To submit your program source files, use the command:
% submit_cps214 assign_num [file1 file2 ...]
For the first xkernel assignment, assign_num is p1. Thus, you would submit your programs via something like:
% submit_cps214 p1 graph.comp intro_tcp.c intro_udp.c ...
Note: You can only submit files in the current directory (i.e., no files in subdirectories).
To see what files have actually been sumbitted, run the command without listing any files (but do list the assignment number). For example:
% submit_cps214 p1
