+#!/bin/sh
+#
+#  This testing wrapper was written by James Le Cuirot.
+#
+#  It runs all the programs in AUTO_REG_PROGS in Makefile.am
+#  when the command 'make check' is invoked.  This same set can
+#  be run by doing:
+#      alltests_reg generate
+#      alltests_reg compare
+#
+#  Some of the tests require gnuplot.  These tests, listed below,
+#  are skipped if gnuplot is not available.  You can determine if a
+#  test requires gnuplot, if any of these situations is true:
+#   * a function starting with "gplot" is called
+#   * a function starting with "boxaPlot" is called
+#   * a function starting with "pixCompare" is called
+#   * the function pixItalicWords() is called
+#   * the function pixWordMaskByDilation() is called
+#
+#  The wrapper receives several parameters in this form:
+#      path/to/source/config/test-driver <TEST DRIVER ARGS> -- ./foo_reg
+#
+#  Shell trickery is used to strip off the final parameter and
+#  transform the invocation into this.
+#      path/to/source/config/test-driver <TEST DRIVER ARGS>
+#      -- /bin/sh -c "cd \"path/to/source/prog\" &&
+#      \"path/to/build/prog/\"./foo_reg generate &&
+#      \"path/to/build/prog/\"./foo_reg compare"
+#
+#  This also allows testing when you build in a different directory
+#  from the install directory, and the logs still get written to
+#  the build directory.
