       deb-control - Debian GNU/Linux packages' master control file format


       This manual page is very out of date.

       Master control file format:

       The `control' file contains a number of fields.  Each field begins with
       a tag, such as `PACKAGE' or `VERSION' (case insensitive), followed by a
       colon, and the body of the field. Fields are delimited only by field
       tags.  In other words, field text may be multiple lines in length, but
       the installation tools will generally join lines when processing the
       body of the field.

       PACKAGE: <Short name of package>
              The value of this field is used to generate file names by some
              installation tools.

       VERSION: <Original version number>
              typically, this is the original portable package's version
              number in whatever form the program's author uses.

       PACKAGE_REVISION: <Debian package revision number>
              this should usually be a plain number, or perhaps two numbers
              separated by a full stop.

       MAINTAINER: <Name and e-mail address of package maintainer>
              should be in the format  Joe Bloggs <>.

       DESCRIPTION: <Description of package>

       DEPENDS: <Short names of prerequisite packages>
              list of packages that are required for this package to provide a
              non-trivial amount of functionality.  The package maintenance
              software will not allow a package to be installed without also
              installing packages listed in its DEPENDS field, and will rin
              the postinst scripts of packages listed in DEPENDS fields before
              those of the packages which depend on them, and run prerm
              scripts before.

       RECOMMENDED: <Short names of related, recommended packages>
              lists packages that would be found together with this one in all
              but unusual installations.  The package maintenance software
              will warn the user if they install a package without those
              listed in its RECOMMENDED field.

       The syntax of DEPENDS and RECOMMENDED is a list of groups of
       alternative packages.  Each group is a list of packages separated by
       vertical bar (or `pipe') symbols, `|'.  The groups are separated by
       commas.  Each package is a package name optionally followed by a
       version number specification in parentheses.  A version number may
       start with a `>', in which case any later version will match, and may
       specify or omit the Debian packaging revision (separated by a hyphen).
       Commas are to be read as `AND', and pipes as `OR', with pipes binding
       more tightly.

       OPTIONAL: <Short names of related, optional packages>
              lists packages that are related to this one and can perhaps
              enhance its usefulness, but without which installing this
              package is perfectly reasonable.  The package maintenance
              software will not moan at the user for not selecting OPTIONAL
              related packages, but may use the information in the OPTIONAL
              field to assist the user during package selection.

       CONFLICTS: <Short names of packages which conflict with this one>
              lists packages that conflict with this one, for example by
              containing files with the same names (an example would be Smail
              vs. Sendmail).  The package maintenance software will not allow
              conflicting packages to be installed.  Two conflicting packages
              should each include a CONFLICTS line mentioning the other.

       The syntax of OPTIONAL and CONFLICTS is a list of package names,
       separated by commas (and optional whitespace).  In the CONFLICTS field,
       the comma should be read as `OR'.

       This manpage is seriously out of date.
