-// Package gen contains common code for the various code generation tools in the
-// text repository. Its usage ensures consistency between tools.
-//
-// This package defines command line flags that are common to most generation
-// tools. The flags allow for specifying specific Unicode and CLDR versions
-// in the public Unicode data repository (http://www.unicode.org/Public).
-//
-// A local Unicode data mirror can be set through the flag -local or the
-// environment variable UNICODE_DIR. The former takes precedence. The local
-// directory should follow the same structure as the public repository.
-//
-// IANA data can also optionally be mirrored by putting it in the iana directory
-// rooted at the top of the local mirror. Beware, though, that IANA data is not
-// versioned. So it is up to the developer to use the right version.
