+# This script scans Xcode directores for unknown frameworks
+# and tries to add them as Kotlin/Native def files.
+#
+# Note that some frameworks are unsupported (e.g. swift-only) and marked as .disabled.
+# Others may be supported and manual adjustment required (.attention_required).
+# Don't consider this script as a fully automatic solution. It tries its best
+# to identify unsupported frameworks correctly, but the result still should be validated.
+#
+# jq is required to run the script. It can be installed via `brew install jq`.
+#
+# Args:
+# 1. Platform name: ios, tvos, osx or watchos
+# 2. Path to Kotlin/Native sources.
