+# include-what-you-use mapping file for CLI11.
+#
+# Both standard libraries make IWYU ask for a header that CLI11 must not
+# include: libc++ (macOS) exposes private detail headers, libstdc++ (Linux)
+# exposes the C headers behind <cXXX>. Name the C++ header instead.
+#
+# Prefer a symbol entry. An include entry only takes effect when the left side
+# is private, and declaring a real C header private makes IWYU abort with a
+# "same file seen with two different visibilities" assertion.
