What's the difference?

[zhaocai]

Stumbled upon this plugin... Seems like a combination of a few of my favorite plugins.

Could you describe in a few sentence about what the difference is? What are the objectives of this plugin?

Thanks.

activefix main objectives is syntax checking automatically and asynchronously.

syntastic cannot syntax check asynchronously.
There are pull requests that makes syntastic async, such as vim-syntastic/syntastic#146, but there are not accepted.

quickrun can run syntax checkers asynchronously, but needed to add some plugins for displaying syntax errors like syntastic, such as output for location list, highlight error location and display error to command window.

I want to a plugin that do not depend on other plugins but it is necessary to depend only vimproc.
So I'm creating this plugin.
