a. read the program from the command line
b. iterate over all the arguments using them as successive
c. automatically split each input line
This makes it easy to write quickie filters.
Perhaps this might be made available for python too? For example,
suppose that -a is autosplit mode and -e reads the python program
from the next argument. Then one might do the following to get
the second field from each line and its square assuming that
Python puts the line into L and then splits it into a list of
python -ae 'print F, F*F'
if you want to read the input from standard input, or
python -ae 'print F, F*F' infile.dat
if you want to name the file explicity.
