% By Jean Orloff
% Comments & suggestions by e-mail: ORLOFF@surya11.cern.ch
% No modification of this file allowed if not e-sent to me.
%
% A simple way to measure the size of encapsulated postscript figures
% from inside TeX, and to use it for automatically formatting texts
% with inserted figures. Works both under Plain TeX-based macros
% (Phyzzx, Harvmac, Psizzl, ...) and LaTeX environment.
% Provides exactly the same result on any PostScript printer provided
% the single instruction \psfor... is changed to fit the needs of the
% particular dvi->ps translator used.
% History:
% 1.31: adds \psforDVIALW(?)
% 1.30: adds \splitfile & \joinfiles for multi-file management
% 1.24: fix error handling & add \psonlyboxes
% 1.23: adds \putsp@ce for OzTeX fix
% 1.22: makes \drawingBox \global for use in Phyzzx
% 1.21: accepts %%BoundingBox: (atend)
% 1.20: tries to add \psfordvitps for the TeXPS package.
% 1.10: adds \psforoztex, error handling...
