NAME
       dpkg-source - Debian source package (.dsc) manipulation tool

SYNOPSIS
       dpkg-source [option...] command

DESCRIPTION
       dpkg-source packs and unpacks Debian source archives.

       None  of these commands allow multiple options to be combined into one,
       and they do not allow the value for an option  to  be  specified  in  a
       separate argument.

COMMANDS
       -x, --extract filename.dsc [output-directory]
              Extract  a  source  package (--extract since dpkg 1.17.14).  One
              non-option argument must be supplied, the  name  of  the  Debian
              source  control  file  (.dsc).   An  optional  second non-option
              argument may be supplied to specify the directory to extract the
              source  package  to, this must not exist. If no output directory
              is specified, the source package is extracted into  a  directory
              named source-version under the current working directory.

              dpkg-source  will  read the names of the other file(s) making up
              the source package from the control file; they are assumed to be
              in the same directory as the .dsc.

              The  files  in the extracted package will have their permissions
              and ownerships set to those which would have  been  expected  if
              the  files and directories had simply been created - directories
              and executable files will be 0777 and plain files will be  0666,
              both  modified by the extractors' umask; if the parent directory
              is setgid then the extracted directories will be  too,  and  all
              the files and directories will inherit its group ownership.

              If the source package uses a non-standard format (currently this
              means all formats except "1.0"), its  name  will  be  stored  in
              debian/source/format  so that the following builds of the source
              package use the same format by default.

       -b, --build directory [format-specific-parameters]
              Build a source package (--build since dpkg 1.17.14).  The  first
              non-option  argument  is  taken  as  the  name  of the directory
              containing the debianized source tree (i.e. with a  debian  sub-
              directory  and  maybe changes to the original files).  Depending
              on  the  source  package  format  used  to  build  the  package,
              additional parameters might be accepted.

              dpkg-source  will build the source package with the first format
              found in this  ordered  list:  the  format  indicated  with  the
              --format   command   line   option,   the  format  indicated  in
              debian/source/format,  "1.0".   The   fallback   to   "1.0"   is
              deprecated  and will be removed at some point in the future, you
              should  always   document   the   desired   source   format   in
              debian/source/format.  See section SOURCE PACKAGE FORMATS for an
              extensive description of the various source package formats.

       --print-format directory
              Print the source format that would be used to build  the  source
              package if dpkg-source --build directory was called (in the same
              conditions and with the same parameters; since dpkg 1.15.5).

       --before-build directory
              Run the corresponding hook of the source package  format  (since
              dpkg  1.15.8).   This  hook  is  called  before any build of the
              package (dpkg-buildpackage  calls  it  very  early  even  before
              debian/rules  clean).  This  command  is  idempotent  and can be
              called  multiple  times.  Not  all  source   formats   implement
              something  in  this  hook, and those that do usually prepare the
              source tree for the build  for  example  by  ensuring  that  the
              Debian patches are applied.

       --after-build directory
              Run  the  corresponding hook of the source package format (since
              dpkg 1.15.8).  This hook  is  called  after  any  build  of  the
              package  (dpkg-buildpackage  calls  it  last).  This  command is
              idempotent and can be called  multiple  times.  Not  all  source
              formats  implement  something  in  this  hook, and those that do
              usually use it to undo what --before-build has done.

       --commit [directory] ...
              Record changes in the source tree unpacked in  directory  (since
              dpkg  1.16.1).   This  command can take supplementary parameters
              depending on the source format.  It will error out  for  formats
              where this operation doesn't mean anything.

       -?, --help
              Show  the usage message and exit.  The format specific build and
              extract options can be shown by using the --format option.

       --version
              Show the version and exit.

OPTIONS
   Generic build options
       -ccontrol-file
              Specifies the main source control file to read information from.
              The  default is debian/control.  If given with relative pathname
              this is interpreted starting at  the  source  tree's  top  level
              directory.

       -lchangelog-file
              Specifies  the  changelog  file  to  read  information from. The
              default is debian/changelog.  If given  with  relative  pathname
              this  is  interpreted  starting  at  the source tree's top level
              directory.

