Vimana supports for Makefile and Rakefile now. most vim script projects on github have its own rakefile or makefile, so that if a archive file (tar, tar.gz, zip) contains a makefile, rakefile or vim meta file. Vimana would use makefile/rakefile or meta file as its installer strategy.
and I tried to reduce some dependencies, so that installation won't be such pain.
I also added script inspecting feature, which inspects the script code to decide where to installer. colorscheme, compiler ,indent types are supported.
current tested cases:
$ vimana install the-nerd-tree
$ vimana install autocomplpop
$ vimaan install gsession.vim
$ vimana install snipmate
$ vimana i svg.vim
$ vimana i railscasts-theme
$ vimana i dark-ruby
$ vimana i bufexplorer.zip
$ vimana i xml.vim
well, i still need more test cases. ;-)
