+%
+% ======================================================================
+% Modification History:
+%
+%  9 Oct 1990   JDS	used more robust bbox reading code from Tom Rokicki
+% 29 Mar 1991   JDS	implemented rotation= option
+% 25 Jun 1991   RR	if bb specified on cmd line don't check
+%			for .ps file.
+%  3 Jul 1991	JDS	check if file already read in once
+%  4 Sep 1991	JDS	fixed incorrect computation of rotated
+%			bounding box
+% 25 Sep 1991	GVR	expanded synopsis of \psfig
+% 14 Oct 1991	JDS	\fbox code from LaTeX so \psdraft works with TeX
+%			changed \typeout to \ps@typeout
+% 17 Oct 1991	JDS	added \psscalefirst and \psrotatefirst
+% 23 Jun 1993   KHC     ``doclip'' must appear before ``rotate''
+% 27 Oct 1993   TJD	removed printing of filename to avoid 
+%			underscore problems. changed \frame to \fbox.
+%			Added OzTeX support from BG. Added new
+%			figure search path code from GT.
+%
+% ======================================================================
+%
+% Command synopsis:
+%
+% \psdraft	draws an outline box, but doesn't include the figure
+%		in the DVI file.  Useful for previewing.
+%
+% \psfull	includes the figure in the DVI file (default).
+%
+% \psscalefirst width= or height= specifies the size of the figure
+% 		before rotation.
+% \psrotatefirst (default) width= or height= specifies the size of the
+% 		 figure after rotation.  Asymetric figures will
+% 		 appear to shrink.
+%
+% \psfigurepath{dir:dir:...}  sets the path to search for the figure
+%
+% \psfig
+% usage: \psfig{file=, figure=, height=, width=,
+%			bbllx=, bblly=, bburx=, bbury=,
+%			rheight=, rwidth=, clip=, angle=, silent=}
+%
+%	"file" is the filename.  If no path name is specified and the
+%		file is not found in the current directory,
+%		it will be looked for in directory \psfigurepath.
+%	"figure" is a synonym for "file".
+%	By default, the width and height of the figure are taken from
+%		the BoundingBox of the figure.
+%	If "width" is specified, the figure is scaled so that it has
+%		the specified width.  Its height changes proportionately.
+%	If "height" is specified, the figure is scaled so that it has
+%		the specified height.  Its width changes proportionately.
+%	If both "width" and "height" are specified, the figure is scaled
+%		anamorphically.
+%	"bbllx", "bblly", "bburx", and "bbury" control the PostScript
+%		BoundingBox.  If these four values are specified
+%               *before* the "file" option, the PSFIG will not try to
+%               open the PostScript file.
+%	"rheight" and "rwidth" are the reserved height and width
+%		of the figure, i.e., how big TeX actually thinks
+%		the figure is.  They default to "width" and "height".
+%	The "clip" option ensures that no portion of the figure will
+%		appear outside its BoundingBox.  "clip=" is a switch and
+%		takes no value, but the `=' must be present.
+%	The "angle" option specifies the angle of rotation (degrees, ccw).
+%	The "silent" option makes \psfig work silently.
+%
+% ======================================================================
+% check to see if macros already loaded in (maybe some other file says
+% "\input psfig") ...
+\ifx\undefined\psfig\else\endinput\fi
+%
+% from a suggestion by eijkhout@csrd.uiuc.edu to allow
+% loading as a style file. Changed to avoid problems
+% with amstex per suggestion by jbence@math.ucla.edu
