\ProvidesPackage{verbatimbox}
[2013/06/06 v3.1
Routines for placing verbatim text into boxes, useful in places where
the verbatim environment is inaccessible. Secondarily, for adding
vertical buffer around an object.]

% conditions of the LaTeX Project Public License, either version 1.3
% of this license or (at your option) any later version.
% The latest version of this license is in

%
% This work has the LPPL maintenance status `maintained'.
%
% The Current Maintainer of this work is Steven B. Segletes.
%
% verbatimbox.sty is based on boxedverbatim environment found
% in moreverb.sty.
%
% An enabling routine, \addvbuffer[]{} shares some functional
% similarities to \raisebox, but it is not the same.
%
% 2.01 -Added LPPL License info to package
% 3.0 -Added myverbbox environment
% -Corrected problem when no optional arguments are passed to
% verbbox environment
% -Added optional arguments to \addvbuffer
% -Fixed \verbfilebox so that it restored \verbatim@processline
% -Produced real documentation
% 3.01 -renamed \macro@name so as not to conflict with (I think) ltxdoc
% package
% 3.1 -Corrected default argument to \addvbuffer so that it wouldn't
% break. Also, gave better guidance in documentation to use
% of optional argument to \addvbuffer
% -Added verbnobox environment and \verbfilenobox macro
% -Improved documentation showing line-specific optional arguments
