+#!/usr/bin/env bats
+#
+# 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##*/}")
