Since 'sed' is a requirement for a development-environment, it can also
be used for EOL transformations:
dos2unix: sed -e 's/^M$//' <-- Use ctrl-v ctrl-m to create the ^M
unix2dos: sed -e 's/$/^M/' <-- Use ctrl-v ctrl-m to create the ^M
Unfortunately "\r" is not recognized by sed on all platforms and
neither is \015. Therefore we have to use the raw CR character.
Cheers,

PS To prevent to over-dosizise the EOL's, you can also check whether
there is already a CR by using: sed -e 's/[^^M]$/^M/'
