Languages are
imported into the system in language packages. Each language package can
contain one or more transport requests.
To make it easier to organize multiple transport requests for the language
export, they are grouped in a language package. Technically, these language
packages correspond to Support Packages.
This means that a language export also involves the creation of transport
requests and their inclusion in a language package.
You export languages in a user dialog in transaction SMLT_EX.
