-# cfg
-
-[![GoDoc](https://godoc.org/github.com/wiggin77/cfg?status.svg)](https://godoc.org/github.com/wiggin77/cfg)
-[![Build Status](https://travis-ci.org/wiggin77/cfg.svg?branch=master)](https://travis-ci.org/wiggin77/cfg)
-
-Go package for app configuration. Supports chained configuration sources for multiple levels of defaults.
-Includes APIs for loading Linux style configuration files (name/value pairs) or INI files, map based properties,
-or easily create new configuration sources (e.g. load from database).
-
-Supports monitoring configuration sources for changes, hot loading properties, and notifying listeners of changes.
-
-## Usage
-
-```Go
-config := &cfg.Config{}
-defer config.Shutdown() // stops monitoring
-
-// load file via filespec string, os.File
-src, err := Config.NewSrcFileFromFilespec("./myfile.conf")
-if err != nil {
-    return err
-}
-// add src to top of chain, meaning first searched
-cfg.PrependSource(src)
-
-// fetch prop 'retries', default to 3 if not found
-val := config.Int("retries", 3)
-```
-
-See [example](./example_test.go) for more complete example, including listening for configuration changes.
-
-Config API parses the following data types:
-
-| type    | method | example property values |
-| ------- | ------ | -------- |
-| string  | Config.String  | test, "" |
-| int     | Config.Int     | -1, 77, 0  |
-| int64   | Config.Int64   | -9223372036854775, 372036854775808 |
-| float64 | Config.Float64 | -77.3456, 95642331.1 |
-| bool    | Config.Bool    | T,t,true,True,1,0,False,false,f,F |
-| time.Duration | Config.Duration | "10ms", "2 hours", "5 min" * |
-
-\* Units of measure supported: ms, sec, min, hour, day, week, year.
