Conclusion

SPEFO is considered by its users to be a very powerful program providing the stellar astronomer with the all tools necessary for efficient stellar spectra investigation from the raw data acquisition and its basic reduction up to the final session protocol and plot, that may be directly included into the published article. It sure contains a lot of bugs that will be exterminated during the time, has some awkward features and not well-polished user interface, but it might be a good choice for someone wishing to do his work on a small MSDOS-based PC (e.g the notebook) as the one of SPEFO's outstanding feature is its compactness and small code with minimal HW demands.
