# Go has a number of supplementary tools and packages that are located in
# separate archives or source repositories. Because Go currently forces a
# recompile of all packages whenever the compiler changes, building and
# delivering them within the same build component build process is the best
# option for now.

# This version of Go is not actually packaged; it is only used to bootstrap the
# actual version of the Go that will be packaged.  The long-term plan is
# roughly as follows:
#
# - verify 1.5 produces "correct" result for bootstrapping 1.5 (upstream
#   still uses 1.4 officially)
# - after 1.5 has been available for at least a few builds in the WOS, switch
#   to building Go with system version of Go
# - when SPARC support is integrated into Go upstream, build upstream version
#   using system Go for x86, then build Go for SPARC using upstream version
#   just built for x86 (cross-compilation), package both at the same time
# - after SPARC version has been available for at least a few builds in the
#   WOS, switch to building Go with system version for x86 and SPARC
