Open source is open codes that can be freely downloaded and distributed.
Programs with the open tags are synonymous with your personal freedom to do with the software what you want. There are no owners and nothing is protected by licenses. With open source software you have:
* The freedom to run the program
* The freedom to study the program structure, and to adapt it to your specific needs. Therefore, the open source code is vital
* The freedom to redistribute the program so that you can help others
* The freedom to publish improvements so that all enjoy them. Again, here the open source code is also needed.
