# Makefile for the SQLite Compatibility Grammar Extension
#
# Builds:
#   - sqlite_compat.so   : Shared library for dynamic loading
#   - test_sqlite_compat : Test runner for the extension
#
# Usage:
#   make                 - Build shared library
#   make test            - Build and run tests (semantic tests only)
#   make clean           - Remove build artifacts
#
# Prerequisites:
#   - Lime parser generator built in ../../
#   - Extension system headers in ../../include and ../../src
