NaviSoft's choice of Tcl illustrates all the elements that need to come together before an open-source software package can be adopted. The Tcl interpreter was free, open-source, and explicitly designed to be included in larger programs. Moreover, the authors produced documents with titles like "How to compile the Tcl interpreter into your C program". The interpreter as released by John Ousterhout wasn't thread-safe, but it was simple enough that Jim and Doug could find the parts of Tcl that weren't thread-safe and make them thread-safe. We can conclude from this example that the open-source programs with the most impact will be those that are the easiest to understand and adopt, not those with the most features.
