alternative build systems, by installing an appropriate "driver"
program for the build system and specifying its location in the
GOPACKAGESDRIVER environment variable.

The patterns are provided as positional command-line arguments. A
JSON-encoded [DriverRequest] message providing additional information
is written to the driver's standard input. The driver must write a
JSON-encoded [DriverResponse] message to its standard output. (This
message differs from the JSON schema produced by 'go list'.)
