agn2txt
If you download the development release package of my tools, you will find a new tool in there from today. I called it agn2txt and it dumps the content of an autogen AGN file to a readable text file. It is a tool that I used which learning more about the autogen file format. I have included it, because I thought it might be useful for others as well.
I have plans to later also add a txt2agn tool that can do the reverse step, so that you can make minor changes to the autogen by editing the TXT file. But I haven't come to that yet, as I first want to do some more experimentation with making autogen from GIS vector data.
