# Or: gtk3-nocsd evince
#
# Create a symlink to this wrapper script with the name of the program
# you want run without client-side decorations. This wrapper script
# will run the first matching executable in the PATH that is *not* a
# symlink to gtk3-nocsd. This wrapper script is useful if you don't
# want to add gtk3-nocsd to your system-wide LD_PRELOAD or if you only
# want it applied to certain applications.
#
# Alternative mode of operation: call this wrapper directly with the
# program to call as its arguments.