       -Fchangelog-format
              Specifies    the    format     of     the     changelog.     See
              dpkg-parsechangelog(1)   for   information   about   alternative
              formats.

       --format=value
              Use the given format for building the source package (since dpkg
              1.14.17).     It    does    override   any   format   given   in
              debian/source/format.

       -Vname=value
              Set an output substitution variable.  See deb-substvars(5) for a
              discussion of output substitution.

       -Tsubstvars-file
              Read substitution variables in substvars-file; the default is to
              not read any file. This option can be  used  multiple  times  to
              read  substitution  variables  from  multiple  files (since dpkg
              1.15.6).

       -Dfield=value
              Override or add an output control file field.

       -Ufield
              Remove an output control file field.

       -Zcompression, --compression=compression
              Specify the compression to use for  created  tarballs  and  diff
              files  (--compression since dpkg 1.15.5).  Note that this option
              will not cause existing tarballs to  be  recompressed,  it  only
              affects  new  files. Supported values are: gzip, bzip2, lzma and
              xz.  The default is xz for formats 2.0 and newer, and  gzip  for
              format 1.0. xz is only supported since dpkg 1.15.5.

       -zlevel, --compression-level=level
              Compression   level   to  use  (--compression-level  since  dpkg
              1.15.5).  As with  -Z  it  only  affects  newly  created  files.
              Supported  values are: 1 to 9, best, and fast.  The default is 9
              for gzip and bzip2, 6 for xz and lzma.

       -i[regex], --diff-ignore[=regex]
              You may specify a perl regular expression  to  match  files  you
              want   filtered   out   of  the  list  of  files  for  the  diff
              (--diff-ignore since dpkg 1.15.6).  (This list is generated by a
              find  command.)  (If  the  source  package  is  being built as a
              version 3 source package using a VCS, this can be used to ignore
              uncommitted  changes  on  specific files. Using -i.* will ignore
              all of them.)

              The -i option by itself enables  this  setting  with  a  default
              regex  (preserving any modification to the default regex done by
              a previous use of --extend-diff-ignore)  that  will  filter  out
              control  files  and  directories  of  the  most  common revision
              control systems, backup and swap files and Libtool build  output
              directories.  There can only be one active regex, of multiple -i
              options only the last one will take effect.

              This is very helpful in cutting out extraneous  files  that  get
              included  in  the  diff,  e.g.  if you maintain your source in a
              revision control system and want to use a checkout  to  build  a
              source  package  without  including  the  additional  files  and
              directories that it will usually contain (e.g. CVS/, .cvsignore,
              .svn/). The default regex is already very exhaustive, but if you
              need to replace it, please note that by default it can match any
              part  of a path, so if you want to match the begin of a filename
              or only full filenames, you will need to provide  the  necessary
              anchors (e.g. '(^|/)', '($|/)') yourself.

       --extend-diff-ignore=regex
              The  perl  regular  expression specified will extend the default
              value used by --diff-ignore and its current value, if set (since
              dpkg  1.15.6).   It  does  this by concatenating "|regex" to the
              existing  value.   This  option  is   convenient   to   use   in
              debian/source/options  to exclude some auto-generated files from
              the automatic patch generation.

       -I[file-pattern], --tar-ignore[=file-pattern]
              If this option is specified,  the  pattern  will  be  passed  to
              tar(1)'s  --exclude  option  when  it  is  called  to generate a
              .orig.tar or .tar file (--tar-ignore since  dpkg  1.15.6).   For
              example,  -ICVS  will  make  tar  skip over CVS directories when
              generating a .tar.gz file. The option may be  repeated  multiple
              times to list multiple patterns to exclude.

              -I by itself adds default --exclude options that will filter out
              control files  and  directories  of  the  most  common  revision
              control  systems, backup and swap files and Libtool build output
              directories.

