[wp-hackers] How to tell if a plugin is active?

[Dave]

I don't have any experience with WordPress plugins but I understand that 
the functions in the plugins attach themselves to hooks in the code?

If so, why not simply add a custom hook to the page rather than call the 
function directly? That way the page would function the same whether or 
not the plugin is active.

Regardless, there should be a function to test if a plugin is active, 
but I don't know of one.
