From Willy: Define a standard for helper parts

[Milan Vančura]

Should the filenames perhaps reflect the fact that these aren't LEGO parts? In other words, even though these are in the parts directory, is there any particular reason that the filenames should be predominantly numbers? Or should we instead include somewhat descriptive filenames?

I think the description should go into Description tag. Filename should be short and easy to add any new one. My experience is that attempts putting some meaning into a filename make a confusion later: unreadable abbreviations used, discussions about adding some new unexpected type of helper in future and so on.

I suggested a scheme h<number>.dat not to mimic official parts (or even worse, to confuse anybody these are official parts), I suggested it because it is simple and working in 2021, 2167, everything in between and even after

Just my explanation. Nothing more.
