#
# This suite is dedicated to calculating BATS_ROOT when going through various
# permutations of symlinks. It was inspired by the report in issue #113 that the
# calculation was broken on CentOS, where /bin is symlinked to /usr/bin.
#
# The basic test environment is (all paths relative to BATS_TEST_TMPDIR):
#
# - /bin is a relative symlink to /usr/bin, exercising the symlink resolution of
# the `bats` parent directory (i.e. "${0%/*}")
# - /usr/bin/bats is an absolute symlink to /opt/bats-core/bin/bats, exercising
# the symlink resolution of the `bats` executable itself (i.e. "${0##*/}")
