flagconfig example

This example shows how you can use flagconfig to easily parse options off either the command line or a configuration file. If you call go run main.go (assuming flagconfig is installed on your command-line) then you will see the default values for three parameters, --foo and --bar and --baz. You can use -h to see all options.

--example

flagconfig can read the configuration from a configuration file. These files have a very simple syntax that you'll be able to easily pick up at a glance. You can use the --example flag to dump your application's example configuration to stdout (which can then be piped to a file).

--config

You can specify a configuration file for flagconfig to read in and attempt to populate the defined paramters with. If a parameter is defined on the command-line AND in a configuration file then the command-line value takes precedence. If it's not defined in either then the default value specified is used.