       Note: While they have similar purposes, -i and -I have  very  different
       syntax  and  semantics.  -i can only be specified once and takes a perl
       compatible  regular  expression  which  is  matched  against  the  full
       relative path of each file. -I can specified multiple times and takes a
       filename pattern with shell wildcards.  The pattern is applied  to  the
       full  relative path but also to each part of the path individually. The
       exact semantic of tar's --exclude option is somewhat  complicated,  see
       https://www.gnu.org/software/tar/manual/tar.html#wildcards  for  a full
       documentation.

       The default regex and patterns for both options  can  be  seen  in  the
       output of the --help command.

   Generic extract options
       --no-copy
              Do  not copy original tarballs near the extracted source package
              (since dpkg 1.14.17).

       --no-check
              Do not check signatures and checksums  before  unpacking  (since
              dpkg 1.14.17).

       --no-overwrite-dir
              Do  not  overwrite the extraction directory if it already exists
              (since dpkg 1.18.8).

       --require-valid-signature
              Refuse to unpack the source package if  it  doesn't  contain  an
              OpenPGP  signature  that  can  be  verified  (since dpkg 1.15.0)
              either with the  user's  trustedkeys.gpg  keyring,  one  of  the
              vendor-specific keyrings, or one of the official Debian keyrings
              (/usr/share/keyrings/debian-keyring.gpg                      and
              /usr/share/keyrings/debian-maintainers.gpg).

       --require-strong-checksums
              Refuse  to  unpack the source package if it does not contain any
              strong checksums (since dpkg 1.18.7).  Currently the only  known
              checksum considered strong is SHA-256.

       --ignore-bad-version
              Turns  the  bad  source  package  version check into a non-fatal
              warning  (since  dpkg  1.17.7).   This  option  should  only  be
              necessary  when  extracting  ancient source packages with broken
              versions, just for backwards compatibility.

SOURCE PACKAGE FORMATS
       If you don't know what source format to use, you should  probably  pick
       either      "3.0      (quilt)"      or     "3.0     (native)".      See
       https://wiki.debian.org/Projects/DebSrc3.0  for  information   on   the
       deployment of those formats within Debian.

   Format: 1.0
       A  source  package  in  this  format  consists either of a .orig.tar.gz
       associated to a .diff.gz or a single .tar.gz (in that case the  package
       is  said  to  be  native).   Optionally  the  original tarball might be
       accompanied  by  a  detached   upstream   signature   .orig.tar.gz.asc,
       extraction supported since dpkg 1.18.5.

       Extracting

       Extracting  a  native  package  is  a  simple  extraction of the single
       tarball in the target directory. Extracting  a  non-native  package  is
       done  by  first  unpacking the .orig.tar.gz and then applying the patch
       contained in the .diff.gz file. The timestamp of all patched  files  is
       reset  to  the  extraction  time  of  the  source  package (this avoids
       timestamp skews  leading  to  problems  when  autogenerated  files  are
       patched).  The diff can create new files (the whole debian directory is
       created that way) but can't remove files  (empty  files  will  be  left
       over).

       Building

       Building  a  native  package is just creating a single tarball with the
       source directory. Building a non-native package involves extracting the
       original  tarball  in a separate ".orig" directory and regenerating the
       .diff.gz by comparing the  source  package  directory  with  the  .orig
       directory.

       Build options (with --build):

       If  a  second  non-option argument is supplied it should be the name of
       the original source directory or tarfile or the  empty  string  if  the
       package  is a Debian-specific one and so has no debianization diffs. If
       no second argument is supplied  then  dpkg-source  will  look  for  the
       original  source  tarfile  package_upstream-version.orig.tar.gz  or the
       original  source  directory  directory.orig  depending   on   the   -sX
       arguments.

       -sa,  -sp,  -sk,  -su  and  -sr will not overwrite existing tarfiles or
       directories. If this is desired then -sA, -sP, -sK, -sU and -sR  should
       be used instead.

       -sk    Specifies to expect the original source as a tarfile, by default
              package_upstream-version.orig.tar.extension.  It will leave this
              original source in place as a tarfile, or copy it to the current
              directory if  it  isn't  already  there.  The  tarball  will  be
              unpacked into directory.orig for the generation of the diff.

