* tamam bu onemli, biraz dikkat lutfen

- package context'i archive'in calismasi icin gerekli degil (source info)
  - archive ornegin package class'inin implementation'i icin kullaniliyor
    constructor'a a bakin
  - source adi vs. gibi seyleri bilmesi gereken module, build islemi
    sirasinda build module'u, diger turlu "batteries included" bir archive
    module'u degil, sadece source'lari acabilen bir archive module'u yazmis
    olurduk... ayni zamanda bu biraz sorumluluklarin karistirilmasi oluyor
    module'ler arasinda, bundan kacinmaya calisirsak iyi olur. fetcher'da da
    benzer bir hata olabilir, sadece spec'teki source archive'larini
    indirebiliyorsa, yanlis yazilmis demektir.
  - ayni zamanda dikkat ederseniz, sol kulagi sag elle tutmaya benziyor
    anlattigim tur karisikliklar
  - gereken is bitmis degil. package module'unun gerektirdigi fonksiyonlara
    bakiniz. sadece bazi dosyalari cikarmak, yeni arsiv olusturmak gibi
    fonksiyonlar istemekte.
  - package module'u install operasyonu icin kullanildigi icin onemli
  - tabii gene ayni archive module'unu binary package'lari build ederken de
    kullanabilmeliyiz vs. vs.
