# cli_checkFiles.sh -- This function standardizes the way file

# conditional expressions are applied inside centos-art.sh script.

# Here is where we answer questions like: is the file a regular file

# or a directory?  or, is it a symbolic link? or even, does it have

# execution rights, etc.  If the verification fails somehow at any

# point, an error message is output and centos-art.sh script finishes

# its execution.

    # files based on context must be available.

    # questions like "Is this file under version control?" or "Is this

    # file under the working copy directory structure?".
