Gawk is the GNU Project's implementation of the AWK programming
language.  It conforms to the definition of the language in the POSIX
1003.2 Command Language And Utilities Standard.  This version in turn
is based on the description in "The AWK Programming Language", by Aho,
Kernighan, and Weinberger, with the additional features defined in the
System V Release 4 version of UNIX awk.  Gawk also provides some
GNU-specific extensions.

The command line consists of options to gawk itself, the AWK program
text (if not supplied via the -f or --file options), and values to be
made available in the ARGC and ARGV pre-defined AWK variables.
