How can i write a specific page for a module? For example, imagine
that i have a module called monedas and i need be able to access to a
url like:
http://localhost/monedas
exactly like, for example, the postcard module. It has a function
named postcard_page, but i havenīt find any documentation about this
hook.
thanks a lot in advance
