# 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.

#

# - 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

#

# Supplementary packages; these are delivered as source only for now as the

# paths to the compiled packages are written directly into the binaries and

# there's no way (currently) to fix that during the build process.
