#   Winelauncher
#       This shell script attempts to intelligently manage the process
#   of launching a program with Wine.  It adds some level of
#   visual feedback to an end user.
#  
#   Usage:
#       winelauncher [options]  "<windows program> [program arguments]"
#
#       This script is meant to be installed to /usr/bin/wine, and
#   to be used to invoke a Windows executable.
#       The options are passed through directly to Wine, and are
#   documented in the Wine man page.

        You have started Wine without specifying any arguments.

        Wine requires a least one argument - the name of the Windows
        application you would like to run.

        If you have launched this through the KDE menu system,
        you can use the KDE file browser to select a Windows
        exectuable and then click on it to launch Wine with
        that application.

        You can similarly use the GNOME file manager to
        select a Windows executable and double click on it.

        If you would like to see the command line arguments
        for Wine, select the second option, below.

effect Wine's behaviour is to change whether or not
Wine uses a true Windows partition, mounted under Linux,

The Wine Configuration program can assist you in making
