Is anyone else confused?

IBM: How am I supposed to tell what version of client software is which?

Example 1:
----------
hpux.v2r1m6.IP20996.image has been modified 3 times during the past 2 months
hpux.v2r1m6.IP20996.image has been modified 3 times during the past 2 months
on index.storsys.ibm.com.

-rw-rw-r--   1 snow     ADSMLVL2 11304960 Dec 20 13:14 hpux.v2r1m6.IP20996.image
-rw-rw-r--   1 snow     ADSMLVL2 11304960 Feb  7 21:21 hpux.v2r1m6.IP20996.image
-rw-rw-r--   1 snow     ADSMLVL2 11304960 Feb  7 21:21 hpux.v2r1m6.IP20996.image
-rw-rw-r--   1 snow     ADSMLVL2 11304960 Jan 16 19:25 hpux.v2r1m6.IP20996.image
-rw-rw-r--   1 snow     ADSMLVL2 11304960 Jan 16 19:25 hpux.v2r1m6.IP20996.image
Which one of these is 2.1.0.6?
Which one of these is 2.1.0.6?
Which one is 2.1.0.6G?
What is the other one?

Example 2:
----------
sol25.v2r1m6.IP20999.pkg.Z has been modified twice.
sol25.v2r1m6.IP20999.pkg.Z has been modified twice.

-rw-rw-r--   1 snow    ADSMLVL2 15101349 Feb 25 22:01 sol25.v2r1m6.IP20999.pkg.Z
-rw-rw-r--   1 snow    ADSMLVL2 15102002 Jan  2 22:18 sol25.v2r1m6.IP20999.pkg.Z
-rw-rw-r--   1 snow    ADSMLVL2 15102002 Jan  2 22:18 sol25.v2r1m6.IP20999.pkg.Z

How is one to tell if this is 2.1.0.6 or really 2.1.0.6G?

IBM: Can you please improve the way you identify software, both on the ftp
sites and as reported by the software itself ??
