Freefile is a clone of the file(1) program that reads files and generates an educated guess about their contents. This version differs from implementations based on Ian Darwin's code in three ways: the source code is smaller, "file -z" can decode the contents of bzip2 files (and gzip files, which both implentations can handle), and it is GPL'ed. Freefile was originally written to resolve copyright issues about Ian Darwin's version, some of which still remain.
