 This package provides the low-level infrastructure for handling the
 installation and removal of Debian software packages.
 .
 For Debian package development tools, install dpkg-dev.

 This package provides the development tools (including dpkg-source)
 required to unpack, build and upload Debian source packages.
 .
 Most Debian source packages will require additional tools to build;
 for example, most packages need make and the C compiler gcc.

 dselect is a high-level interface for managing the installation and
 removal of Debian software packages.
 .
 Many users find dselect intimidating and new users may prefer to use
 apt-based user interfaces.
