# Makefile for building the test database

#

# Makefile targets:

#

# all           build and install the database

# clean         clean build products and intermediates

#

# Variables to override:

#

# MIX_APP_PATH  path to the build directory

# CC_FOR_BUILD  C compiler



# Since this is for test purposes, be sure this matches what the tz (or tzdata)

# libraries use or you'll get discrepancies that are ok.
