#Script untuk otomatisasi pembuatan repository lokal
#Pembuat: Mochamad Taufan Rezzafri (taufan.rezzafri@yahoo.co.id)
#Lisensi : GPL
#Terdiri dari 5 bagian yaitu :
# 1. Eksekusi apt-move -d `lsb_release -sc` update
# 2. Pembuatan Directory tree yang belum dibuat secara otomatis pada langkah pertama
# 3. Pembuatan file Release
# 4. Pembuatan File info (berguna bila repository ditempatkan pada media CD/DVD)
# 5. Memberikan "tandatangan" pada file Release dan pembuatan file Public.key
