It seems silly for us to spend time and effort composing an explanation of packages, and sample code, when both are provided in Perl's documentation, here: perlobj, where it says, "A package is simply a namespace containing variables and subroutines."
perlmod is also useful.
Now if your question was, "I've read perlobj and perlmod, but am having trouble understanding xyz, then it wouldn't seem like duplicated effort.
So go ahead and look them over. Let us know what questions they don't settle.
