// Module: dovetail()
|

|

// Usage:
|

// dovetail(gender, l|length, w|width, slide, [slope|angle], [taper|back_width], [chamfer], [r|radius], [round], [$slop])
|
||||
// dovetail(gender, w|width, h|height, slide, [slope|angle], [taper|back_width], [chamfer], [r|radius], [round], [$slop])
|

//
|
||||
// Description:
|
||||
// Produces a possibly tapered dovetail joint shape to attach to or subtract from two parts you wish to join together.

// Example: With a long joint like this, a taper makes the joint easy to assemble. It will go together easily and wedge tightly if you get the tolerances right. Specifying the taper with `back_width` may be easier than using a taper angle. Note that "length" refers to the amount the joint projects from its base, which is a little counter-intuitive when the joint has a very long slide like these sliding dovetails.
