NAME
       Dpkg::Path - some common path handling functions

DESCRIPTION
       It provides some functions to handle various path.

METHODS
       get_pkg_root_dir($file)
	       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.

       relative_to_pkg_root($file)
	       Returns the filename relative to get_pkg_root_dir($file).

       guess_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
	       directory.

	       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.

       canonpath($file)
	       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 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
	       package.

       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.
