For reverence, the new method to get the version according to the docs
is: http://www.erlang.org/doc/system_principles/versions.html

    In an OTP source code tree, the OTP version can be read from the text
    file <OTP source root>/OTP_VERSION. The absolute path to the file can be
    constructed by calling filename:join([code:root_dir(), "OTP_VERSION"]).

    In an installed OTP development system, the OTP version can be read from
    the text file <OTP installation root>/releases/<OTP release
    number>/OTP_VERSION. The absolute path to the file can by constructed by
    calling filename:join([code:root_dir(), "releases",
    erlang:system_info(otp_release), "OTP_VERSION"]).

Do note that the version number can be followed by '**', meaning it was
patched with otp_patch_apply.
