"-- FUNCTION: \n"
"-- Define the tables needed to initialize a new GnuCash database \n"
"-- \n"
"-- These tables roughly mirror the c structs in  \n"
"-- TransactionP.h,  AccountP.h, gnc-commodity.c \n"
"-- Please refer to the C files to get the right level of documentation. \n"
"-- \n"
"-- If these tables are changed or added to, a correspionding \n"
"-- audit-trail table (in table-audit.sql) must be updated as well. \n"
"-- \n"
"-- These tables are specifically designed for the  \n"
"-- postgres database server, but are hopefull relatively portable. \n"
"-- \n"
"-- These tables are hand-built, but maybe they should be  \n"
"-- auto-built with the m4 macros ... \n"
