+%    At the current point in time, basic support for PDF in
+%    backends is not part of \LaTeX{} core; it is provided by external
 %    packages. At some time in the future that work will be placed
 %    into the kernel but for now it is separate and has to be
 %    explicitly loaded in the document.
 %
-%    There is a command \cs{IfPDFManagementActiveTF} in that code
-%    which checks if the PDF management code is activated, which can
-%    be used by packages to execute different code branches depending
-%    on the state.
-%
-%    To make this also work properly if the external package is not
-%    loaded at all this command is already made available in the
-%    kernel (with a trivial definition) so that other packages can
-%    query the state in all circumstances.  Once the PDF management
-%    support moves to the kernel this definition here will vanish
-%    again or rather will be replaced by a real test.
+%    In that code there is a command \cs{IfPDFManagementActiveTF} 
+%    which can be used by packages in order to execute different 
+%    code depending on the whether this basic backend support is loaded.
 %
+%    To make this also work properly when this external package is not
+%    loaded at all, we here add this command already in the
+%    kernel (with a trivial definition); thus any package can
+%    query this loading state in all circumstances.  
+%    Once this basic PDF backend
+%    support gets moved to the kernel, this definition will vanish
+%    again from here or, rather, it will be replaced by a real test.

 %  \begin{macro}{\IfPDFManagementActiveTF}
-%    While the PDF management code is not loaded, the test will
-%    always return the false branch. Once this code is loaded, it
-%    is replaced by a real test (as then it is possible that the
-%    management code is activate or not activated).
+%    So long as the code for the basic backend support for PDF is not 
+%    loaded, the test that is implicit here will
+%    always return the false branch. 
+%    Once this code is loaded, this definition will get
+%    replaced by a real test (as it is then possible that the
+%    management code is either activated or not activated).
