+Description: lightweight Exim MTA (v4) daemon
+ Exim (v4) is a mail transport agent. This package contains the exim4
+ daemon with only basic features enabled. It works well with the
+ standard setups that are provided by Debian and includes support for
+ TLS encryption and the dlopen patch to allow dynamic loading of a
+ local_scan function.
+ .
+ The Debian exim4 packages have their own web page,
+ http://pkg-exim4.alioth.debian.org/. There is also a Debian-specific
+ FAQ list. Information about the way the Debian packages are
+ configured can be found in
+ /usr/share/doc/exim4-base/README.Debian.gz, which additionally contains
+ information about the way the Debian binary packages are built. The
+ very extensive upstream documentation is shipped in
+ /usr/share/doc/exim4-base/spec.txt.gz. To repeat the debconf-driven
+ configuration process in a standard setup, invoke dpkg-reconfigure
+ exim4-config. There is a Debian-centered mailing list,
+ pkg-exim4-users@lists.alioth.debian.org. Please ask Debian-specific
+ questions there, and only write to the upstream exim-users mailing
+ list if you are sure that your question is not Debian-specific. You
+ can find the subscription web page on
+ http://lists.alioth.debian.org/mailman/listinfo/pkg-exim4-users

+Description: High-performance mail transport agent
+ Postfix is Wietse Venema's mail transport agent that started life as an
+ alternative to the widely-used Sendmail program.  Postfix attempts to
+ be fast, easy to administer, and secure, while at the same time being
+ sendmail compatible enough to not upset existing users. Thus, the outside
+ has a sendmail-ish flavor, but the inside is completely different.

+Description: Advanced front-end for dpkg
+ This is Debian's next generation front-end for the dpkg package manager.
+ It provides the apt-get utility and APT dselect method that provides a
+ simpler, safer way to install and upgrade packages.
+ .
+ APT features complete installation ordering, multiple source capability
+ and several other unique features, see the Users Guide in apt-doc.

+Description: High-performance mail transport agent
+ Postfix is Wietse Venema's mail transport agent that started life as an
+  alternative to the widely-used Sendmail program.  Postfix attempts to
+  be fast, easy to administer, and secure, while at the same time being
+  sendmail compatible enough to not upset existing users. Thus, the outside
+  has a sendmail-ish flavor, but the inside is completely different.

+Description: Multi-arch = allowed package, no dependency
+ This is a multiarch package. By default it can only satisfy dependencies for
+ packages of the same architecture but that can be changed with ':any'
+ dependencies.
+ .
+ It can only be installed for one architecture at a time. Trying to install the
+ same package for another architecture will remove the first one.
+ .
+ Packages providing tools or shells typically fall into this category.
