% %% Inline-code environments

% % Shorter macro to use default behavior of \codevrb||
% \newcommand\term[1]{\codevrb#1}

% % Verb-like command for inserting inlined syntax-colored code as
% % assembly.
% %
% % Arguments:
% %  #1 - verbatim string
% %
% %  If the verbatim string you're coloring is a complete line of
% %  assembly, this command should correctly color it.  If the verbatim
% %  string is a portion of a line of assembly, however, then the GAS
% %  lexer will not parse it correctly.  In that case, use one of the
% %  special macros
% \newcommand\asmvrb[1]{\codevrb[gascb]#1}

% % Verb-like command for inserting inlined syntax-colored code as
% % a bash console command.
% %
% % Arguments:
% %  #1 - verbatim string
% %
% % If the verbatim string you're coloring is either a complete shell
% % command with the preceding "$" or ">" or the output from such a
% % shell command, this macro will color it correctly.  If the verbatim
% % string is not one these but instead, for example, simply a command
% % name, argument, or flag, then this command will not color it
% % correctly.
% \newcommand\shvrb[1]{\codevrb[console]#1}

% % Verb-like command for inserting inlined syntax-colored code as
% % cilk.
% %
% % Arguments:
% %  #1 - verbatim string
% \newcommand\cvrb[1]{\codevrb[cilk]#1}

% % Shortened form of \asmvrb command
% \newcommand\asm[1]{\asmvrb#1}

% % Shortened form of \shvrb command
% \newcommand\sh[1]{\shvrb#1}

% % Shortened form of \cvrb command
% \newcommand\cc[1]{\cvrb#1}
