Source Mapper v0.99c OS/2 and DOS utility to make a useful (human readable) map of your C-style source codes. You can generate a map of a single sourcefile, or you can have SM generate a map of a huge project that consists of many source files. The produced map is espesially useful when you need to document the source(s) of your project. I've also found it helpful when digging into sources written by others.
