4236 # An explanation of the sed strings:
4237 #  -e 's|^\$(prefix)||'   matches and eliminates 'prefix' from 'exec_prefix'
4238 #  -e 's|/$||'            match a trailing forward slash and eliminates it
4239 #  -e 's|^[^/]|/|'        forces the string to start with a forward slash (*)
4240 #  -e 's|/[^/]*|../|g'    replaces each occurance of /<directory> with ../
4241 #
4242 # (*) Note this pattern overwrites the first character of the string
4243 # with a forward slash if one is not already present.  This is not a
4244 # problem because the exact names of the sub-directories concerned is
4245 # unimportant, just the number of them matters.
4246 #
4247 # The practical upshot of these patterns is like this:
4248 #
4249 #  prefix     exec_prefix        result
4250 #  ------     -----------        ------
