A key note on apt

Just felt like writing something useful…I’ve been checking out on packaging for a while now,and came up with some couple of interesting(and not so interesting details)

1. apt-get and apt-cache are exclusively for .deb packages.But now they have come up with apt-rpm too for rpm packages.

2.The sources.list file present @ /etc/apt can be modified .What do we gain? In case you find a great repositary for .deb packages and others,then you can list them out there.I’ll just paste the contents down here..
