10 # Warnings:
11 # - parser it's pretty stiff about multi-line www-sql tabs. Only allowed
12 # multiline tags are: print_rows, query
13 # - like operators in PostgreSQL ARE case sensitive -- your appl. may not
14 # work because of that!
15 # - you WILL NEED TO CHANGE links and/or missed form actions by hand!
16 # - www-sql permits variables with slash (-) in name, php doesn't!
