[pahaz]

Sory, but it`s not work for me.

> bem create block itest

WARNING!
Command "bem create block" is deprecated!
It will be removed in bem-tools@1.0.0, please use `bem create -b ...` command instead.


WARNING!
Tech module "app" at ...\DJANGO_BEM_TEST\bem-django\.bem\techs\app.js is using API V1.
Tech modules API V1 is not recommended to use, because it is slow.
Please use tech modules API V2, it makes your build process faster!
