File README.md of Package guam-selfcontained

This is a selfcontained guam package that includes the dependencies of guam.

Use the buildtarball.sh script to generate the tarball.

Please note buildtarball.sh requires the guam build dependencies locally available (for a local build),
and if your local OTP version is too recent it won't currently work (works on fc34 but not on fc35), so
use something like toolbox on fedora.
