I personally find very painful to be forced to call whirr script using its whole path. I'd prefer to add whirr script to my $PATH env variable so that I can call whirr from anywhere. I've modified the whirr script according to this purpose.
I've created two version of the modified script:
- one that uses the readlink command
- one that doesn't used the former command.
I only tested under Ubuntu 11.04 so I've no idea whether or not the readlink command is available on other distros. So please test and comment.
