+#X text 15 44 The vline~ object \, like line~ \, generates linear ramps
+whose levels and timing are determined by messages you send it. The
+messages consist of a target value \, a time interval (zero if not
+supplied) \, and an initial delay (also zero if not supplied.) Ramps
+may start and stop between audio samples \, in which case the output
+is interpolated accordingly.;
+#X text 15 155 Any number of future ramps may be scheduled and vline~
+will remember them and execute them in order. They must be specified
+in increasing order of initial delay however \, since a segment cancels
+all planned segments at any future time.;
