homeassistant: Add 0.0

This is a package that, for the moment, does nothing, but depends on
packages required when installing Home Assistant in a virtual
environment.  Eventually, it will contain scripts to manage building
and using Home Assistant in that environment

(This package exists because it is too hard to package Home Assistant,
because almost all dependencies are exact.)

+HOMEPAGE=	https://www.home-assistant.io/
+COMMENT=	Meta-package for prereqs for Home Assistant
+
+# Revisit when it becomes nontrivial.
+LICENSE=	modified-bsd
+
+META_PACKAGE=	yes
+
+# This package intends to set up for the union of reasonable Home
+# Assistant (HA) installations within a venv, erring on the side of
+# depending on more rather than less.  The vast majority of HA
+# components (integrations, or the core) are just python, often
+# depending on another python module.  These build straightforwardly
+# with "bin/pip install".  However, some modules depend on C
+# libraries, some depend on Fortran, and some use rust to build.  This
+# package is primarily intended to ease those issues.
+
+# This package is currently tuned for NetBSD 9.
+
+# The set of packages wrapping libraries is currently:
+#   - cryptography (http for SSL)
+#   - postgresql (standard approach for database)
+#   - sqlite3 (testing approach for database)
+#   - av and numpy (stream component, which is part of default config)
+#   - PIL (needed by 8 components)
+# and build tools
+#   - pkg-config
+#   - rust (for cryptography in the venv)
+#   - gfortran (for numpy in the venv)

+### NEEDED WORKAROUNDS
+# \todo Hoist these somehow to a script or fix upstream.
+# This section describes workarounds to enable the venv to build.
+
+## ha-av
+#
+# ffmpeg4 installs to /usr/pkg/lib/ffmpeg4, but pkg_alternatives does
+# not provide library links.  A strategy that works is to symlink from
+# /usr/pkg/lib, and a strategy that might work is to PKG_CONFIG_PATH.
+#
+# ffmpeg's pkgconfig files have "-Wl,-rpath,/usr/pkg/lib/ffmpeg4/lib",
+# but PyAV's setup.py is buggy and looks at flags to see if they are
+# known and doesn't support -Wl,-rpath.  Changing to -R makes it work.
+# This is a bug in PyAV.  \todo File a fix.
+
+## cryptography
+# As of 40, the build fails to find openssl on NetBSD 9, likely a bug.
+# https://docs.rs/openssl/latest/openssl/#automatic advises
+#   export OPENSSL_DIR=/usr
