If trying to remove a file with 'rm' on the command line gives you the error 'operation not permitted' you might want to take
a look at the containing folder whether its set to protected. If it is not you might want to install the Developer Tools and
unlock it:
/Developer/Tools/SetFile -a l <filename or wildcard>
