This manual is incomplete: No attempt is made to explain basic file concepts in a way suitable for novices. Thus, if you are interested, please get involved in improving this manual. The entire free software community will benefit.
This manual was originally derived from the Unix man pages in the distribution, which were written by Ben Asselstine. What you are reading now is the authoritative documentation for the fileschanged program. The man pages will be maintained but will not be as valuable of a resource as this document is.
