I am using `.po` and `.mo` files for translating my website.
My question is, is it possible to pass parameters into a translated sentence in a [.po translation file](http://www.gnu.org/software/hello/manual/gettext/PO-Files.html)?

For example:
en -> Hi, my name is Sarah, and I am an alcoholic
I want to translate that sentence using two params, name (Sarah) and profession (an alcoholic).

Thank you in advance.