       -sp    Like -sk but will remove the directory again afterwards.

       -su    Specifies  that  the original source is expected as a directory,
              by default package-upstream-version.orig  and  dpkg-source  will
              create a new original source archive from it.

       -sr    Like -su but will remove that directory after it has been used.

       -ss    Specifies  that  the  original  source  is  available  both as a
              directory and as a tarfile. dpkg-source will use  the  directory
              to  create  the  diff, but the tarfile to create the .dsc.  This
              option must be used with care - if the directory and tarfile  do
              not match a bad source archive will be generated.

       -sn    Specifies  to  not  look  for  any  original  source, and to not
              generate a diff.  The second argument, if supplied, must be  the
              empty string. This is used for Debian-specific packages which do
              not have a  separate  upstream  source  and  therefore  have  no
              debianization diffs.

       -sa or -sA
              Specifies  to  look for the original source archive as a tarfile
              or as a directory - the second argument, if any, may be  either,
              or  the  empty  string  (this is equivalent to using -sn).  If a
              tarfile is found it will unpack it to create the diff and remove
              it  afterwards  (this  is  equivalent to -sp); if a directory is
              found it will pack it to create the original source  and  remove
              it  afterwards  (this is equivalent to -sr); if neither is found
              it will assume that the package has no debianization diffs, only
              a  straightforward  source  archive (this is equivalent to -sn).
              If both are found then dpkg-source will  ignore  the  directory,
              overwriting it, if -sA was specified (this is equivalent to -sP)
              or raise an error if -sa was specified.  -sa is the default.

       --abort-on-upstream-changes
              The process fails if the  generated  diff  contains  changes  to
              files  outside  of the debian sub-directory (since dpkg 1.15.8).
              This option is not allowed in debian/source/options but  can  be
              used in debian/source/local-options.

       Extract options (with --extract):

       In all cases any existing original source tree will be removed.

       -sp    Used  when  extracting then the original source (if any) will be
              left as a tarfile. If it is not already located in  the  current
              directory  or if an existing but different file is there it will
              be copied there.  (This is the default).

       -su    Unpacks the original source tree.

       -sn    Ensures that the  original  source  is  neither  copied  to  the
              current  directory  nor  unpacked. Any original source tree that
              was in the current directory is still removed.

       All the -sX options are mutually exclusive. If you  specify  more  than
       one only the last one will be used.

       --skip-debianization
              Skips  application  of  the  debian  diff on top of the upstream
              sources (since dpkg 1.15.1).

   Format: 2.0
       Extraction supported since dpkg 1.13.9, building supported  since  dpkg
       1.14.8.   Also  known  as  wig&pen.  This format is not recommended for
       wide-spread usage, the format "3.0 (quilt)" replaces it.   Wig&pen  was
       the first specification of a new-generation source package format.

       The  behaviour  of  this format is the same as the "3.0 (quilt)" format
       except that it doesn't use an explicit list of patches.  All  files  in
       debian/patches/  matching  the  perl  regular expression [\w-]+ must be
       valid patches: they are applied at extraction time.

       When building a new source package, any change to the  upstream  source
       is stored in a patch named zz_debian-diff-auto.

   Format: 3.0 (native)
       Supported  since  dpkg  1.14.17.   This  format  is an extension of the
       native package format as defined in the 1.0  format.  It  supports  all
       compression  methods  and will ignore by default any VCS specific files
       and directories as well as many  temporary  files  (see  default  value
       associated to -I option in the --help output).

   Format: 3.0 (quilt)
       Supported since dpkg 1.14.17.  A source package in this format contains
       at least an original tarball (.orig.tar.ext where ext can be  gz,  bz2,
       lzma  and  xz)  and  a  debian  tarball  (.debian.tar.ext). It can also
       contain   additional   original   tarballs   (.orig-component.tar.ext).
       component  can  only  contain alphanumeric ('a-zA-Z0-9') characters and
       hyphens ('-').  Optionally each original tarball can be accompanied  by
       a     detached     upstream     signature     (.orig.tar.ext.asc    and
       .orig-component.tar.ext.asc), extraction supported since dpkg  1.17.20,
       building supported since dpkg 1.18.5.

