Shell script to ease scans from the command-line.
Performs copyright scan on each of the command-line arguments.
If the argument is a directory, scans all of the files contained in the
directory or in subdirectories.
If the argument is a file, scans the file.
The script tries to see through symbolic links to the actual
destination path.
Use the --deep flag to extract and scan files embedded in archives.
Or the --nodeep to turn off deep scanning for subsequent command-line
arguments.
