# flake.nix - LARQL Nix packaging
#
# Quick Start:
#   nix build                         # Build larql-cli binary
#   nix develop                       # Development shell
#   nix flake show                    # List all outputs
#
# Demo (models fetched via git-lfs, vindexes built at nix-build time):
#   nix run .#demo-list               # List available models
#   nix run .#demo                    # Walk default model (gemma4-4b)
#   nix run .#demo-<key>              # Walk a specific model
#   nix run .#demo-info               # Show GGUF metadata for local models
#   nix build .#vindex-<key>          # Build a vindex from a model
#
# OCI Containers (Linux only):
#   nix build .#container             # larql-server image
#   nix build .#container-cli         # larql CLI image
#   docker load < result
#
# See also: ./nix/README.md
