Map language names used in the cPanel Legacy Language system to the new locale codes used in the Cpanel::Locale system.

Options:
  --help Show this help screen
  --man  Show the help screen and additional information

Multiple legacy language names can be specified as input.

Example:

    $0 French
    $0 fr French italiano spanish-utf8
    $0 fr French スペイン語 italiano spanish-utf8 中文 DANISH.lng Swedish.special "Heart cPanel"
END_HELP

}

sub show_man {

    show_help();

    print <<"END_MAN";

The cPanel legacy language system used arbitrary language names for identification.
The current Cpanel::Locale uses standard ISO language (and territory) codes to identify locales.
The Cpanel::Locale codes are also based on CLDR (http://cldr.unicode.org) which have locale data
defined accordingly. This utility is used for looking up the corresponding Cpanel::Locale code.

Any specified language/locale names that cannot be mapped are turned in to “i_” tag codes.
An “i_” tag is a standard way to create, identify, and work with a non-standard locale
by prefixing the code with the letter “i” followed by an underscore.
(e.g. i_abcdef, i_qa)
