+// huffware script: "party culiar", by fred huffhines
+//
+// this is yet another particle system script, based on ideas seen
+// in several scripts by various authors and assisted by the lsl wiki.
+// it has the useful characteristic of being able to load its parameters
+// from a notecard, thus making script modifications for the particle
+// system unnecessary.
+// on initial rez, if a notecard exists, then it is read for particle
+// system parameters named similarly to the variables below (see the
+// particle archetype notecard for more details). if the object is
+// rezzed with an existing particle system already read from a notecard
+// that's still present, it will keep playing that particle system.
+// if a notecard is added or changed, then the particle variables are
+// read again.
