# First argument is version series (as in the download page address at erights.org) and second argument is the full version. Yes, I should improve this.


# TODO:
#   - Determine osdir, machdir, javacmd instead of being hardcoded
#   - Pick curl or wget depending on which is available.
#   - Usage help
#   - Automatically find latest E version
#   - Tell curl/wget about the download site's cert
#   - Run the substitution on rune-template and offer to install it
#   - Pretty progress output
#   - 'Relocate' option which just reruns the path substitutions on an existing e-home
#   - Make source installation optional
#   - Choice of tracelog location and dir perms
