Here is the standard hierarchy of paths, as defined by the GNU Coding Standards:

  prefix
 	  exec_prefix
 	     bindir
 	     libdir
 	     libexecdir
 	     sbindir
 	  datadir
 	  sysconfdir
 	  sharestatedir
 	  localstatedir
 	  infodir
 	  lispdir
 	  includedir
 	  oldincludedir
 	  mandir

This macro will setup a set of variables of the form 'xxx_forward_relative_path' and 'xxx_backward_relative_path' where xxx is one of the above directories. The latter variable is set to the relative path to go from xxx to its parent directory, while the former hold the other way.

For instance `bindir_relative_path' will contains the value to add to $exec_prefix to reach the $bindir directory (usually 'bin'), and `bindir_backward_relative_path' the value to append to $bindir to reach the $exec_prefix directory (usually '..').

This macro requires adl_COMPUTE_RELATIVE_PATHS which itself requires adl_NORMALIZE_PATH.
