this is a awk based code generator. Very primitive at the moment, but it was sufficient to generate info level 6 of the add printer driver for spoolss It has two capabilities: 1) generate the header and C code for parsing a structure, given a *.struct file that describes the structure. Evetually I hope to make *.struct compatible with MIDL. 2) it provides a harness that can read a binary data file from prs_dump() which contains real data from a client and display the parse of it from the output of the awk parser. This allows you to "play" with the structure definition until it comes out right, it takes just a few mimutes of playing with the .struct file to work out the right layout. all this is very primitive right now. I hope next to completely replace the spoolss parser with a single .struct file that describes all the structures, and auto-generates working code. That will require quite a bit more work.

renamed the harness program to vluke (for "virtual luke") added a couple of sample .prs files
