Lines at the beginning of PostScript files reading
	PS-ADOBE-x.y
do not refer to PostScript versions -- they refer to the version
number of the Adobe Document Structuring Conventions.  So a PostScript
file starting with the line
	PS-ADOBE-2.0

claims to be conformant with version 2.0 of the Document
Structuring Conventions.  Whether it actually is compliant,
is of course, a completely different issue.
