Dpkg::Path(3)                    libdpkg-perl                    Dpkg::Path(3)

       Dpkg::Path - some common path handling functions

       It provides some functions to handle various path.

               This function will scan upwards the hierarchy of directory to
               find out the directory which contains the "DEBIAN" sub-
               directory and it will return its path. This directory is the
               root directory of a package being built.

               If no DEBIAN subdirectory is found, it will return undef.

               Returns the filename relative to get_pkg_root_dir($file).

               This function tries to guess the root directory of the package
               build tree.  It will first use get_pkg_root_dir(), but it will
               fallback to a more imprecise check: namely it will use the
               parent directory that is a sub-directory of the debian

               It can still return undef if a file outside of the debian sub-
               directory is provided.

       check_files_are_the_same($file1, $file2, $resolve_symlink)
               This function verifies that both files are the same by checking
               that the device numbers and the inode numbers returned by
               stat()/lstat() are the same. If $resolve_symlink is true then
               stat() is used, otherwise lstat() is used.

               This function returns a cleaned path. It simplifies double //,
               and remove /./ and /../ intelligently. For /../ it simplifies
               the path only if the previous element is not a symlink. Thus it
               should only be used on real filenames.

       $newpath = resolve_symlink($symlink)
               Return the filename of the file pointed by the symlink. The new
               name is canonicalized by canonpath().

       my $cmdpath = find_command($command)
               Return the path of the command if defined and available on an
               absolute or relative path or on the $PATH, undef otherwise.

       my $control_file = get_control_path($pkg, $filetype)
               Return the path of the control file of type $filetype for the
               given package.

       my @control_files = get_control_path($pkg)
               Return the path of all available control files for the given

       my $file = find_build_file($basename)
               Selects the right variant of the given file: the arch-specific
               variant ("$basename.$arch") has priority over the OS-specific
               variant ("$basename.$os") which has priority over the default
               variant ("$basename"). If none of the files exists, then it
               returns undef.

       my @files = find_build_file($basename)
               Return the available variants of the given file. Returns an
               empty list if none of the files exists.

   Version 1.04
       Update semantics: find_command() now handles an empty or undef

   Version 1.03
       New function: find_build_file()

   Version 1.02
       New function: get_control_path()

   Version 1.01
       New function: find_command()

   Version 1.00
       Mark the module as public.
