simple line with two hyperlinks at end in postscript and pdfmaker
 

Its superconfusing for me, since pdfmaker and postscript are doing same, but in practice coding style is quite different.

I know how to make a line with 2 circles at its end, with moveto and lineto and arc command in Postscript language, however, apparently I have to move to pdfmark due to hyperlinks, pdfmark manual is super un-understandable, and there is no other reference(book/online tutorial).

So, I would be appreciate, if one could generate such thing (as my figure shows) with a little description.

This picture can make it clear
