#
# Available targets
#
# * build -- builds AdGuardHome for the current platform
# * client -- builds client-side code of AdGuard Home
# * client-watch -- builds client-side code of AdGuard Home and watches for changes there
# * docker -- builds a docker image for the current platform
# * clean -- clean everything created by previous builds
# * lint -- run all linters
# * test -- run all unit-tests
# * dependencies -- installs dependencies (go and npm modules)
# * ci -- installs dependencies, runs linters and tests, intended to be used by CI/CD
#
# Building releases:
#
# * release -- builds AdGuard Home distros. CHANNEL must be specified (edge, release or beta).
# * release_and_sign -- builds AdGuard Home distros and signs the binary files.
#   CHANNEL must be specified (edge, release or beta).
# * sign -- Repacks all release archive files and signs the binary files inside them.
#   For signing to work, the public+private key pair for $(GPG_KEY) must be imported:
#     gpg --import public.txt
#     gpg --import private.txt
#   GPG_KEY_PASSPHRASE must contain the GPG key passphrase
# * docker-multi-arch -- builds a multi-arch image. If you want it to be pushed to docker hub,
# 	you must specify:
#     * DOCKER_IMAGE_NAME - adguard/adguard-home
#     * DOCKER_OUTPUT - type=image,name=adguard/adguard-home,push=true
