Since tesseract 3.02 it is possible to specify multiple languages for the -l parameter.

-l lang The language to use. If none is specified, English is assumed. Multiple languages may be specified, separated by plus characters. Tesseract uses 3-character ISO 639-2 language codes.

An example:

tesseract myscan.png out -l deu+eng
