[LSC] Call for Votes: File Format Restrictions for Official Parts

[Michael Heidemann]

There were several discussion last year about this issue:
http://news.lugnet.com/cad/dev/org/ldraw/?n=4005
http://news.lugnet.com/cad/?n=14510
http://news.lugnet.com/cad/dev/?n=10694

I hope I have also read all carefully. I also wasn't aware that all 
files in the library are already uses DOS line termination.
So it is a good idea to bring this into a specification.

Two questions remains to me.
If I have a file with only <LR> or <CR> as line termination that I 
upload to the PT, is the file that can be downloaded from the PT already 
changed to <CR><LF> or not. If not, I think this should be changed.
Does all files in the official library has already : The last two bytes 
of the file must be <CR><LF>?

So if the official library already is according the the specification 
then I agree.

term "last line"
As you know the <CR><LF> is often called 'newline', so if I put CRLF 
into the file I HAVE A NEW LINE.
Only lines with content need to have a CRLF.
That were my thought. So the new sentence is much more clear.
