Do not edit this generated file which gives the stdout results of
pltcl running the command "source bindings/tcl/test_tclmatrix.tcl"
to test the matrix capabilities of libtclmatrix.  Instead, check its
consistency with the latest pltcl, libtclmatrix, and
bindings/tcl/test_tclmatrix.tcl by building the (Unix) target
"check_libtclmatrix_capabilities" which creates the latest version
of this file in bindings/tcl/test_tclmatrix.out_compare in the build
tree and compares that version with bindings/tcl/test_tclmatrix.out
in the source tree.  If that target fails because the two versions
of that file are different, diff the build-tree version with the
source tree version to help evaluate the differences, and if those
differences seem reasonable (say due to a known change in
bindings/tcl/test_tclmatrix.tcl in the source tree), then copy the
build-tree version of this file back to the source tree, verify the
result by running the "check_libtclmatrix_capabilities" target,
and then commit the new version of the source-tree version.
