#   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.
