## Installation
To use a tagged revision:
go get gopkg.in/ini.v1
To use with latest changes:
go get github.com/go-ini/ini
### Testing
If you want to test on your machine, please apply `-t` flag:
go get -t gopkg.in/ini.v1

If you do not want any auto-transformation (such as recursive read) for the values, you can get raw value directly (this way you get much better performance):

To get value with types:
