SFM2Web is a Python3 program that converts materials encoded using SIL's Standard Format Marker format (see a very brief description here) into web pages. The program can convert a lexicon, interlinear texts, Bible books, a multilanguage phrasebook, and language lessons, etc. into xHTML pages with formatting determined by cascading stylesheets (CSS).
These web pages may then be copied to a web server for publication to the Internet or to an intranet. But these aren't the only uses for the web pages. They can also be viewed on a local computer to view and/or check one's own work. Or they can be sent to a dictionary
