- Someone just had a problem on using zed.sty and psfig.sty together. I had
- similar problem. The problem was, psfig could not read size of the picture in
- a Postscript file. This size is normally told using a BoundingBox comment in
- the file.
-
- I started to search a reason for the problem. It turn out, that zed.sty
- defines a macro (or a character, I think) called \empty, which is used to
- typeset the empty set mark. Problem is, LaTeX defines a macro called \empty
- (in lplain.tex, so its kind of build in to TeX), which is defined as
-
- \def\empty{}
-
- Psfig uses the macro to check, whether after %BoundingBox comes numbers for
- the coordinates of the picture, or '(atend)', which means that the real size
- is defined at the end of the file.
-
- Since \empty seems to be part of the TeX, I suggest that zed.sty's \empty is
- renamed, for example to \Empty or \emptyset. I know, that zed.sty is a part
- of the fUZZ package, which is used to check the specification, but Mike
- should have been checked the TeXbook first ;-)
