-# A problem with this script is that we must be able to handle symbolic
-# links somewhere in the paths of either path.  To resolve symlinks we use
-# the `pwd' program.  But some `pwd' programs are no real programs but
-# instead aliases (defined by the user) or builtins (as in bash-2).  Both
-# kinds have in common that they might not give the correct result.  E.g.,
-# the builtin in bash-2 returns the path which was used to change to the
-# directory and not the real path.
-#
-# To prevent this problem we make sure the real `pwd' somewhere in the
-# path is used.  Currently there is only support for bash-2 available.
-# If other shells also have problems we have to add more code here.
