+ * GESEditMode:
+ * @GES_EDIT_MODE_NORMAL: The object is edited the normal way (default).
+ * @GES_EDIT_MODE_RIPPLE: The objects are edited in ripple mode.
+ * The Ripple mode allows you to modify the beginning/end of a clip
+ * and move the neighbours accordingly. This will change the overall
+ * timeline duration. In the case of ripple end, the duration of the
+ * clip being rippled can't be supperior to it max-duration - inpoint
+ * and if it would be the case, nothing wil happen.
+ * @GES_EDIT_MODE_ROLL: The object is edited in roll mode.
+ * The Roll mode allows you to modify the position of an editing point
+ * between two clips without modifying the inpoint of the first clip
+ * nor the out-point of the second clip. This will not change the
+ * overall timeline duration. In the case of ripple end, the duration of the
+ * clip being rolled can't be supperior to it max-duration - inpoint and if
+ * it would be the case, nothing wil happen.
+ * @GES_EDIT_MODE_TRIM: The object is edited in trim mode.
+ * The Trim mode allows you to modify the in-point/out-point of a clip without
+ * modifying it's duration or position in the timeline. A clip being trim
+ * @GES_EDIT_MODE_SLIDE: The object is edited in slide mode.
+ * The Slide mode allows you to modify the position of a clip in a
+ * timeline without modifying it's duration or it's in-point, but will
+ * modify the out-point of the previous clip and in-point of the
+ * following clip so as not to modify the overall timeline duration.
+ * (not implemented yet)
+ *
+ * The various edition modes a clip can be edited with.
+ *
+ *
+ * You can also find more explanation about the behaviour of those modes at:
+ * <ulink url="http://pitivi.org/manual/trimming.html"> trim, ripple and roll</ulink>
+ * and <ulink url="http://pitivi.org/manual/usingclips.html">clip management</ulink>.
