+% Conflict Resolver <noconflict.sty>
+% Resolves Macro Name Conflict among Packages
+% Copyright 2013 M. Zahid Hossain
+%
+% This package resolves macro name conflict among packages with concise 
+% approaches and user-friendly syntaxes.
+%
+% This program may be distributed and/or modified under the conditions 
+% of the LaTeX Project Public License, either version 1.2 of this 
+% license or (at your option) any later version.
+%
+% A macro name can be defined by many packages. In LaTeX, macro name need 
+% to be unique for a document and thus using the packages with same macro 
+% name causes conflict among them. In order to avoid macro name conflict 
+% this package defines several commands to save, restore and rename macros 
+% defined by other packages.
+%
+% PACKAGE COMMANDS
+% ================
+%
+% \prefix{<prefix added to the macro name>}
+% \save{<prefix added to the macro name>}
+%      {<comma separated list of macro name>}
+% \save*{<comma separated list of macro name>}
+% \restore{<prefix added to the macro name>}
+% \restore*
+% \reinstate{<prefix added to the macro name>}
+%           {<comma separated partial list of macro name>}
+% \rename{<old name>}{<new name>}
+%
+% USAGE EXAMPLE
+% =============
+%
+% If package A, B and C define three macro names X, Y and Z. To avoid macro 
+% name conflict:
+%
+% \usepackage{noconflict}
+% \usepackage{A}
+% \prefix{First} is optional
+% \save{X,Y,Z}
+%
+% \usepackage{B}
+% \save{Second}{X,Y,Z}
+% The above line can also be written as: \prefix{Second} and \save*{X,Y,Z}
+%
+% \usepackage{C}
+% \save{Third}{X,Y,Z}
+%
+% Now macro X, Y and Z of
+% Package A: \FirstX, \FirstY, \FirstZ
+% Package B: \SecondX, \SecondY, \SecondZ
+% Package C: \ThirdX, \ThirdY, \ThirdZ
+%
+% \restore{First}
+% Macros \FirstX, \FirstY and \FirstZ become \X, \Y and \Z
+% \restore{Second}
+% The above line can also be written as: \prefix{Second} and \restore*
+% The above line can also be written as: \reinstate{Second}{X,Y,Z}
+% Macros \SecondX, \SecondY and \SecondZ become \X, \Y and \Z
+% \restore{Third}
+% Macros \ThirdX, \ThirdY and \ThirdZ become \X, \Y and \Z
+% \rename{X}{CofX}
+% Macro \X becomes \CofX
