 #
 # Purpose
 #
-# Show symbols in the X.509 and TLS libraries that are defined in another
-# libmbedtlsXXX.a library. This is usually done to list Crypto dependencies.
+# Show external links in built libraries (X509 or TLS) or modules. This is
+# usually done to list Crypto dependencies or to check modules'
+# interdependencies.
 #
 # Usage:
 # - build the library with debug symbols and the config you're interested in
 #   (default, full minus MBEDTLS_USE_PSA_CRYPTO, full, etc.)
-# - run this script with the name of your config as the only argument
+# - launch this script with 1 or more arguments depending on the analysis' goal:
+#     - if only 1 argument is used (which is the name of the used config,
+#       ex: full), then the analysis is done on libmbedx509 and libmbedtls
+#       libraries by default
+#     - if multiple arguments are provided, then modules' names (ex: pk,
+#       pkparse, pkwrite, etc) are expected after the 1st one and the analysis
+#       will be done on those modules instead of the libraries.
