, or SOuRce Data pushes are periodic distributions of new member-developed content
to the servers, to be subsequently downloaded on demand by members' client machines. This content consists of model (*.model) files, texture (*.dds and *.ave) files, and in the case of vehicles, configuration (*.aconf) files. The configuration files are written in Lua 
code, but a push is considered source data to distinguish it from executable machine code which is downloaded (pulled) from a server to a member's client machine during an upgrade procedure.
