cdocs - urfave/cli/v2 docs extension

This is an enhanced version of the ToMarkdown and ToMan methods for https://github.com/urfave/cli/v2.

cdocs also provides a helper command InstallManpageCommand that will generate a CLI command to install a man page to the system for the CLI tool.

Key differences are:

• Addition of a Table of Contents with working markdown links.
• UsageText included in generated doc files.
• InstallManpageCommand helper command.

Examples:

• gwsm
• gwvault
• gw-aws-audit

)

func main() {
	im, err := cdocs.InstallManpageCommand(&cdocs.InstallManpageCommandInput{

	if err != nil {
