NAME
       dsc - Debian source packages' control file format

SYNOPSIS
       filename.dsc

DESCRIPTION
       Each  Debian  source  package is composed of a .dsc control file, which
       contains a number of fields.  Each field begins with  a  tag,  such  as
       Source  or Binary (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
       (except   in   case   of  the  multiline  fields  Package-List,  Files,
       Checksums-Sha1 and Checksums-Sha256, see below).

       The control  data  might  be  enclosed  in  an  OpenPGP  ASCII  Armored
       signature, as specified in RFC4880.

FIELDS
       Format: format-version (required)
              The  value  of  this  field  declares  the format version of the
              source package.  The field value is used by programs acting on a
              source  package  to  interpret  the  list of files in the source
              package and determine how to unpack it.  The syntax of the field
              value  is  a  numeric  major revision, a period, a numeric minor
              revision, and then an optional subtype after  whitespace,  which
              if  specified  is  an  alphanumeric  word  in  parentheses.  The
              subtype is optional in the  syntax  but  may  be  mandatory  for
              particular source format revisions.

              The source formats currently supported by dpkg are 1.0, 2.0, 3.0
              (native), 3.0 (quilt), 3.0 (git), 3.0 (bzr) and 3.0 (custom).

       Source: source-name (required)
              The value of this field determines the package name, and is used
              to generate file names by most installation tools.

       Binary: binary-package-list
              This  folded  field  lists  binary  packages  which  this source
              package can produce, separated by commas.

              This field has now been superseded by  the  Package-List  field,
              which  gives  enough  information about what binary packages are
              produced on which architecture, build-profile and other involved
              restrictions.

       Architecture: arch-list (recommended)
              A  list of architectures and architecture wildcards separated by
              spaces which specify the type of hardware this  package  can  be
              compiled   for.   Common  architecture  names  and  architecture
              wildcards are amd64, armel, i386, linux-any, any-amd64, etc.

              Note  that  the  all  value  is  meant  for  packages  that  are
              architecture   independent,   and  any  for  packages  that  are
              architecture dependent.  The list may include (or consist solely
              of)   the  special  value  all.   When  the  list  contains  the
              architecture wildcard any, the only other value allowed  in  the
              list is all.

              The  field value is generally generated from Architecture fields
              from in the debian/control in the source package.

       Version: version-string (required)
              Typically, this is the  original  package's  version  number  in
              whatever  form the program's author uses.  It may also include a
              Debian revision number (for  non-native  packages).   The  exact
              format and sorting algorithm are described in deb-version(7).

       Origin: name
              The name of the distribution this package is originating from.

       Maintainer: fullname-email (recommended)
              Should  be  in the format "Joe Bloggs <jbloggs@foo.com>", and is
              typically the person who created the package, as opposed to  the
              author of the software that was packaged.

       Uploaders: fullname-email-list
              Lists all the names and email addresses of co-maintainers of the
              package, in the same format as the Maintainer  field.   Multiple
              co-maintainers should be separated by a comma.

       Description short-description
        long-description
              The  format  for the source package description is a short brief
              summary on the first line (after the  Description  field).   The
              following  lines  should  be  used  as  a  longer, more detailed
              description.  Each line of the long description must be preceded
              by a space, and blank lines in the long description must contain
              a single '.' following the preceding space.

       Homepage: url
              The upstream project home page url.

       Standards-Version: version-string (recommended)
              This documents the  most  recent  version  of  the  distribution
              policy standards this package complies with.

       Vcs-Browser: url
              The  url of a web interface to browse the Version Control System
              repository.

       Vcs-Arch: url
       Vcs-Bzr: url
       Vcs-Cvs: url
       Vcs-Darcs: url
       Vcs-Git: url
       Vcs-Hg: url
       Vcs-Mtn: url
       Vcs-Svn: url
              These fields declare the  url  of  the  Version  Control  System
              repository    used    to    maintain    this    package.     See
              deb-src-control(5) for more details.

       Testsuite: name-list
              This  field  declares  that  the  source  package  contains  the
              specified  test  suites.  The value is a comma-separated list of
              test  suites.   If  the  autopkgtest   value   is   present,   a
              debian/tests/control  is  expected to be present, if the file is
              present but not the value, then dpkg-source  will  automatically
              add it, preserving previous values.

       Testsuite-Triggers: package-list
              This  field  declares  the  comma-separated  union  of  all test
              dependencies (Depends fields in debian/tests/control file), with
              all  restrictions removed, and OR dependencies flattened, except
              for  binaries  generated  by  this  source  package  and   meta-
              dependencies such as @ or @builddeps@.

              Rationale:  this field is needed because otherwise to be able to
              get the test dependencies, each source package would need to  be
              unpacked.

       Build-Depends: package-list
       Build-Depends-Arch: package-list
       Build-Depends-Indep: package-list
       Build-Conflicts: package-list
       Build-Conflicts-Arch: package-list
       Build-Conflicts-Indep: package-list
              These  fields  declare  relationships between the source package
              and packages used to  build  it.   They  are  discussed  in  the
              deb-src-control(5) manpage.

       Package-List:
        package package-type section priority key-value-list
              This   multiline  field  contains  a  list  of  binary  packages
              generated by this source package.

              The package is the binary package name.

              The package-type  is  the  binary  package  type,  usually  deb,
              another common value is udeb.

              The  section and priority match the binary package fields of the
              same name.

              The key-value-list is a space separated key=value list, and  the
              currently known optional keys are:

              arch   The  architecture  restriction  from  the  binary package
                     Architecture field, with spaces converted to ','.

              profile
                     The normalized build-profile restriction formula from the
                     binary package Build-Profile field, with ORs converted to
                     '+' and ANDs to ','.

              essential
                     If the binary package is essential, this key will contain
                     the value of the Essential field, that is a yes value.

       Files: (required)
       Checksums-Sha1: (required)
       Checksums-Sha256: (required)
        checksum size filename
              These  multiline  fields contain a list of files with a checksum
              and size for each one.  These fields have the  same  syntax  and
              differ only in the checksum algorithm used: MD5 for Files, SHA-1
              for Checksums-Sha1 and SHA-256 for Checksums-Sha256.

              The first line of the field value (the part on the same line  as
              the  field  name  followed  by  a  colon)  is always empty.  The
              content of the field is expressed  as  continuation  lines,  one
              line per file.  Each line consists of the checksum, a space, the
              file size, a space, and the file name.

              These fields list all files that make  up  the  source  package.
              The  list  of files in these fields must match the list of files
              in the other related fields.

BUGS
       The Format field conflates the format for the .dsc file itself and  the
       format of the extracted source package.
