       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 debuild --  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.

       If debclean is invoked from a directory that is already a Debian source
       package, it will not descend into its subdirectories.

       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).
