The python script that I used was

seperator = ','
for subdir, dirs, files in os.walk(rootdir):
for file in files:
temp = os.path.join(subdir, file)

parts = lines[i].split(seperator)

lines[i] = seperator.join(parts)
print lines[i]

> BTW, why "scheduler"? Could you give a rationale for this name?
I thought as all the system calls are one or the other related to the
scheduler. We can also consider the description "syscalls relate to
scheduling.
