# With this script you can run all the virt tools without needing to
# install them first. You just have to do for example:
#
# ./run ./inspector/virt-inspector [args ...]
#
# This works for any C program, virt tools, and most non-C bindings
# and programs in the libguestfs distribution. Also you can make a
# symbolic [not hard] link to this 'run' script from anywhere
# (eg. $HOME/bin/run) if you wish.
#
# The script can also be used to make the output of tests shorter:
# TESTS_ENVIRONMENT = ... $(top_builddir)/run --test [$(VG)]
# (Use the optional $(VG) when the tests must also be run under
# valgrind).
