#   conditional expressions are applied to files.  Here is where
Alain Reguera Delgado e54180
#   centos-art.sh script answers questions like: is the file a regular
Alain Reguera Delgado e54180
#   file or a directory?  Or, is it a symbolic link? Or even, does it
Alain Reguera Delgado e54180
#   have execution rights, etc.  If the verification fails somehow at
Alain Reguera Delgado e54180
#   any point, an error message is output and centos-art.sh script
Alain Reguera Delgado e54180
#   finishes its execution.