       Extracting

       The  main  original  tarball  is  extracted  first, then all additional
       original tarballs are  extracted  in  subdirectories  named  after  the
       component  part  of  their  filename  (any  pre-existing  directory  is
       replaced). The debian  tarball  is  extracted  on  top  of  the  source
       directory  after  prior  removal  of any pre-existing debian directory.
       Note that the debian tarball must contain a debian sub-directory but it
       can   also   contain  binary  files  outside  of  that  directory  (see
       --include-binaries option).

       All    patches    listed     in     debian/patches/vendor.series     or
       debian/patches/series  are  then  applied,  where  vendor  will  be the
       lowercase name of the current vendor, or debian if there is  no  vendor
       defined.   If  the former file is used and the latter one doesn't exist
       (or is a symlink), then the latter is replaced with a  symlink  to  the
       former.   This is meant to simplify usage of quilt to manage the set of
       patches.  Vendor-specific series files are intended to make it possible
       to  serialize  multiple  development branches based on the vendor, in a
       declarative  way,  in  preference  to  open-coding  this  handling   in
       debian/rules.   This  is particularly useful when the source would need
       to be patched conditionally because the  affected  files  do  not  have
       built-in  conditional  occlusion  support.   Note  however  that  while
       dpkg-source parses correctly series files with  explicit  options  used
       for patch application (stored on each line after the patch filename and
       one or more spaces), it does ignore those  options  and  always  expect
       patches  that can be applied with the -p1 option of patch. It will thus
       emit a warning when it encounters such options, and the build is likely
       to fail.

       Note that lintian(1) will emit unconditional warnings when using vendor
       series due to a controversial Debian specific ruling, which should  not
       affect  any  external usage; to silence these, the dpkg lintian profile
       can be used by passing <<--profile dpkg>> to lintian(1).

       The timestamp of all patched files is reset to the extraction  time  of
       the  source  package  (this  avoids timestamp skews leading to problems
       when autogenerated files are patched).

       Contrary to quilt's default behaviour, patches are  expected  to  apply
       without  any  fuzz.  When that is not the case, you should refresh such
       patches with quilt, or dpkg-source will error out while trying to apply
       them.

       Similarly  to  quilt's  default behaviour, the patches can remove files
       too.

       The file .pc/applied-patches is  created  if  some  patches  have  been
       applied during the extraction.

       Building

       All original tarballs found in the current directory are extracted in a
       temporary directory by following the same logic as for the unpack,  the
       debian  directory  is  copied  over in the temporary directory, and all
       patches  except  the   automatic   patch   (debian-changes-version   or
       debian-changes,  depending  on  --single-debian-patch) are applied. The
       temporary directory is compared to the source package  directory.  When
       the  diff is non-empty, the build fails unless --single-debian-patch or
       --auto-commit has been used, in which case the diff is  stored  in  the
       automatic  patch.   If  the  automatic  patch  is created/deleted, it's
       added/removed from the series file and from the quilt metadata.

       Any change on a binary file is not representable in  a  diff  and  will
       thus  lead  to  a failure unless the maintainer deliberately decided to
       include that modified binary file in the debian tarball (by listing  it
       in  debian/source/include-binaries).  The  build  will  also fail if it
       finds binary files in the debian sub-directory unless  they  have  been
       whitelisted through debian/source/include-binaries.

       The  updated debian directory and the list of modified binaries is then
       used to generate the debian tarball.

       The  automatically  generated  diff  doesn't  include  changes  on  VCS
       specific  files  as  well  as  many  temporary files (see default value
       associated to -i option in the --help output). In particular,  the  .pc
       directory  used  by quilt is ignored during generation of the automatic
       patch.

       Note: dpkg-source --before-build (and --build)  will  ensure  that  all
       patches  listed  in the series file are applied so that a package build
       always has all patches applied.  It  does  this  by  finding  unapplied
       patches   (they   are   listed   in   the   series   file  but  not  in
       .pc/applied-patches), and if the first patch in that set can be applied
       without errors, it will apply them all. The option --no-preparation can
       be used to disable this behavior.

