       dsc - Debian source packages' control file format




       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


       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              This field has now been superseded by the Package-List field,  which  gives  enough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

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

       Maintainer: fullname-email (recommended)
              Should be in the format “Joe Bloggs <>”, and is typically the person
              who created the package, as  opposed  to  the  author  of  the  software  that  was

       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
              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

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

              The package is the binary package name.

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

              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 ‘,’.

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

                     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.


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