# 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.

# It is not needed when building in modules-aware mode.

# GO_TARGET
# The names of the package(s) to build. If not set explicitly,
# defaults to GO_PKGNAME.
# The packages to build. If not set explicitly, defaults to
# GO_PKGNAME. GO_TARGET can also be a tuple in the form
# package:path where path can be either a simple filename or a
# full path starting with ${PREFIX}. Specifying a full path
# like ${PREFIX}/sbin/binary will install the resulting binary
# as ${PREFIX}/sbin/binary. Using just simple filename is a
# shortcut to installing it as ${PREFIX}/bin/filename.
