     1  This directory contains some examples/test-cases for different
     2  features of gawk - mostly not present in an old awk.  Some are from
     3  "The GAWK Manual", some are original, and some are mixture of the two.
     4  Read header comments before attempting to use.  Have fun and remember
     5  that program which consists only of BEGIN block does not need an input
     6  file.
