How to rtl the the ltr template

hi guys,

i have bought an english template and wana make the my site bilingual.
i have already add the new rtl language but now want to rtl the template too.
actually by pressing the arabic lan it must convert to rtl and by pressing english lan i must convert to ltr.

i would be grateful if some one help me in this case
thanks

I've only ever used english, so am making an educated guess. I'm pretty sure this is controlled in catalog/language/[language]/[language].php, ie. catalog/language/arabic/arabic.php. You should be able to change the direction under Locale settings and change to 'rtl'.
