##Changelog:
##August 29, 1999 - Work around for debugger exit (or lack thereof)
##                - Should now put debugging output in correct place
##April 19, 1999 - Much nicer way to select Wine's location
##               - Option to disable creation of a debugging output
##               - Now places debugging output where it was started
##April 4, 1999 - Sanity check for file locations/wine strippedness
##              - Various code cleanups/fixes
##March 21, 1999 - Bash 2.0 STDERR workaround (Thanks Ryan Cumming!)
##March 1, 1999 - Check for stripped build
##February 3, 1999 - Fix to chdir to the program's directory
##February 1, 1999 - Cleaned up code
##January 26, 1999 - Fixed various bugs...
##                 - Made newbie mode easier
##January 25, 1999 - Initial Release

        What is your level of Wine expertise? 1-newbie 2-intermediate 3-advanced

        1 - Makes a debug report as defined in the Wine documentation. Best
            for new Wine users. If you're not sure what WINEDEBUG is, then
            use this mode.
        2 - Makes a debug report that is more customizable (Example: you can
            choose what WINEDEBUG to use). You are asked more questions in
            this mode. May intimidate newbies.
        3 - Just like 2, but not corner cutting. Assumes you know what you're
            doing so it leaves out the long descriptions.

        This program will make a debug report for Wine developers. It generates
        two files. The first one has everything asked for by the bugreports guide;
        the second has *all* of the debug output, which can go to thousands of
        lines.
        To (hopefully) get the bug fixed, report it to the project
        bug tracking system at http://bugs.winehq.org.
        Attach the first file to the bug description.
        Also include detailed description of the problem. The developers
        might ask you for "the last X lines from the report". If so, just
        provide the output of the following command:
            gzip -d (output file) | tail -n (X) > outfile

Great! We're finished making the debug report. Please go to http://bugs.winehq.org
and enter it as a new bug. Check that nobody has already reported the same bug!

The filename for the formatted report is:

Note that it is $dbgoutfile.gz, since I compressed it with gzip for you.
