neocomplcache provides keyword completion system by maintaining a cache of keywords in the current buffer. neocomplcache could be customized easily and has a lot more features than the Vim's standard completion feature. Note: neocomplcache may consume more memory than other plugins.
- Extract the file and put files in your Vim directory (usually ~/.vim/ or Program Files/Vim/vimfiles on Windows).
- Execute
|:NeoComplCacheEnable|command orlet g:neocomplcache_enable_at_startup = 1in your.vimrc. Not in.gvimrc(_gvimrc)!
Because all variable names were changed in neocomplcache Ver.5, it is not backwards compatible. If you want to upgrade, you should use the following script from Mr.thinca.
Snippets feature(snippets_complete source) was splitted from Ver.7. If you used it, please install snippets_complete source manually.

Completion with vimshell(http://github.com/Shougo/vimshell).
