Remark FMi (91/01/16): Unfortunately the AMS decided to reset the version number of
the files after they got installed on some servers.
Most of the test versions had version numbers like v1.0m
but the new distribution has now v1.0a. If you got the 2 A
2 M2 S-LATEX package with version numbers higher than, say, v1.0c then you got
probably a pre-release version.
This can also be determined by looking at the date recorded
in the files.
