1. A kit-of-parts for assembling to form a linear cutting charge, comprising a plurality of elongate planar members, means for connecting said planar members to form a box-like structure, a liner and means for locating said liner within said box-like structure to provide a space on one side of the liner for receiving an explosive material and a stand-off space on the other side of the liner, said locating means comprising rib means extending inwardly of the assembled box-like structure on opposite sides thereof. 2. A kit-of-parts according to claim 1, wherein said elongate planar members comprise strips of metal, wood or plastics material. 3. A kit-of-parts according to claim 1, wherin said connecting means comprise angle pieces formed integrally with a side margin of at least some of said planar members and adapted to engage an adjacent side margin of an adjacent planar member when forming said box-like structure. 4. A kit-of-parts according to claim 1, wherein said rib means extend inwardly of the box-like structure at an angle to one another. 5. A kit-of-parts according to claim 4, wherein said rib means are arranged at right angles to another. 6. A kit-of-parts according to claim 1, wherein said rib means comprise slots adapted to receive the side margins of an elongate angle-section liner. 7. A kit-of-parts according to claim 6, wherein said rib means comprise slots of different width for receiving elongate angle-section liners of different thickness. 8. A kit-of-parts according to claim 1, wherein said liner comprises an elongate angle-section element or a hollow tubular element. 9. A kit-of-parts according to claim 8, wherein said liner comprises an elongate right-angle-section element. 10. A kit-of-parts according to claim 8, wherein said liner comprises a hollow tubular element of round or square cross-section. 11. A kit-of-parts according to claim 1, wherein said locating means each comprise means for connecting two said planar members edge-to-edge. 12. A kit-of-parts according to claim 11, wherein said connecting means comprise a pair of opposed slots for receiving adjacent side margins of said two planar members. 13. A kit-of-parts according to claim 11, wherein each said locating means is substantially in the form of a letter K in cross-section. 14. A kit-of-parts according to claim 1, wherein at least one of said planar members comprises at least one integral hinge extending along the length thereof and providing said connecting means. 15. A kit-of-parts according to claim 14, wherein said integral hinge is provided by a groove or opposed grooves in said planar member which locally reduces the thickness of the planar member. 16. A kit-of-parts according to claim 14, wherein said planar member has a plurality of parallel integral hinges extending along the length thereof. 17. A kit-of-parts according to claim 16, wherein said planar member has a substantially non-elastic film or foil on one of both surfaces thereof which prevents the planar member folding about any of said integral hinges until the film or foil has been slit along a said integral hinge. 18. A kit-of-parts according to claim 1, comprising closure means for closing the ends of the assembled box-like structure. 19. A kit-of-parts according to claim 18, wherein said closure means comprise end caps. 20. A kit-of-parts according to claim 19, wherein each said end cap comprises peripheral grooves for receiving end margins of said planar members. 21. A kit-of-parts according to claim 19, wherein said end caps comprise plug portions for sealing the ends of a said tubular liner. 22. A kit-of-parts according to claim 1, comprising magnetic means for attaching the assembled linear cutting charge to a ferrous target. 23. A kit-of-parts according to claim 22, wherein said magnetic means comprises a strap having a permanent magnet at each end thereof, whereby the strap can be extended over the assembled linear cutting charge and the magnets attached to the target on either side of the linear cutting charge. 24. A kit-of-parts according to claim 23, wherein said strap is elastically resilient. 25. A kit-of-parts according to claim 23, wherein said strap is attachable to a top wall of the assembled box-like structure. 26. A kit-of-parts according to claim 1, wherein said connecting mean comprise angle pieces adapted to engage adjacent side margins of adjacent planar members when forming said box-like structure. 27. A kit-of-parts according to claim 26, wherein said angle pieces are elongate and are of length to extend over substantially the whole of the length of the planar members. 28. A kit-of-parts according to claim 26, wherein said angle pieces each comprise at least one slot adapted to receive a side margin of a said planar member. 29. A kit-of-parts according to claim 28, wherein said angle pieces each comprise two slots at right-angles to one another and adapted to receive the adjacent side margins of adjacent planar members. 30. A kit-of-parts according to claim 28, wherein said side margins of said planar members are a close fit in said slots. 31. A kit-of-parts according to claim 28, wherein said side margins of said planar members are sealingly securable in said slots. 32. A kit-of-parts according to claim 31, wherein said side margins of said planar members are sealingly securable in said slots by bonding, welding or heat-sealing. 33. A method of forming a linear cutting charge comprising the steps of forming a box-like structure by connecting together a plurality of elongate planar members, the structure being initially open at one side, locating a liner within said box-like structure by rib means extending inwardly of the box-like structure on opposite sides thereof to provide a space on one side of the liner adjacent said open side of the box-like structure and a stand-off space on the other side of the liner, inserting explosive material into said space on said one side of the liner, and thereafter closing said open side of the box-like structure by a said planar member.
