# Makefile for the postit Debian package.
#
# Targets:
#   make deb      : build a .deb in the parent directory (or
#                   $POSTIT_OUT_DIR if set). Equivalent to
#                   dpkg-buildpackage -us -uc -b.
#   make test     : run the non-regression tests under tests/.
#                   The fetch test pins the upstream Git mechanics
#                   that previously regressed on tag-vs-branch
#                   handling (1.0.1-rc02). Set SKIP_NETWORK_TESTS=1
#                   to skip the GitHub-egress parts.
#   make clean    : rm -rf build/ and the per-package staging tree
#                   under debian/postit.
#   make source   : fetch the upstream yavsc source tree under
#                   build/yavsc-src (no packaging step). Useful for
#                   debugging the publish step.
#
# Environment overrides (or pass on the make command line):
#   POSTIT_GIT_URL   default: https://github.com/pazof/yavsc.git
#   POSTIT_GIT_TAG   default: 1.0.0
#   POSTIT_RUNTIME   default: linux-x64  (override to linux-arm64 etc.)
#   POSTIT_OUT_DIR   default: $(CURDIR)/..    (artifacts land here)
