pashmak has some internal libraries to use. that modules are helpful for you.
you can import modules with import
function.
look at this example:
import '@hash'
import "@module_name"
import "@module1", '@module2'
# also you can import modules without quotes
import @sys
import @hash, @mymodule
# also you can import modules like scripts under the namespaces
namespace Foo
import '@hash'
endns
# ...
you have to give name of module with a @
before that to the include command.
