.
