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.

NAME

       Dpkg::Vendor - get access to some vendor specific information

DESCRIPTION

       The files in /etc/dpkg/origins/ can provide information about various vendors who are providing Debian packages. Currently those files look
       like this:

	 Vendor: Debian
	 Vendor-URL: http://www.debian.org/
	 Bugs: debbugs://bugs.debian.org

       If the vendor derives from another vendor, the file should document the relationship by listing the base distribution in the Parent field:

	 Parent: Debian

       The file should be named according to the vendor name.

FUNCTIONS

       $fields = Dpkg::Vendor::get_vendor_info($name)
	   Returns a Dpkg::Control object with the information parsed from the corresponding vendor file in /etc/dpkg/origins/. If $name is
	   omitted, it will use /etc/dpkg/origins/default which is supposed to be a symlink to the vendor of the currently installed operating
	   system. Returns undef if there's no file for the given vendor.

       $name = Dpkg::Vendor::get_vendor_file($name)
	   Check if there's a file for the given vendor and returns its name.

       $name = Dpkg::Vendor::get_current_vendor()
	   Returns the name of the current vendor. If DEB_VENDOR is set, it uses that first, otherwise it falls back to parsing
	   /etc/dpkg/origins/default.  If that file doesn't exist, it returns undef.

       $object = Dpkg::Vendor::get_vendor_object($name)
	   Return the Dpkg::Vendor::* object of the corresponding vendor.  If $name is omitted, return the object of the current vendor.  If no
	   vendor can be identified, then return the Dpkg::Vendor::Default object.

       Dpkg::Vendor::run_vendor_hook($hookid, @params)
	   Run a hook implemented by the current vendor object.
