  15         There are two ways for you to make a bug report. One uses a
  16         simple perl script, and is recommended if you don't want to
  17         spend a lot of time producing the report. It is designed for
  18         use by just about anyone, from the newest of newbies to
  19         advanced developers. You can also make a bug report the hard
  20         way -- advanced developers will probably prefer this.

  28               Your computer *must* have perl on it for this method to
  29               work. To find out if you have perl, run <command>which
  30                 perl</command>. If it returns something like
  31               <filename>/usr/bin/perl</filename>, you're in business.
  32               Otherwise, skip on down to "The Hard Way". If you aren't
  33               sure, just keep on going. When you try to run the
  34               script, it will become *very* apparent if you don't have
  35               perl.

  65           Some simple advice on making your bug report more useful

  72               This means we need more information than a simple "MS

 119               If Wine crashes while running your program, it is
 120               important that we have this information to have a chance
 121               at figuring out what is causing the crash.  This can put
 122               out quite a lot (several MB) of information, though, so
 123               it's best to output it to a file.  When the <prompt>Wine-dbg></prompt>
 124               prompt appears, type <userinput>quit</userinput>.

 130               <parameter>+snoop</parameter> is pretty unstable and
 131               often will crash earlier than a simple
 132               <parameter>+relay</parameter>! If this is the case, then
 133               please use *only* <parameter>+relay</parameter>!! A bug
 134               report with a crash in <parameter>+snoop</parameter>
 135               code is useless in most cases!

 151                     auto-quit. It's probably a good idea to use this command, since wine
 152                     prints out so many debug msgs that they flood the terminal, eating CPU.)
