Greek in LaTeX

It was obvious tha sooner or later I would be in need to use greek in my LaTeX texts. To use them the Babel package is needed so (here in use with English):

`\usepackage[english,greek]{babel}`

then by choosing `\foreignlanguage{greek}` or `\selectlanguage{english}` you switch between languages. However you cannot use greek letters but latin ones to write in Greeks. so writing: `Kalhm’era ` would yield: `Καλημέρα.`

If you need to use the Greek characters then the:

`\usepackage[iso-8859-7]{inputenc}`

is necessary. While using that you can switch between the encodings (latin and greek) using `\latintext` and `\greektext`.
