+BXenclose Package
+=================
+
+LaTeX: To enclose the document body with some pieces of code
+                                                            
+The package enables authors to designate in the preamble to make the
+document body enclosed with the given pieces of code. As is known,
+there are already various mechanisms provided by LaTeX kernel or
+packages that attach “hooks” at the beginning and end of documents.
+This package tries harder to win the race, that is, place the given
+code as close to the real document body as possible.
+
+### System requirement
+
+  * TeX format: LaTeX.
+  * TeX engine: Anything.
+  * Dependent packages: None.
+
+### Installation
+
+  - `*.sty` → $TEXMF/tex/latex/BXenclose
+
+### License
+
+This package is distributed under the MIT License.
+
+The bxenclose Package
+---------------------
+
+### Package Loading
+
+    \usepackage{bxenclose}
+
+No options are available.
+
+### Usage
+
+This package defines the following single command:
+
+    \enclosebodywith{<begin>}{<end>}
+
+This command makes the document body enclosed with `<begin>`  and
+`<end>`. That is, `<begin>` is executed immediately before the body
+text (probably after other “begin-document hooks” provided by LaTeX
+itself and other packages) and `<end>`  is executed immediately after
+the body text (probably before other “end-document hooks”).
+
+Note that both `<begin>` and `<end>` code are treated as part of the
+document body. In particular, `<begin>` code cannot contain any
+preamble-restricted commands (such as `\listfiles`).
+
+Revision History
+----------------
+
+  * Version 0.2  〈2016/04/01〉
+      - The first public version.

+% The insertion of \bxew@begin@body@hook is realized by appending
+% the token to \document macro. But of course there are dozens of
+% packages that do the same thing, and in order to "win the race"
+% and put \bxew@begin@body@hook immediately before the actual body
+% content, I need to postpone the patching to \document as late as
+% possible. Hence comes my tactics, where the patching will be done
+% in invocation of "\begin{document}", just before expanding the
+% \document macro.
