flags sub package moved

The flags sub package has been moved to gitHub.com/pborman/flags.

Make the flags sub package more generic

v1.4.1

Make it possible to use other flag packages.

Add support for the standard flag package

This release includes the flags subpackage which is similar to the options package but works with the standard flag package.

The flags subpackage is subject to change at this point.

Minor fix to test code

It appears options_test.go was corrupted causing the build to fail.

Minor usability improvemnts

Make the options package more standalone by adding wrappers for

getopt.PrintUsage
getopt.Usage
getopt.SetParameters
getopt.SetProgram
getopt.SetUsage

And enable setting of getopt global variables with:

SetDisplayWidth
SetHelpColumn

Add SubRegisterAndParse

SubRegisterAndParse is similar to RegisterAndParse but the caller provides the arguments and it returns an error rather than exiting the program on error. This is useful when parsing sub commands.

Documentation Update

This is a minor update improving documentation and adding an additional test on using custom types that implment getopt.Value.

Easy Go Option Parsing

This release adds a new type, options.Help to support displaying help. Normal usage is:

var opts = struct {
	Help    options.Help  `getopt:"--help  display help"`
	...
}

With this, if --help is provided on the command line the command's usage information will be display on standard output and the command will exit with a status of 0.

Initial release of the options package

This is the initial release of the options package. Future changes should be backwards compatible.
