parse the '+CONTENTS' file

[Zane C.B.]

When passing the '+CONTENTS' file for a installed package, what do
lines matching /^\@cwd/ mean past the first one? I know the first one
is the base, but what the ones after that for?

On a similar note, what are the lines matching /^@ignore/ for?

I am seeing both in '+CONTENTS' file for 'py25-numeric-24.2'.

@cwd .
@ignore
