Description of problem:

Section 3.2.1.1. Checking That the Package Is Installed
of the RPM documentation
http://docs.fedoraproject.org/drafts/rpm-guide-en/ch03s02.html states that the
'' rpm -q '' command must be given a package name rather than an rpm package
file.  At some point this may have been the case, but thankfully this isn't the
case anymore (CentOS5 rpm version: rpm-4.4.2-47.el5)

Version-Release number of selected component (if applicable):


How reproducible:
Every time.

Steps to Reproduce:
1.  Get an RPM file
2.  rpm -q some-rpm.rpm
3.  profit!
  
Actual results:
True statements as to whether or not some-rpm is installed.
And profit (cause the documented "rpm isn't smart enough to open the rpm file
and get the package name" behavior is seriously suboptimal especially since the
package name and the rpm file aren't required to be related).

Expected results:
Documentation says that rpm will halt and catch fire, or fail to work, neither
of which is desirable.

Additional info:

Here's the original text:
"Use the rpm –q command to quickly verify a package has been installed. To
verify, you need to use the name of the installed package, not the name of the
RPM file."

And here's some new text:
"use the rpm -q command to quickly verify a package has been installed.  To
verify, you can either use the name of the installed package, a partial package
name, or the path to an rpm file."
