       debclean - clean up a sourcecode tree

       debclean [options]

       debclean  walks  through  the  directory tree starting at the directory
       tree in which it was invoked, and executes debian/rules clean for  each
       Debian  source directory encountered.  These directories are recognised
       by containing a debian/changelog file for a package whose name  matches
       that of the directory.  Name matching is described below.

       Also,  if the --cleandebs option is given, then in every directory con-
       taining a Debian source tree, all  files  named  *.deb,  *.changes  and
       *.build  are  removed.  The .dsc, .diff.gz and the (.orig).tar.gz files
       are not touched so that the release can be reconstructed if  necessary,
       and  the  .upload files are left so that debchange functions correctly.
       The --nocleandebs option prevents this extra cleaning behaviour and the
       --cleandebs option forces it.  The default is not to clean these files.

       debclean uses debuild(1) to clean the source tree.

Directory name checking
       In  common  with  several other scripts in the devscripts package, deb-
       clean  will   walk   through   the   directory   tree   searching   for
       debian/changelog  files.   As  a  safeguard against stray files causing
       potential problems, it will examine the name of  the  parent  directory
       once  it  finds  a  debian/changelog file, and check that the directory
       name corresponds to the package name.  Precisely how it  does  this  is
       controlled      by      two      configuration      file      variables
       their  corresponding  command-line  options  --check-dirname-level  and

       DEVSCRIPTS_CHECK_DIRNAME_LEVEL can take the following values:

       0      Never check the directory name.

       1      Only check the directory name if we have had to change directory
              in  our search for debian/changelog.  This is the default behav-

       2      Always check the directory name.

       The directory name is checked by testing whether the current  directory
       name  (as determined by pwd(1)) matches the regex given by the configu-
       ration file option DEVSCRIPTS_CHECK_DIRNAME_REGEX  or  by  the  command
       line  option  --check-dirname-regex  regex.  Here regex is a Perl regex
       (see perlre(3perl)), which will be anchored at the  beginning  and  the
       end.   If  regex  contains a '/', then it must match the full directory
       path.  If not, then it must match the full directory  name.   If  regex
       contains  the  string  'PACKAGE',  this  will be replaced by the source
       package name, as determined from the changelog.  The default value  for
       the  regex  is:  'PACKAGE(-.+)?', thus matching directory names such as
       PACKAGE and PACKAGE-version.

              Also remove all .deb, .changes and .build files from the  parent

              Do  not remove the .deb, .changes and .build files from the par-
              ent directory; this is the default behaviour.

       --check-dirname-level N
              See the above section Directory name checking for an explanation
              of this option.

       --check-dirname-regex regex
              See the above section Directory name checking for an explanation
              of this option.

       --no-conf, --noconf
              Do not read any configuration files.  This can only be  used  as
              the first option given on the command-line.

       -d     Do not run dpkg-checkbuilddeps to check build dependencies.

       --help Display a help message and exit successfully.

              Display version and copyright information and exit successfully.

       The  two configuration files /etc/devscripts.conf and ~/.devscripts are
       sourced in that order to set  configuration  variables.   Command  line
       options  can be used to override configuration file settings.  Environ-
       ment variable settings are ignored for  this  purpose.   The  currently
       recognised variables are:

              If  this  is  set to yes, then it is the same as the --cleandebs
              command line parameter being used.

              See the above section Directory name checking for an explanation
              of these variables.  Note that these are package-wide configura-
              tion variables, and will therefore affect all devscripts scripts
              which  check  their value, as described in their respective man-
              pages and in devscripts.conf(5).
