sub Help {
    print <<EOF;

A program to help generate bug reports about perl5, and mail them.
It is designed to be used interactively. Normally no arguments will
be needed.

Usage:
$0  [-v] [-a address] [-s subject] [-b body | -f file ]
    [-r returnaddress] [-e editor] [-c adminaddress | -C] [-S] [-t]

Simplest usage:  run "$0", and follow the prompts.

Options:

  -v    Include Verbose configuration data in the report
  -f    File containing the body of the report. Use this to
        quickly send a prepared message.
  -S    Send without asking for confirmation.
  -a    Address to send the report to. Defaults to `$address'.
  -c    Address to send copy of report to. Defaults to `$cc'.
  -C    Don't send copy to administrator.
  -s    Subject to include with the message. You will be prompted
        if you don't supply one on the command line.
  -b    Body of the report. If not included on the command line, or
        in a file with -f, you will get a chance to edit the message.
  -r    Your return address. The program will ask you to confirm
        this if you don't give it here.
  -e    Editor to use.
  -t    Test mode. The target address defaults to `$testaddress'.
  -d    Data mode (the default if you redirect or pipe output.)
        This prints out your configuration data, without mailing
        anything. You can use this with -v to get more complete data.
