我越来越喜欢 Donald Arseneau 的framed软件包。不过，我还想添加一些调整，但不知道该怎么做。
是否合并这两个环境framed和shaded，或修改一个并保留另一个，或者一起创建一个名为box或的第三个环境boxed尚不清楚，但我倾向于后者。
我喜欢shaded原样，因为它可以选择渗入边缘，或者通过添加星号，推动环境与边缘对齐。原样很棒。但它没有框架选项。环境也没有framed阴影选项，也没有像它那样超出边缘的选项shaded。
主要想法可能是创建一个全新的环境，称为boxed，它基本上是一个shaded渗入边缘的环境，但可以选择在其周围创建边框。然后是一个boxed*与边缘对齐的相应环境，如shaded*。
除此之外，对这些边框进行一些控制会非常有用：诸如topframe、leftframe、rightframe和bottomframe以及framecolor（和shadecolor）之类的选项将允许我创建一个与包自己的环境相比更有趣的框架framed。也许包参数\usepackage[booktabs]{boxed}会默认设置这些值以匹配表格的线条粗细booktabs（因此您不必每次想要使用该环境时都自己定义这些值）。
只是为了做到这一点真的topleft有趣的是，分别为、、topright和角设置半径，甚至可能在下面添加一个漂亮的阴影，可以完善该环境的外观和可控制性bottomleft。bottomright
（编辑：可能有一个选项可以手动重新定义框的宽度？默认情况下，要么出血到边距，要么与对齐。然后，如果您在非框中*提供，则框将采用该宽度加上填充的额外宽度；如果您在 ed 环境中执行相同操作，则框将采用的宽度，但不计算填充的额外宽度。）textwidth**textwidth
顺便说一句：如果您选择像 Donald Arseneau 那样编写具有版权的自定义标题，请考虑添加我和您自己，因为您编写了代码，而我提出了这个想法，也许还会提到 Donald Arseneau 提供的基础。
另外说明一下：如果所有这些选项都已在另一个包中提供，请提供软件包名称和带有所有这些选项都在使用中， 更何况解决默认边框粗细设置为与 booktabs 表的边框粗细相匹配的问题。

% framed.sty
% ~~~~~~~~~~
% Create framed, shaded, or differently highlighted regions that can
% break across pages. The environments defined are
% framed - ordinary frame box (\fbox) with edge at margin
% oframed - framed with open top/bottom at page breaks
% shaded - shaded background (\colorbox) bleeding into margin
% shaded* - shaded background (\colorbox) with edge at margin
% snugshade - shaded with tight fit around text (esp. in lists)
% snugshade* - like snugshade with shading edge at margin
% leftbar - thick vertical line in left margin
%
% to be used like
% \begin{framed}
% copious text
% \end{framed}
%
% But the more general purpose of this package is to facilitate the
% definition of new environments that take multi-line material,
% wrap it with some non-breakable formatting (some kind of box or
% decoration) and allow page breaks in the material. Such environments
% are defined to declare (or use) \FrameCommand for applying the boxy
% decoration, and \MakeFramed{settings} ... \endMakeFramed wrapped
% around the main text argument (environment body).
%
% The "framed" environment uses "\fbox", by default, as its "\FrameCommand"
% with the additional settings "\fboxrule=\FrameRule" and "\fboxsep=\FrameSep".
% You can change these lengths (using "\setlength") and you can change
% the definition of "\FrameCommand" to use much fancier boxes.
%
% In fact, the "shaded" environment just redefines \FrameCommand to be
% "\colorbox{shadecolor}" (and you have to define the color `"shadecolor"':
% "\definecolor{shadecolor}...").
%
% Although the intention is for other packages to define the varieties
% of decoration, a command "\OpenFbox" is defined for frames with open
% tops or bottoms, and used for the "oframed" environment. This facility
% is based on a more complex and capable command "\CustomFBox" which can
% be used for a wider range of frame styles. One such style of a title-bar
% frame with continuation marks is provided as an example. It is used by
% the "titled-frame" environment. To make use of "titled-frame" in your
% document, or the "\TitleBarFrame" command in your own environment
% definitions, you must define the colors TFFrameColor (for the frame)
% and a contrasting TFTitleColor (for the title text).
%
% A page break is allowed, and even encouraged, before the framed
% environment. If you want to attach some text (a box title) to the
% frame, then the text should be inserted by \FrameCommand so it cannot
% be separated from the body.
%
% The contents of the framed regions are restricted:
% Floats, footnotes, marginpars and head-line entries will be lost.
% (Some of these may be handled in a later version.)
% This package will not work with the page breaking of multicol.sty,
% or other systems that perform column-balancing.
%
% The MakeFramed environment does the work. Its `settings' argument
% should contain any adjustments to the text width (via a setting of
% "\hsize"). Here, the parameter "\width" gives the measured extra width
% added by the frame, so a common setting is "\advance\hsize-\width"
% which reduces the width of the text just enough that the outer edge
% of the frame aligns with the margins. The `settings' should also
% include a `restore' command -- "\@parboxrestore" or "\FrameRestore"
% or something similar; for instance, the snugshade environment uses
% settings to eliminate list indents and vertical space, but uses
% "\hspace" in "\FrameCommand" to reproduce the list margin ouside the
% shading.
%
% There are actually four variants of "\FrameCommand" to allow different
% formatting for each part of an environment broken over pages. Unbroken
% text is adorned by "\FrameCommand", whereas split text first uses
% "\FirstFrameCommand", possibly followed by "\MidFrameCommand", and
% finishing with "\LastFrameCommand". The default definitions for
% these three just invokes "\FrameCommand", so that all portions are
% framed the same way. See the oframe environment for use of distinct
% First/Mid/Last frames.
%
% Expert commands:
% \MakeFramed, \endMakeFramed: the "MakeFramed" environment
% \FrameCommand: command to draw the frame around its argument
% \FirstFrameCommand: the frame for the first part of a split environment
% \LastFrameCommand: for the last portion
% \MidFrameCommand: for any intermediate segments
% \FrameRestore: restore some text settings, but fewer than \@parboxrestore
% \FrameRule: length register; \fboxrule for default "framed".
% \FrameSep: length register; \fboxsep for default "framed".
% \FrameHeightAdjust: macro; height of frame above baseline at top of page
% \OuterFrameSep: vertical space before and after the framed env. Defaults to "\topsep"
%
% This is still a `pre-production' version because I can think of many
% features/improvements that should be made. Also, a detailed manual needs
% to be written. Nevertheless, starting with version 0.5 it should be bug-free.
%
% ToDo:
% Test more varieties of list
% Improve and correct documentation
% Propagation of \marks
% Handle footnotes (how??) floats (?) and marginpars.
% Stretchability modification.
% Make inner contents height/depth influence placement.
