The skip keyword tells the program to skip lines at the start of a text
(i.e. not binary) data file. The lines that are skipped do not count toward
the line count used in processing the every keyword. Note that skip N
skips lines only at the start of the file, whereas every ::N skips lines at
the start of every block of data in the file. See also binary skip (p. ) for a
similar option that applies to binary data files.
