nimWebTemplates is ABADONNED and DEPRECATED
for a better template engine use: enthus1ast/nimja
readme
nwt is a little template engine inspired by jinja2.
(warning: it lacks control statements like if while etc..)
it do not enforce any web framework so use whatever you like!
rudimentary freeze support with freeze()
have a look at the other demos!
if you feeling fancy today have a special look at the dbdriven database example and
my little flatfile database flatdb for nim-lang
usage
