Re^2: What is the significance of a package

[pemungkah]

Possibly an interview question - and there's nothing wrong with wanting to be able to answer an interview question - but I do encourage reading up on things like this, and asking a more detailed question if there's confusion; being able to answer the questions, but not really use the concepts, may get you a job, but understanding them well will keep you this one and make it far easier to get the next one ("say, that programmer really gets this stuff").
