- Replaced md5(sum) with openssl. Less platform dependent because the tool is same across platforms
- Preparation for name-safe file operations.
- Sanity against sed
- Correctly encoded url (hopefully)
- getopts replacing fail hackjob with while and shift
- support for login (provided with openssl)
