# N.B. It may be a surprise that the derivation-specific variables are exported,

# since this is just sourced by the wrapped binaries---the end consumers. This
|
|
# is because one wrapper binary may invoke another (e.g. cc invoking ld). In
|
|
# that case, it is cheaper/better to not repeat this step and let the forked
|
|
# wrapped binary just inherit the work of the forker's wrapper script.
