     .. [1] C++20 modules are *not* supported.
-    .. [2] Objective-C, Objective-C++, C++/CLI, and C++/CX are not supported.
-    .. [3] Support for the clang-cl compiler is preliminary.
-    .. [4] Support for the Arm Compiler (armcc) is preliminary.
-    .. [5] Builds that execute on Java 7 to 24 can be analyzed. The analysis understands standard language features in Java 8 to 24; "preview" and "incubator" features are not supported. Source code using Java language versions older than Java 8 are analyzed as Java 8 code.
-    .. [6] ECJ is supported when the build invokes it via the Maven Compiler plugin or the Takari Lifecycle plugin.
-    .. [7] JSX and Flow code, YAML, JSON, HTML, and XML files may also be analyzed with JavaScript files.
-    .. [8] The extractor requires Python 3 to run. To analyze Python 2.7 you should install both versions of Python.
-    .. [9] Requires glibc 2.17.
-    .. [10] Support for the analysis of Swift requires macOS.
-    .. [11] TypeScript analysis is performed by running the JavaScript extractor with TypeScript enabled. This is the default.
