2035 # An explanation of the sed strings:
2036 # -e 's|^\$(prefix)||' matches and eliminates 'prefix' from 'exec_prefix'
2037 # -e 's|/$||' match a trailing forward slash and eliminates it
2038 # -e 's|^[^/]|/|' forces the string to start with a forward slash (*)
2039 # -e 's|/[^/]*|../|g' replaces each occurrence of /<directory> with ../
2041 # (*) Note this pattern overwrites the first character of the string
2042 # with a forward slash if one is not already present. This is not a
2043 # problem because the exact names of the sub-directories concerned is
2044 # unimportant, just the number of them matters.
2046 # The practical upshot of these patterns is like this:
2048 # prefix exec_prefix result
2049 # ------ ----------- ------
2051 # /foo/ /foo/bar ../
2052 # /foo /foo/bar/ ../
2053 # /foo/ /foo/bar/ ../
