1. sbopkg downloads a local copy of the repository from www.slackbuilds.org
. This includes all the files required to build the package except for the source.
2. You type "sbopkg -s pkgname" to search for the package you want.
3. If found, it prints the README. Press CTRL-C to exit as continuing will just print the .SlackBuild and .info files. Most if not all of the README files for the packages on slackbuilds.org will have the dependencies that are required after a FULL install of slackware. These should be the only packages you will need to install before the one you really want.
4. If you have forgotten what you have installed from slackbuilds.org, you can type "sbopkg" to in a seperate xterm and select the PACKAGES option. This will list all slackbuilds.org packages installed on the system.
5. Build a Queue in the proper order of all the dependencies avaliable (which they all will be because packages don't get posted to slackbuilds.org unless they can be fully built in at least the most basic form)
6. Save the queue and exit.
7. run "su -c 'sbopkg -i new_queue_name'" to build and install each package in the queue.
IF you did not do a full install of slackware. you can run pkgtool to have a menu based package browser OR just look through the files in /var/adm/packages/. This list all packages installed through slackware's packaging system only.
IF you built a few packages from source with out making a proper slack build, I would hope you know what you have installed already. Check your /usr/local/ file structure for all those things.
IF you used some other method to install a package, good luck.
