Before starting I would like to emphasize that I am not an experienced packer but with practice I would like to become one, so one could say that is my personal dojo.

Well, I recently created a small repository that contains applications that I use daily and for some circumstance, there are no official repositories, SlackBuild.org, for some reason have not been updated for some time, etc.

Maybe I'm not following the Slackware philosophy but I try to update it very often to also have the most recent versions also I try to include new applications, so I suggest you keep abreast.
Any comments, suggestions or "lesson of the day" are always welcomed!

Best regards and enjoy!
P.S. Even I have pending replace the slack-required file by dep file, I will when I can.
