-	Creates a directory called "common-files" and moves the common file there and 
-	then creates symlinks to that file in the current directory.
+[>DESCRIPTION]
 
+.B clink
+compares the sha256 and md5 hashes of each regular file found under the 
+paths passed as arguments, so as to identify duplicate files and move them to 
+<parent_dir>\fB/common-files\fP (this directory will be created as needed, 
+possibly with a numerical suffix to avoid overwriting an existing path). 
+Symlinks are placed in the original directories pointing to the new location.
