CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims priority to U.S. provisional patent application No. 60/378,635 filed May 7, 2002, the entire content of which is incorporated herein by this reference. FIELD OF THE INVENTION [0002] The present invention generally relates to wound treatment and systems and methods of preparing a wound dressing. More particularly, it relates to a wound treatment including a dressing adapted to match the wound site. BACKGROUND OF THE INVENTION [0003] Currently, the common method of wound treatment is to cover the wound with a wound dressing. The wound dressing is manufactured as a precut sheet of multi-layer material of various shapes and sizes. The wound dressing is applied to cover the wound and a portion of the surrounding healthy skin. Sometimes the wound dressing is cut to reduce the size and to better fit the wound size and shape. This reduces the amount of healthy skin covered by the dressing. [0004] A typical wound commonly has two or more regions or areas, including necrotic, sloughy, bacteria colonized, granulating, epitheliazing, bleeding, exudating, and drying. An exemplary wound 10 has a granulating area 12 having heavy exudates and an epitheliazing area 14 having low exudates, which are surrounded by healthy skin tissue 16 (see FIG. 1). The wound 10 and its areas 12, 14 are usually of irregular shapes. The areas 12 and 14 of the wound 10 typically differ from each other by healing stage, depth, contamination, infection, and tissue stress due to patient body movement. Consequently, covering the whole wound area and surrounding healthy skin with the same dressing type may create adverse conditions for certain areas of the wound or the surrounding skin, which may increase the healing time or even cause adverse effects such as secondary dermatitis. [0005] Accordingly, there is a need in the art for a method for wound care that provides the optimal conditions for wound healing by matching the size, shape, and material properties of a wound dressing to the wound area. There is a further need for a system to produce such a wound dressing. SUMMARY OF THE INVENTION [0006] According to one embodiment of the invention, a method of treating a wound using a customized dressing is provided. In the method, at least one wound characteristic is evaluated. A treatment need as a function of the at least one wound characteristic is determined. A dressing having a dressing characteristic responsive to the treatment need is fabricated and applied to the wound. A dressing for use therewith and an apparatus and system for fabricating the dressing are provided. [0007] While multiple embodiments are disclosed, still other embodiments of the present invention will become apparent to those skilled in the art from the following detailed description, which shows and describes illustrative embodiments of the invention. As will be realized, the invention is capable of modifications in various obvious aspects, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are to be regarded as illustrative in nature and not restrictive. BRIEF DESCRIPTION OF THE DRAWINGS [0008] The accompanying drawings, which are somewhat schematic in many instances and are incorporated in and form a part of this specification, illustrate exemplary embodiments of the invention and, together with the description, serve to explain the principles of the invention. [0009] FIG. 1 is an isometric view of a typical wound. [0010] FIG. 2 is an isometric view of a wound covered with a wound dressing according to one embodiment of the present invention. [0011] FIG. 3 is a sectional view of the wound dressing taken along the line 3-3 in FIG. 2. [0012] FIG. 4 is a flow chart showing a method of treating a wound using a wound dressing according to one embodiment of the present invention. [0013] FIG. 5 is a schematic view of a wound dressing fabrication system according to one embodiment of the present invention. [0014] FIGS. 6A and 6B are flow charts illustrating the steps performed by the processor of the system shown in FIG. 5, according to various embodiments of the invention. [0015] FIG. 7 is schematic view of a portion of a wound dressing fabrication device. [0016] FIG. 8 is an isometric view of a device for fabricating a wound dressing according to one embodiment of the present invention. [0017] FIG. 9 is a partial isometric view the device of FIG. 8. DESCRIPTION OF THE INVENTION [0018] A wound 20 is covered by an adapted or customized wound dressing 22 (see FIG. 2). The wound dressing 22 may include two or more regions or layers. Each region or layer is customized to match a size and shape of the wound (see FIGS. 2 and 3). It is further customized to address one or more wound healing needs. In one embodiment, the wound dressing 22 includes a first region 26, second region 28, and a backing film 30 (see FIG. 3). The first region 26 of the wound dressing 22 is located generally near a center of the wound dressing 22 and is sized and shaped to generally match or engage the first (e.g., granulating) area 12 of the wound 20. The second region 28 of the wound dressing 22 surrounds the first region 26 and is sized and shaped to generally match or engage the second (e.g., epitheliazing) area 14 of the wound 20.
