# Build and upload custom packages to the f3s package repository.
#
# Usage:
#   make pkg NAME=gogios SRC=~/git/gogios          # both FreeBSD + OpenBSD
#   make pkg-freebsd NAME=gogios SRC=~/git/gogios   # FreeBSD only
#   make pkg-openbsd NAME=gogios SRC=~/git/gogios   # OpenBSD only
#
# Required variables:
#   NAME  — package name (e.g. gogios)
#   SRC   — path to the Go project root (must have cmd/$(NAME)/main.go
#           and internal/version.go with a Version constant)
#
# Optional variables:
#   COMMENT     — one-line package description
#   DESC        — longer description (for OpenBSD desc file)
#   MAINTAINER  — maintainer email
#   WWW         — project URL
#   ENTRY       — Go main package path relative to SRC (default: cmd/$(NAME)/main.go)
