[NTG-context] Version Information on each page of text

Hi, I'd like to put the phrase "Version: Fall 2007" on each page of our intermediate algebra textbook. On even-numbered pages, I'd like to put it in the lower left corner of the page, in odd-numbered pages, I'd like it in the lower right corner of the page. I'd like it to be well below the area where footnotes are posted so as not to interfere with foonotes. Any suggestions?
