RPM = Linux's Redhat Package Manager (synonymous with AIX's installp command).

Incantations of rpm are

    rpm -q -a                            to query
    rpm -qi openssl-0.9.6b-3             to see info on the package, including when
                                         it was installed, version, and more text.
    rpm -ql openssl-0.9.6b-3             to show the files belonging to this package.
    rpm -qf /opt/freeware/bin/openssl    to show which package owns this file
    rpm -e -vv --test openssl-0.9.6b-3   to show what it would do if you "erased"
                                         the openssl-0.9.6b-3 package.
    rpm -e openssl-0.9.6b-3              to actually delete/erase a package

On 5-27-2003, rpm -q -a shows I have these 5 RPM packages installed (with my notes)
    AIX-rpm-4.3.3.75-1         (The rpm command.  See ~/aixnotes/ssh.install.notes)
    openssl-0.9.6b-3           (Installed on 6-7-2002.  See ~/aixnotes/ssh.install.notes)
    gettext-0.10.39-2          (Needed by AIX-rpm-4.3.3.75-1)
    glib-1.2.10-2              (Part of netscape.  See ~/aixnotes/netscape)
    gtk+-1.2.10-3              (Part of netscape.  See ~/aixnotes/netscape)

but I erased the OpenSSL package so that I could start anew.
