A silly question about packages organization!!!

edit

Inside a package there is initially the two files CMakeList.txt and package.xml and the folder src. From the tutorials, I understood that the scripts belonging to a package should be placed in its scr folder. However, while studying ROS I found many packages that had thier scripts placed in a user created folder called scripts. Taking into account the said, my question is: Why someones creates a new folder called script instead to use the already existing one called scr. Is this a ROS good practices or just a user preference? If it is a good practice, for what I should use the folder script and for what should I use the folder src.

Thanks in advance!
