# @ECLASS-VARIABLE: EGO_BUILD_FLAGS
# @DEFAULT_UNSET
# @DESCRIPTION:
# This allows you to pass build flags to the Go compiler. These flags
# are common to the "go build" and "go install" commands used below.
# Please emerge dev-lang/go and run "go help build" for the
# documentation for these flags.
#
# Example:
# @CODE
# EGO_BUILD_FLAGS="-ldflags \"-X main.version ${PV}\""
# @CODE

# @ECLASS-VARIABLE: EGO_PN
# @REQUIRED
# @DESCRIPTION:
# This is the import path for the go package(s) to build. Please emerge
# dev-lang/go and read "go help importpath" for syntax.
#
# Example:
# @CODE
# EGO_PN=github.com/user/package
# @CODE
