Class
Constants
The builder shells-out to run various commands after changing the directory. This means multiple installations cannot be allowed to build extensions in parallel as they may change each other’s directories leading to broken extensions or failed installations.

end
Creates a new extension builder for spec
. If the spec
does not yet have build arguments, saved, set build_args
which is an ARGV-style array.
