There is one document that introduced this.
http://www.ldraw.org/library/tracker/ref/filetypesfaq/
I found we have different problems to solve:
1) Usage of the tilde '~' for files in the \s folder.
2) Usage of the tilde '~' for files in the \parts folder
3) Is the tilde '~' part of the description or only a flag.
I think as follow:
1) As nearly all files in the \s folder do have a leading '~' we should force
that for files in the s\ folder.
2a) I don't feel that we should make things that complicated.
If we have a shortcut for the complete part (as we have today). It is no problem
to figure out which parts to bring into a new file to get what we want.
The other way would blow up the library.
Just if you are working with MLCad it is not a problem to generate what you
need.
2b) To work with LSynth is really make sense to have the ends visible to find
that. Although also here a global shortcut will have all the user needs. And
again it is easy to identify what you need with MLCad.
But we should be consistent in using or not using the '~' for such parts.
3) As the '~' is used as a flag we should also handle it as that, so if there is
a partfile in the \parts folder that carry the '~' in front of the
partdescription the partdescription is assumed to be without the '~' and so the
first word has to be in the category list or a category has to be mentioned (See
requirement: http://www.ldraw.org/Article398.html).
This has also to be decided for the "_" flag for colored parts!
