+CENSOR
-The censor package allows a convenient redaction/censor
-capability to be employed, for those who need to protect
-restricted information, as well as for those who are
-forced to work in a more inefficient environment when
-dealing with restricted information.
+This package provides simple tools for creating redacted documents with
+blacked-out text. It's tools are useful both for creating documents in
+a restricted environment (for redacted release in an unrestricted
+environment) as well as in an unrestricted environment (for eventual
+transfer and completion in the restricted environment).
-Author: Steven Segletes
+As of V2.00, the ability to blackout larger blocks of text is available,
+up to a whole paragraph simply, and even across paragraph boundaries
+(with a small modification required to your text).
+
+V2.1 tries to minimize formatting discrepancies (i.e., text spacing)
+between the redacted and unredacted versions of the document.

+
+There are several caveats regarding the use of \verb|\blackout|. First,
+its argument cannot, without help, extend across paragraph boundaries.
+The help needed by \textsf{censor} is to insert the token \verb|\bpar|
+on your blank lines that would normally constitute paragraph boundaries,
+as shown in the example below:
+
+\verb|\blackout{|\\
+\verb|First paragraph to censor.|\\
+\verb| \bpar|\\
+\verb|Second paragraph to censor.}|\\
+
+\vspace{-0.7em}%
+will appear as
+
+\blackout{
+First paragraph to censor.
+ \bpar
+Second paragraph to censor.}
+
+Secondly, the argument cannot end on so-called ``glue,'' such as a space
+or a carriage return. The following examples are, thus, bad forms of
+the \verb|\blackout| command:
+
+\verb|\blackout{Ends in space. Bad form }|
+
+\verb|\blackout{Ends in carriage return. Bad form|\\
+\verb|}|
+
+Thirdly, periods are not censored (as of version 2.1). This is done
+because it is necessary to preserve the period-space combination that
+signifies end-of-sentence. In this way, {\LaTeX} can preserve spacing
+in the redacted version that is identical to the unredacted version.
+
+Fourthly, \verb|\blackout| does not work across environment boundaries,
+such as math or tabular mode. You can blackout text in the table, cell
+by cell; But you cannot blackout the whole tabular environment.
+
+Finally, the argument to \verb|\blackout| can employ tokens; However,
+the tokens are expanded into one large blackout, regardless of whether
+the expanded token contains spaces. Thus
+
+\verb|\blackout{\today}|
+
+becomes \blackout{\today}, in spite of the fact that \verb|\today|,
+given at the moment by \today, constains spaces.

\section{Miscellany}
Censoring may be dynamically turned on and off in a document with the
use of the \verb|\StopCensoring| and \verb|\RestartCensoring| commands.
-In addition to these two commands, the \verb|\censor| and \verb|\censor*|

+In addition to these two commands, the \verb|\censor|, \verb|\censor*|.
+and \verb|\blackout| commands constitute the totality of commands
+available in the \textsf{censor} package.
It is preferable not to apply \verb|\censor| to whitespace, or text
justification could be adversely affected. If one wished to censor a
multi-word phrase, such as ``Little Bo Peep,'' it is recommended to do
it as follows:\\
-\verb| \censor{Little} \censor{Bo} \censor{Peep}|\\
+\verb| \blackout{Little Bo Peep}|\\
If such a phrase is to be used repeatedly through a document,
it is most convenient to place it as a keyword identifier:\\
-\verb| \def\Name{\censor{Little} \censor{Bo} \censor{Peep}}|\\
+\verb| \def\Name{\blackout{Little Bo Peep}}|\\
such that subsequent reference is done indirectly:\\
-\verb| We examine the life of {\Name} in this report|\\
