 Advanced Features of `gawk'
 ***************************
 
      Write documentation as if whoever reads it is a violent psychopath
      who knows where you live.

    This major node discusses advanced features in `gawk'.  It's a bit
 of a "grab bag" of items that are otherwise unrelated to each other.
 First, a command-line option allows `gawk' to recognize nondecimal
 numbers in input data, not just in `awk' programs.  Next, two-way I/O,
 discussed briefly in earlier parts of this Info file, is described in
 full detail, along with the basics of TCP/IP networking and BSD portal
 files.  Finally, `gawk' can "profile" an `awk' program, making it
 possible to tune it for performance.
 
     Adding New Built-in Functions to `gawk' Dynamic Extensions,
 discusses the ability to dynamically add new built-in functions to
 `gawk'.  As this feature is still immature and likely to change, its
 description is relegated to an appendix.
