    `input \ps_filename \
      [.xcm. .ycm. \
        [.xmag. .ymag. \
          [.rot_deg.]]]'
Input the named PostScript file directly into the Gri output PostScript file. (If the filename has punctuation, insert it in double quotes, e.g. ``input "../thefile"`'.) If no options are specified, the file is input at normal scale, with normal margins. (Aside to PostScript programmers: the named file is sandwiched between ``gsave`' and ``grestore`' commands.) If ``.xcm.`' and ``.ycm.`' are specified, then the origin is moved to the named location first. If, in addition, ``.xmag.`' and ``.ymag.`' are specified, then these are used as scale factors after translation. Finally, if ``.rot_deg.`' is specified in addition, then the indicated counterclockwise rotation is applied after translation and scaling. Hint: if the results look wrong, the first thing to do is to think carefully about the order of the (translation, scaling, rotation) operations.
