14 The package manager wouldn't need any more knowledge of bash syntax than
15 it currently has. All of the implementation details would be the same as
16 they are now. The only difference would be that the regex would return a
17 match in _more_ cases. I think that this would be preferable to Brian's
18 suggestion to make the regex fail to match an empty EAPI setting (which
19 would return a match in _fewer_ cases).
