Django compressor & javascript source map - what's the problem?

Question

JavaScript

Now the project uses compression with yui-compressor.
As far as I understand, he does not know how to make a source map.
The same closure-compiler, for example, can do it, and it seems that it even accepts a bunch of files as input, but it's not clear how to explain it to django compressor...
The point is. A bunch of js files are glued together and compressed into one file.
If it was one file at the input and one at the output, then everything is clear, but it turns out so muddy.
In general, who faced? How did you manage to do it?
