[aur-general] install instead of mkdir and cp, was: Re: TU application

Out of curiosity:

* Use install(1) instead of mkdir(1) and cp(1).

Why? I find the install command sometimes a bit uncomfortable, especially if you have to copy a hierarchy of directories (and their content). What is the advantage of install over mkdir and cp? Is there a solution for reversively copying directories using install? Cheers, Christoph
