Package grep-dctrl-1.10-23

The grep-dctrl program can answer such questions as * "What is the Debian package foo?" * "Which version of the Debian package bar is now current?" * "Which Debian packages does John Doe maintain?" * "Which Debian packages are somehow related to the Scheme programming language?" and with some help * "Who maintain the essential packages of a Debian system?" given a useful input file. It is a specialised grep program that is meant for processing any file which has the general format of a Debian package control file. These include the dpkg available file, the dpkg status file, and the Packages files on a distribution medium (such as a Debian CD-ROM or an FTP site carrying Debian).
