When a git readme says, they are implying that rtp is your(mine) particular runtime path or (?) even some sort of global variable and i should not just slap this into my .vimrc and expect it to "just werk".
I have encountered enigmatic abbreviations and obfuscations of this sort in the linux community many a time, but have only now mustered enough bravery to enter your domain and ask. I do think all of this is a little elitist, but i'm, of course, just a front-end engineer... whoopsie, i mean developer. (jokes on me, please explain the path though)
" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
For me this generalizes: I sort of get it by now that it is common practice to keep certain paths stored as global variables for convenience, but i'm still fairly confused as to what is a "runtime path", how is that different from "adding to PATH". PATH is something that your whole systems knows about, right? Whereas this vim runtime directory is wheresoever you choose to stick your (what?) package manager?
Thanks a ton in advance for clarification on any of these points, i realize all of this is pretty basic.
