# Usage: and targets:
#   [LAVA_BUILD_OPTIONS=...] [ENV...] make [TARGET...]
#
# Binaries:
#   lavad               - binary to run for nodes and validators
#   lavap               - binary to run for providers
#
# Targets:
#   (the output of builds goes to $(BUILD_DIR), by default: build/*)
#
#   build-[BIN]         - local build of select binary; [BIN] is one of "Binaries" (or "all")
#   build               - equivalent to build-$(LAVA_BINARY) if set (if not set: error)
#
#   install-[BIN]       - local install of select binary; [BIN] is one of "Binaries" (or "all")
#   install             - equivalent to install-$(LAVA_BINARY) if set (if not set: error)
#
#   docker-build-[BIN]  - docker build of select binary; [BIN] is one of "Binaries" (or "all")
#   docker-build        - equivalent to docket-build-$(LAVA_BINARY) if set (if not set: error)
#
#   build-images        - build both amd64,arm64 lavad(s) and docker image(s)
#   build-image-amd64   - docker build (output: `$(BUILD_DIR)/*-linux-amd64`) with docker image
#   build-image-arm64   - docker build (output: `$(BUILD_DIR)/*-linux-arm64`) with docker image
#
#   proto-gen           - (re)generate protobuf file
#   test                - run unit-tests
#   lint                - run the linter
#
# Options:
#   (comma separated list of options to turn on specific features)
#
#   static	            - build static binary
#   release	            - generate release build
#   nostrip	            - do not strip binary from paths
#
#   debug_mutex         - (debug) enable debug mutex
#   mask_consumer_logs  - (debug) enable debug mutex
#
#   cleveldb, rocksdb   - (not to be used)
# 
#   production-log-level - logs for errros related to bad usage (rather than bugs) set as warnings
#
# Environment
#   LAVA_VERSION=...    - select lava version (for 'release')
#   LAVA_BINARY=...     - select binary to build: "lavad", "lavap", or "all"
#   BUILDDIR=...        - select local directory for build output
#   LEDGER_ENABLED      - (not to be used)
#
# Examples:
#
#   Build locally and run unit tests
#     make test build
#
#   Build locally static binaries (runs on any distributions and in containers)
