The Compile Programs
These are the four programs that are used, and in this order:

CSG CSG stands for Constructive Solid Geometry. It's the map 'type' that Half-Life uses - the format for defining a 3D world. This program is a kind of pre-processor for the BSP tool. It breaks up your map geometry into simpler polygons so that the BSP program can handle it all.

BSP BSP means Binary Space Partition (don't ask), and it basically creates a playable .bsp file from the .map. This .bsp will have no visibility matrix and no lighting (so it'll probably be completely bright). Light and visibility are worked out by the next two programs.

VIS Although this program doesn't have to be run to make your map work, and you may not even notice a difference when you do run it, it is crucial for final compiles. VIS calculates which polygons are visible from every point in the map, so that only polygons visible to the player are drawn at each point. If not run, every polygon will be visible from every point in the map, which can cause major performance loss in big maps, or on slow PCs.

RAD RADiosity is the tool that'll probably take the longest to work. It lights your level, working out texture brightness and colour, and the brightness of the sky, etc. If RAD is not run, the .bsp will either be completely dark or completely bright, and if your map turns out like this, it's probably because of a problem that prevented RAD from running (or you forgot to make it run, or forgot to add lights).
