command line program to list layers in a DXF/DWG file

Question

I have a CAD file and I'd like to do some scripting with it and was hoping for a little software program that could just give me a list of the layers. I tried (on mac and windows) to get CAD::Drawing from cpan working (perl) to no avail.

Could somebody point me to either a library (more or less any language is fine) or a software program that will allow me to accomplish this. Platform doesn't matter I have access to Linux mac and pc.

Thanks

For standalone applications, the two most common DWG libraries are Teigha and RealDWG. DXF files are text files that can be parsed fairly easily without any special libraries.
