# Makefile for the XML Query extension (XQuery/XPath embedded in SQL)
#
# Targets:
#   all      - Build the demo and compile grammars
#   grammars - Generate parsers from .lime grammar files
#   demo     - Build the standalone demo program
#   test     - Run the demo (basic smoke test)
#   clean    - Remove generated files
#
# Prerequisites:
#   - lime binary built at ../../lime
#   - gcc or compatible C compiler