       Recording changes

       --commit [directory] [patch-name] [patch-file]
              Generates a patch corresponding to the local  changes  that  are
              not  managed  by the quilt patch system and integrates it in the
              patch system under the name patch-name. If the name is  missing,
              it  will  be  asked interactively. If patch-file is given, it is
              used  as  the  patch  corresponding  to  the  local  changes  to
              integrate.  Once  integrated,  an editor is launched so that you
              can edit the meta-information in the patch header.

              Passing patch-file is mainly useful after a build  failure  that
              pre-generated  this  file,  and on this ground the given file is
              removed after integration. Note also that the changes  contained
              in  the  patch file must already be applied on the tree and that
              the files modified by the  patch  must  not  have  supplementary
              unrecorded changes.

              If the patch generation detects modified binary files, they will
              be automatically added to debian/source/include-binaries so that
              they  end  up  in  the  debian tarball (exactly like dpkg-source
              --include-binaries --build would do).

       Build options

       --allow-version-of-quilt-db=version
              Allow dpkg-source to build the source package if the version  of
              the  quilt  metadata  is  the one specified, even if dpkg-source
              doesn't know about it (since dpkg 1.15.5.4).   Effectively  this
              says  that the given version of the quilt metadata is compatible
              with the version 2  that  dpkg-source  currently  supports.  The
              version of the quilt metadata is stored in .pc/.version.

       --include-removal
              Do   not   ignore   removed   files  and  include  them  in  the
              automatically generated patch.

       --include-timestamp
              Include timestamp in the automatically generated patch.

       --include-binaries
              Add all modified binaries in the debian tarball. Also  add  them
              to debian/source/include-binaries: they will be added by default
              in subsequent builds and this option is thus no more needed.

       --no-preparation
              Do not try to prepare the build tree by applying  patches  which
              are apparently unapplied (since dpkg 1.14.18).

       --single-debian-patch
              Use        debian/patches/debian-changes        instead       of
              debian/patches/debian-changes-version  for  the  name   of   the
              automatic  patch  generated  during build (since dpkg 1.15.5.4).
              This  option  is  particularly  useful  when  the   package   is
              maintained in a VCS and a patch set can't reliably be generated.
              Instead the current diff with upstream should  be  stored  in  a
              single     patch.     The     option    would    be    put    in
              debian/source/local-options  and  would  be  accompanied  by   a
              debian/source/local-patch-header  file explaining how the Debian
              changes can be best reviewed, for example in  the  VCS  that  is
              used.

       --create-empty-orig
              Automatically  create the main original tarball as empty if it's
              missing and if there are supplementary original tarballs  (since
              dpkg  1.15.6).   This option is meant to be used when the source
              package is just a bundle of multiple upstream software and where
              there's no "main" software.

       --no-unapply-patches, --unapply-patches
              By  default,  dpkg-source will automatically unapply the patches
              in  the  --after-build  hook  if  it  did  apply   them   during
              --before-build    (--unapply-patches    since    dpkg    1.15.8,
              --no-unapply-patches since dpkg 1.16.5).   Those  options  allow
              you  to  forcefully  disable  or  enable the patch unapplication
              process.    Those    options     are     only     allowed     in
              debian/source/local-options   so   that   all  generated  source
              packages have the same behavior by default.

       --abort-on-upstream-changes
              The process fails if  an  automatic  patch  has  been  generated
              (since dpkg 1.15.8).  This option can be used to ensure that all
              changes were properly recorded in separate quilt  patches  prior
              to  the  source  package  build.  This  option is not allowed in
              debian/source/options     but      can      be      used      in
              debian/source/local-options.

       --auto-commit
              The  process  doesn't  fail  if  an  automatic  patch  has  been
              generated,  instead  it's  immediately  recorded  in  the  quilt
              series.

       Extract options

       --skip-debianization
              Skips  extraction  of  the debian tarball on top of the upstream
              sources (since dpkg 1.15.1).

