[Baypiggies] Unlinking symlinks

[Christopher Lee-Messer]

Perhaps this would be useful if you absolutely want to do a restore.

import os

def safe_unlink(filepath):
    """
    remove symlink given by string filepath
    check that is really a symbolic link not a regular file or directory
    """
    if os.path.islink(filepath):
        os.remove(filepath)
        return True
    else:
        return False
