# Script to initialize a taler-exchange database.
# To use as an alternative to the taler-exchange-dbinit tool.
#
# This script aggregate GNU Taler exchange's SQL files together,
# and send commands to PostgreSQL server with `psql`.
# Usage:
# `fetch`
# fetch all *.sql and *.sql.in files from GNU Taler exchange repository
# `build`
# merge *.sql and *.sql.in files to produce `init.sql` and `drop.sql`
# `database_init`
# create a `taler-exchange` database
# `database_drop`
# drop `taler-exchange` database
# `init`
# apply `init.sql`
# (database must already be created)
# `drop`
# apply `drop.sql`
