# Variables (all optional, except GO_PKG) to be set in package
# Makefiles:
#
# GO_PKG (required) - name of Go package
#
# Go name of the package.
#
# e.g. GO_PKG:=golang.org/x/text
#
#
# GO_PKG_INSTALL_EXTRA - list of regular expressions, default empty
#
# Additional files/directories to install. By default, only these
# files are installed:
#
# * Files with one of these extensions:
# .go, .c, .cc, .h, .hh, .proto, .s
#
# * Files in any 'testdata' directory
#
# e.g. GO_PKG_INSTALL_EXTRA:=example.toml marshal_test.toml
#
#
# GO_PKG_INSTALL_ALL - boolean (0 or 1), default false
#
# If true, install all files regardless of extension or directory.
#
# e.g. GO_PKG_INSTALL_ALL:=1
#
#
# GO_PKG_SOURCE_ONLY - boolean (0 or 1), default false
#
# If true, 'go install' will not be called. If the package does not
# (or should not) build any binaries, then specifying this option will
# save build time.
#
# e.g. GO_PKG_SOURCE_ONLY:=1
#
#
# GO_PKG_BUILD_PKG - list of build targets, default GO_PKG/...
#
# Build targets for compiling this Go package, i.e. arguments passed
# to 'go install'
#
# e.g. GO_PKG_BUILD_PKG:=github.com/debian/ratt/cmd/...
#
#
# GO_PKG_EXCLUDES - list of regular expressions, default empty
#
# Patterns to exclude from the build targets expanded from
# GO_PKG_BUILD_PKG.
#
# e.g. GO_PKG_EXCLUDES:=examples/
#
#
# GO_PKG_GO_GENERATE - boolean (0 or 1), default false
#
# If true, 'go generate' will be called on all build targets (as
# determined by GO_PKG_BUILD_PKG and GO_PKG_EXCLUDES). This is usually
# not necessary.
#
# e.g. GO_PKG_GO_GENERATE:=1
# Credit for this package build process (GoPackage/Build/Configure and
# GoPackage/Build/Compile) belong to Debian's dh-golang completely.
# https://anonscm.debian.org/cgit/pkg-go/packages/dh-golang.git
# for building packages, not user code
