...If you enter '.textile' file name in the minibuffer, textile file is automatically generated and you can write a blog with textiles. The browser opens automatically and you can preview the blog on your laptop or desktop. Even if you run the easy-Jekyll-preview command many times, only one Jekyll process will run so do not mind it. Since the process of Jekyll running on the laptop or desktop disappears in 300 seconds, you do not have to worry about killing the Jekyll process.
