Nodes of different colours represent the following:
Solid arrows point from a submodule to the (sub)module which it is
descended from. Dashed arrows point from a module or program unit to
modules which it uses.
Returns .PSPIC macro to add image in Encapsulated PostScript (EPS)
format. Argument align must be either L (left), R (right), or
C (center). If not passed, the image will be centered.
The arguments width and height give the desired width and height
of the image. If neither a width nor a height argument is specified,
the image’s natural width (as given in the file’s bounding box) or
the current line length is used as the width, whatever is smaller.
Nodes of different colours represent the following:
Solid arrows point from a procedure to one which it calls. Dashed
arrows point from an interface to procedures which implement that interface.
This could include the module procedures in a generic interface or the
implementation in a submodule of an interface in a parent module.
