#!/bin/sh

# Run the go-x11proto XTS (wire-protocol round-trip) tests against a freshly
# built Xvfb.  These are Go tests in the go-x11proto xts/ package that start
# their own server via -displayfd, so they never touch the host display.
#
# The test is skipped (exit 77) when GOXPROTO_DIR is unset or Go isn't found,
# so it's harmless on systems without the go-x11proto tree.
#
# Required environment:
#   GOXPROTO_DIR      root of the go-x11proto repository
#   XSERVER_BUILDDIR  build directory root
#
# Optional environment:
#   GO                go binary (default: go)
#   XTS_XSERVER       server binary (default: $XSERVER_BUILDDIR/hw/vfb/Xvfb)
#   XTS_XSERVER_ARGS  server arguments (see below for default)
