 Invoking `awk'
 ==============
 
    There are two ways to run `awk'--with an explicit program or with
 one or more program files.  Here are templates for both of them; items
 enclosed in [...] in these templates are optional:
 
      awk [OPTIONS] -f progfile [`--'] FILE ...
      awk [OPTIONS] [`--'] 'PROGRAM' FILE ...
 
    Besides traditional one-letter POSIX-style options, `gawk' also
 supports GNU long options.
 
    It is possible to invoke `awk' with an empty program:
 
      awk '' datafile1 datafile2
 
 Doing so makes little sense, though; `awk' exits silently when given an
 empty program.  (d.c.)  If `--lint' has been specified on the command
 line, `gawk' issues a warning that the program is empty.
