+#@@example tqfp(32,7x7,0.8)
+
+#@@purpose Generate TQFP packages
+#@@desc Generate TQFP packages - a simplified frontend to qf() - 
+#@@desc look up 3..4 data in the datasheet and get a regular TQFP footprint!
+#@@desc NOTE: some of the qf() parameters can be also used.
+
+#@@params:pins,size,pitch,cpad_size
+
+#@@param:pin total number of pins (leads); must be divisible by 4
+#@@param:size a single integer N or NxN or NxNxH; body dimension (width or height of the plastic body) in mm
+#@@param:pitch lead pitch (distance between the centerline of two adjacent leads), in mm; must be one of 0.4, 0.5, 0.65
+
+#@@param:cpad_size width (and height) of the central pad, in mm
+#@@optional:cpad_size
+#@@default:cpad_size empty, there's no central pad
