Well, MSConsole project has started. MSConsole is about converting axl project files in valid mapserver configuration files, ready for use. In this way you can configure your mapserver applications with the easiness of use of the well-known, industry standard ESRI tools, save the project in AXL format and then convert it in a ready to use mapserver file.
MSConsole is written in Java and should run an any operating system, but the primary target will be *NIX because that’s the platform it is being developed on.
The first release will probably be available in two weeks’ time, but I count on having code on sourceforge CVS earlier.
