Have each group member fill in the copy whatever functions that they were assignedfrom Fardad's iof.c to our iof.c. (I will fill in the unassigned ones, as well). They should do this in their own branches of trunk. Branches can be made in xcode using the copy command in the Repositories window- other platforms may be similar. The project file, when opened, will automatically know that it's a branch and will commit to the correct branch directory. Once you've filled in the functions and your code is compiling, then commit whatever you've done to the branch.