       --skip-patches
              Do not apply patches at the end of the  extraction  (since  dpkg
              1.14.18).

   Format: 3.0 (custom)
       Supported  since  dpkg  1.14.17.   This  format is special.  It doesn't
       represent a real source package format but can be used to create source
       packages with arbitrary files.

       Build options

       All  non-option  arguments  are  taken  as  files  to  integrate in the
       generated source package. They must exist and  are  preferably  in  the
       current directory. At least one file must be given.

       --target-format=value
              Required.  Defines  the  real  format  of  the  generated source
              package.  The generated .dsc file will contain this value in its
              Format field and not "3.0 (custom)".

   Format: 3.0 (git)
       Supported since dpkg 1.14.17.  This format is experimental.

       A  source  package  in this format consists of a single bundle of a git
       repository .git to hold the source of a package.  There may also  be  a
       .gitshallow file listing revisions for a shallow git clone.

       Extracting

       The  bundle  is cloned as a git repository to the target directory.  If
       there is a gitshallow file, it is installed as .git/shallow inside  the
       cloned git repository.

       Note  that  by  default  the  new  repository will have the same branch
       checked out that was checked out in the  original  source.   (Typically
       "master",  but  it  could  be  anything.)   Any  other branches will be
       available under remotes/origin/.

       Building

       Before going any further, some checks are done to ensure that we  don't
       have any non-ignored uncommitted changes.

       git-bundle(1)  is  used to generate a bundle of the git repository.  By
       default, all branches and tags in the repository are  included  in  the
       bundle.

       Build options

       --git-ref=ref
              Allows  specifying  a  git ref to include in the git bundle. Use
              disables the default behavior  of  including  all  branches  and
              tags.  May  be specified multiple times. The ref can be the name
              of a branch or tag to include. It may also be any parameter that
              can  be  passed to git-rev-list(1). For example, to include only
              the master branch, use --git-ref=master. To include all tags and
              branches,  except  for  the  private branch, use --git-ref=--all
              --git-ref=^private

       --git-depth=number
              Creates  a  shallow  clone  with  a  history  truncated  to  the
              specified number of revisions.

   Format: 3.0 (bzr)
       Supported  since  dpkg  1.14.17.   This  format  is  experimental.   It
       generates a single tarball containing the bzr repository.

       Extracting

       The tarball is unpacked and then bzr is used to  checkout  the  current
       branch.

       Building

       Before  going any further, some checks are done to ensure that we don't
       have any non-ignored uncommitted changes.

       Then the VCS specific part of the source directory is copied over to  a
       temporary  directory.  Before  this  temporary directory is packed in a
       tarball, various cleanup are done to save space.

DIAGNOSTICS
   no source format specified in debian/source/format
       The file debian/source/format should  always  exist  and  indicate  the
       desired  source  format.  For  backwards compatibility, format "1.0" is
       assumed when the file doesn't exist but you should not rely on this: at
       some point in the future dpkg-source will be modified to fail when that
       file doesn't exist.

       The rationale is that format "1.0" is no longer the recommended format,
       you  should  usually pick one of the newer formats ("3.0 (quilt)", "3.0
       (native)") but dpkg-source will not do this automatically for you.   If
       you want to continue using the old format, you should be explicit about
       it and put "1.0" in debian/source/format.

   the diff modifies the following upstream files
       When using source format "1.0" it is  usually  a  bad  idea  to  modify
       upstream  files  directly  as  the  changes  end  up  hidden and mostly
       undocumented in the  .diff.gz  file.  Instead  you  should  store  your
       changes  as  patches  in  the debian directory and apply them at build-
       time. To avoid this  complexity  you  can  also  use  the  format  "3.0
       (quilt)" that offers this natively.

   cannot represent change to file
       Changes  to  upstream  sources are usually stored with patch files, but
       not all changes can be represented with patches: they  can  only  alter
       the  content  of  plain  text  files.  If you try replacing a file with
       something of a different type (for example replacing a plain file  with
       a symlink or a directory), you will get this error message.

   newly created empty file file will not be represented in diff
       Empty  files can't be created with patch files. Thus this change is not
       recorded in the source package and you are warned about it.

   executable mode perms of file will not be represented in diff
       Patch files do not record permissions  of  files  and  thus  executable
       permissions  are not stored in the source package. This warning reminds
       you of that fact.

   special mode perms of file will not be represented in diff
       Patch files do not  record  permissions  of  files  and  thus  modified
       permissions  are not stored in the source package. This warning reminds
       you of that fact.

