# -------------------------------------------------------------
# This makefile defines the following targets
#
#   - all (default) - builds all targets and runs all tests/checks
#   - checks - runs all tests/checks
#   - peer - builds the fabric peer binary
#   - membersrvc - builds the membersrvc binary
#   - unit-test - runs the go-test based unit tests
#   - behave - runs the behave test
#   - behave-deps - ensures pre-requisites are availble for running behave manually
#   - gotools - installs go tools like golint
#   - linter - runs all code checks
#   - images[-clean] - ensures all docker images are available[/cleaned]
#   - peer-image[-clean] - ensures the peer-image is available[/cleaned] (for behave, etc)
#   - membersrvc-image[-clean] - ensures the membersrvc-image is available[/cleaned] (for behave, etc)
#   - protos - generate all protobuf artifacts based on .proto files
#   - node-sdk - builds the node.js client sdk
#   - node-sdk-unit-tests - runs the node.js client sdk unit tests
#   - clean - cleans the build area
#   - dist-clean - superset of 'clean' that also removes persistent state
