Work on it stopped some time ago (when I went back to working Seismic).
As such it is totally unsupported. It is provided here because occasionally someone asks for it, and it is easier for me to point them to the Web site than dig through my old files.
I will probably answer questions related to it, but I am not very interested in making changes to it or rewriting it (unless someone wants to give me lots of money of course).
The download is quite big (~4MB) due to it including the VB4 runtime files.
There is a text file included that provides basic instructions.
The LAS Format description can be found at the CWLS
