# Determine OS Vendor, Release and Update

# bundle up compatible platforms under larger umbrellas that we have

# determinted are compatible enough (e.g. is_ubuntu covers Ubuntu &

# Debian, is_fedora covers RPM-based distros). Higher-level functions

# such as "install_package" further abstract things in better ways.

# ``os_VENDOR`` - vendor name: ``Ubuntu``, ``Fedora``, etc
