-help              # Prints out the command usage

-d                 # User specified values and return values are in database units.

                   # Default: All values are in user units, in microns. (bool, optional)

-step <step>       # Specifies step size if output format is rect, required to convert

                   # non-orthogonal shapes into series of rectangles. Default: minwidth

                   # value of first routing layer (coord, optional).

-output {polygon rect hrect area}

                   # Specifies the output format. (rect = vertical rectangles,

                   # hrect = horizontal rectangles), area = total area of final shape

                   # default: rect (enum, optional)

<shapeList>        # polygon or rect or list of polygon and rect. polygon:

                   # {{x y} {x y} {x y} ... }; rect: {x1 y1 x2 y2} (list, required)

AND <shapeList>    # binary operator: intersection of list of shapes

ANDNOT <shapeList> # binary operator: initial list of shapes minus second list of shapes

OR <shapeList>     # binary operator: union of list of shapes

XOR <shapeList>    # binary operator: union of list of shapes minus AND of the list of shapes

                   # (string, optional)

INSIDE <shapelist> # binary operator: initial shapes that are inside (including touching) 

                   # of one of the shapes from the second list

OUTSIDE <shapelist># binary operator: initial shapes that are outside (including touching)

                   # of the shapes from the second list

ENCLOSE <shapelist># binary operator: initial shapes that completely enclose at least one shape from the second list

STRADDLE <shapelist>

                   # binary operator: initial shapes that are partially inside and partially outside

                   # at least one shape from the second list

MOVE {<dx> <dy>}   # unary operator : move the list of shapes by {<dx> <dy>}

BBOX               # unary operator : computes the bounding box of list of shapes

                   # (string, optional)

HOLES              # unary operator : returns list of new shapes that fill holes in the original list of shapes

NOHOLES            # unary operator : returns list of new shapes that include filled holes in the original list of shapes

                   # (same as dbShape $shapeList HOLES OR $shapeList)

SIZE  <value>      # unary operator : increase the size of list of shapes by <value>

SIZEX <value>      # unary operator : increase the size of the list of shapes in the

                   # X-direction by <value>

SIZEY <value>      # unary operator : increase the size of the list of shapes in the

                   # Y-direction by <value>
