Apt-get build-dep?

[Devsforev]

Hey everyone. I've noticed that when I run "apt-get build-dep" with files that I have installed using apt-get, it sugguests I install a lot more libraries and dependencies. I've used it a couple times such as when I have trouble getting a program to work (used it for wmweather+ a little while ago). But is there any advantage to using that on all my programs? More importantly, should I do that for all my programs? Thanks a lot.

build-dep if for getting the dependencies to build a package from source.
so when you use it, you get all the developement header files and what not that go with the libraries the package uses. Stuff only needed to compile the package. That stuff doesn't help the way the binary package runs.
