You can either use file:read_file() and binary_to_list(), followed by
string:tokens(List, "\n") -- which will give you a list of strings, one for
each
line of text in the file -- or use io:get_line(FileDescr,'') to read one
line
at a time from the file.

(regexp:split() will also work, but in this case, I think string:tokens/2 is
better.)

Note that reading one line at a time from the file will give better
memory characteristics.
