@Import pkgtasks-1-1.9 as pkgsrc/pkgtools/pkgtasks.

pkgtasks is a shell script library to ease writing POSIX-compliant
shell scripts to handle common tasks during installation or removal
of a package, e.g.,

  * creating groups and users needed by the package

  * creating and removing directories with special permissions and
    ownership,

  * copying example config files to their final locations during
    package installation, and removing them during package removal
    if they don't differ from the example ones,

  * reminding the user of files that may be customized after
    package installation.

# NAME
#	run_tests -- run all of the test scripts for pkgtasks
#
# SYNOPSIS
#	run_tests [-v] [<script> ...]
#
# DESCRIPTION
#	run_tests runs the test scripts in the ${TASK_TESTS_DIR} directory
#	and reports a summary of the test results.  By default, all of the
#	test scripts are run, but a subset may be selected by passing their
#	names as optional parameters.
#
#	The options are as follows:
#
#	-v	Verbose; run the tests so they produce output to the
#		standard output and error.  By default, the tests are run
#		in quiet mode.
#
#	If this script is run with a basename ending in ".sh", then the
#	tests are assumed to be named also ending in ".sh" and located in
#	the current directory.  This is to allow the tests to be run from
#	their source directory.
#
# EXIT STATUS
#	The script exits with a value of the number of failed tests.
#