ENVIRONMENT
       DPKG_COLORS
              Sets the color mode (since dpkg 1.18.5).  The currently accepted
              values are: auto (default), always and never.

       DPKG_NLS
              If  set,  it  will  be used to decide whether to activate Native
              Language Support, also known as internationalization  (or  i18n)
              support  (since  dpkg 1.19.0).  The accepted values are: 0 and 1
              (default).

       SOURCE_DATE_EPOCH
              If set, it will be used as the timestamp (as seconds  since  the
              epoch) to clamp the mtime in the tar(5) file entries.

       VISUAL
       EDITOR Used by the "2.0" and "3.0 (quilt)" source format modules.

       GIT_DIR
       GIT_INDEX_FILE
       GIT_OBJECT_DIRECTORY
       GIT_ALTERNATE_OBJECT_DIRECTORIES
       GIT_WORK_TREE
              Used by the "3.0 (git)" source format modules.

FILES
   debian/source/format
       This  file  contains on a single line the format that should be used to
       build the source package (possible formats  are  described  above).  No
       leading or trailing spaces are allowed.

   debian/source/include-binaries
       This file contains a list of binary files (one per line) that should be
       included in  the  debian  tarball.  Leading  and  trailing  spaces  are
       stripped.  Lines starting with '#' are comments and are skipped.  Empty
       lines are ignored.

   debian/source/options
       This file contains a list of long options that should be  automatically
       prepended  to  the set of command line options of a dpkg-source --build
       or dpkg-source --print-format  call.  Options  like  --compression  and
       --compression-level are well suited for this file.

       Each  option  should  be  put on a separate line. Empty lines and lines
       starting with '#' are ignored.  The leading '--' should be stripped and
       short  options are not allowed.  Optional spaces are allowed around the
       '=' symbol and optional quotes are allowed around the value.  Here's an
       example of such a file:

         # let dpkg-source create a debian.tar.bz2 with maximal compression
         compression = "bzip2"
         compression-level = 9
         # use debian/patches/debian-changes as automatic patch
         single-debian-patch
         # ignore changes on config.{sub,guess}
         extend-diff-ignore = "(^|/)(config.sub|config.guess)$"

       Note:  format  options  are  not  accepted in this file, you should use
       debian/source/format instead.

   debian/source/local-options
       Exactly like debian/source/options except that the file is not included
       in the generated source package. It can be useful to store a preference
       tied to the maintainer or  to  the  VCS  repository  where  the  source
       package is maintained.

   debian/source/local-patch-header and debian/source/patch-header
       Free  form  text that is put on top of the automatic patch generated in
       formats "2.0" or "3.0 (quilt)". local-patch-header is not  included  in
       the generated source package while patch-header is.

   debian/patches/vendor.series
   debian/patches/series
       This  file  lists  all  patches  that  have to be applied (in the given
       order) on top of the upstream  source  package.  Leading  and  trailing
       spaces  are  stripped.   The  vendor  will be the lowercase name of the
       current vendor, or debian if  there  is  no  vendor  defined.   If  the
       vendor-specific series file does not exist, the vendor-less series file
       will be used.  Lines starting with '#' are comments  and  are  skipped.
       Empty  lines  are ignored.  Remaining lines start with a patch filename
       (relative to the debian/patches/  directory)  up  to  the  first  space
       character  or  the end of line. Optional quilt options can follow up to
       the end of line or the first '#' preceded by one or more spaces  (which
       marks the start of a comment up to the end of line).

BUGS
       The point at which field overriding occurs compared to certain standard
       output field settings is rather confused.
