Usage

First of all, add require and create new CRYSTALLIX::PAGE:

After that, you can write anything to the page and headers:

page.add "<html><head><title>Crystallix page</title></head>"
page.add "<body>It works with <pre>#{`crystal -v`}!</pre></body></html>"
# code...
page.header("Content-Language", "en")
# any other code...

After you did all your stuff use close to echo contents to STDOUT:

# after all code
page.close

Building

After you did all tests and ready to go, build your executable with

crystal build src/my_page.cr --release --progress -o my_page.crweb

Make sure you got .crweb and use it in Crystallix!
