how to find the list of all packages present in a directory

Hi

I'm in a directory named /tmp/mq7

i need to upgrade the mq version from 6 to 7 but im not sure where is the package located ?

which command in solaris will show me the list of all the packages present in the directory /tmp/mq7 ?

my box is running with solaris version 10.

 
find /tmp/mq7 -type f -name "*pstream"

Other thing is, if you are already in that directory, you could also check,
pkgadd * or pkgadd, it should directly prompt you to select which pkg you want to install, if there is a pkg within that directory.
