echo >README.Fedora <<EOM
This is a go package for Fedora. It notably differs from the standard
go set of binaries in that it ignores the environmental variables,
except for GOROOT. It uses GOROOT to allow the newly-built 6g to find
newly-built packages for other package imports during the build
process.
