+This directory contains a database for a fake web site.
+Standard web page for the persons listed in db.lua are
+creared automatically from template.html with staff.lua.
+(See http://www.cos.ufrj.br for a real web site was created in this way.)

+To run, type lua db.lua.
+
+This example is meant to show the power of gsub and Lua declarative constructs,
+which have been combined here into a "mail-merge" application.
