= Ferret



Ferret is a copy-detection tool, locating duplicate text or code in 

multiple text documents or source files.  Ferret is designed to  

detect copying ( _collusion_ ) within a given set of files.



This version is a Scheme implementation of Ferret. Two versions are given: for

practical use, the Chez Scheme version is preferable because of its execution

speed.

== Chez Scheme Implementation



This version is designed for Chez Scheme.



----

> scheme.exe --libdirs . --program .\chezferret.ss

Usage: chezferret

          dirname                       to compare all files in given directory

       -g dirname                       use subdirectory names to group files

       -x filename1 filename2 [outfile] to output an XML comparison of given filenames

----



== R7RS Implementation



This version requires an R7RS implementation of Scheme such as Gauche.



Run as:



----

> gosh -I. schemeferret.sps

Usage: schemeferret

          dirname                       to compare all files in given directory

       -g dirname                       use subdirectory names to group files
