getting variables to use in plugin's / external php pages

[kh99]

I don't think you need the global statement at global_bootstrap_init_start, but I think what you want is $vbulletin->options['keywords']; (I don't know why they chose to make it "vboptions" in the templates). If you're including (or requiring) your external file you shouldn't have to do anything special, you could access $vbulletin->options or set another variable (but maybe you know that part already).
