Load passes most patterns directly to the underlying build tool.
The default build tool is the go command.
Its supported patterns are described at
https://pkg.go.dev/cmd/go#hdr-Package_lists_and_patterns.
Load may be used in Go projects that use alternative build systems, by
installing an appropriate "driver" program for the build system and
specifying its location in the GOPACKAGESDRIVER environment variable.
For example,
https://github.com/bazelbuild/rules_go/wiki/Editor-and-tool-integration
explains how to use the driver for Bazel.
The driver program is responsible for interpreting patterns in its
preferred notation and reporting information about the packages that
they identify.
(See driverRequest and driverResponse types for the JSON
schema used by the protocol.
Though the protocol is supported, these types are currently unexported;
see #64608 for a proposal to publish them.)
Regardless of driver, all patterns with the prefix "query=", where query is a
non-empty string of letters from [a-z], are reserved and may be
interpreted as query operators.

for details.
Most tools should pass their command-line arguments (after any flags)

uninterpreted to [Load], so that it can interpret them
according to the conventions of the underlying build system.
See the Example function for typical usage.
