#
# This script runs the tests necessary to ensure that a Koha release can be

# be placed in ~/releases or the directory specified by the command-line
# argument.
#
# This script honors the following environment variables:
# SKIP_TESTS: skip the unit test step
# SKIP_DEB: skip all steps related to package building and installation
# SKIP_TGZ: skip all steps related to tarball building and installation
# SKIP_INSTALL: skip testing the package and tarball installation
