# $FreeBSD$
#
# This file contains logic to ease porting of Go binaries using the
# `go` command.
#
# Feature: go
# Usage: USES=go
# Valid ARGS: (none), modules
#
# (none) Setup GOPATH and build in GOPATH mode.
# modules If the upstream uses Go modules, this can be set to build
# in modules-aware mode.
#
# You can set the following variables to control the process.
#
# GO_PKGNAME
# The name of the package. When building in GOPATH mode, this is
# the directory that will be created in GOPATH/src and seen by the
# `go` command. When building in modules-aware mode, no directories
# will be created and GO_PKGNAME value will be only used as a default
# for GO_TARGET. If not set explicitly and GH_SUBDIR is present,
# GO_PKGNAME will be inferred from GH_SUBDIR.
#
# GO_TARGET
# The names of the package(s) to build. If not set explicitly,
# defaults to GO_PKGNAME.
#
# CGO_CFLAGS
# Addional CFLAGS variables to be passed to the C compiler by the `go`
# command
#
# CGO_LDFLAGS
# Addional LDFLAGS variables to be passed to the C compiler by the `go`
# command
#
# GO_BUILDFLAGS
# Additional build arguments to be passed to the `go install` command
