The prefs are called "Startup..." and the cmd line and [declare] flag is called "-lib", so its less consistent than "path".  I chose the name 'import' because its commonly used for loading libs in a number of langauges like Java and Python.

Its a tricky problem because if you have a patch, then you add [declare], [path] or [import] to it it could modify how the existing part of the patch is loaded the next time its opened since the #X declare stuff would then be loaded first.

It seems to me that ideally, [declare], [import], [path], etc. would reload the patch when instantiated the first time so that the patch would always behave the same.  But then the patch would loose its state, so there would have to be a special condition of reloading where it saves the state, reloads, then puts the state info back in.
