Simple config file reader for Golang applications

Users often forget quotes, separators, braces and don't want to learn syntax of json, xml, yaml, toml, whateverML to create or edit config files.

Installation:

go get github.com/is73/cfg

Test:

go test github.com/is73/cfg

Features:

• First word on line is a key name, can't contain white space
• Sections can be emulated using key prefix
• Key duplicity is not allowed
• Any white space after first word, space or tab (even multiple), is a key value separator
• Anything after separator except new line character is the value of the key
• Values may contain white space characters
• Lines without value are ignored
• Empty lines are ignored
