From what I understand, the text file found at:

ftp://ffs-atlanta.external.hp.com/export/patches/mpe-ix_obs_patch_list

is a nice list of MPE patches which have been obsoleted, with the name
of the replacement patch(es) included.  This seems pretty
straight-forward enough (and is kinda cool to know).

Can anyone tell me though, what the numbers in column 1 (& sometimes 2)
mean?
Are they (should they be) significant to me?

Thanks!
