New in RPM 2.0 (or previously undocumented):
*** Install
--replacepkgs - will install a package even if it's already in the database
--replacefiles - will install a package even if the files it contains conflict
with others
--force - same as "--replacepkgs --replacefiles"
*** Uninstall
*** Upgrade
*** Query
*** Verify
*** PGP Signatures
RPM now supports optional PGP signatures embedded in RPM packages.
Only 1024 bit keys are supported, and the signature "covers" the
header and archive sections of the package. The "lead", which
makes up the first 96 bytes of every package is not covered by
the signature. This should not be cause for alarm as the lead
is only used by file(1), and by RPM to determine the package type
(either source or binary) and architecture.
*** Spec file (RPM building)
. Summary: ...
A one (short) line description of the package. This field
takes over what Description used to do, but is limited to
a single line. For an interim period, if the Summary is
not defined the description will be used instead.
. Description: ...
An optional mulit-line description of the package.
. Packager: ...
Name and email address of the person who "maintains" the RPM
. URL: ...
A place to put a URL for more info on the package (http://...)
. Serial: ...
This number should be monotonically increasing with each new
release of the package. If present, it will be used by RPM
to define an ordering. If not present RPM tries to determine
the ordering from the Version field.
