%% I thought that a replacement was needed and therefore created the pageslts package,

%% . Nevertheless, for compatibility with existing documents/packages as well as for
%% the low amount of resources needed by the lastpage package (no new counter!),
%% I updated this package.
%% Thanks go to Jeffrey P. Goldberg for allowing me to do this.

%% lastpage may work with earlier versions of LaTeX,
%% but this was not tested. Please consider updating
%% your LaTeX (and packages) to the most recent version
%% (if it is/they are not already the most recent version).

%% Allows for things like
%% Page \thepage{} of \pageref{LastPage}
%% to get
%% 'Page 7 of 9'.
%% For LaTeX 2.09 use lastpage209.sty.
%% For LaTeX 2e maybe consider upgrading to the pageslts package.
%% lastpage may work with earlier versions of LaTeX2e,
%% but this was not tested. Please consider updating your LaTeX
%% contribution to the most recent version (if it is not already
%% the most recent version).

%% The recent version of the endfloat package is v2.5d as of 2011/12/25.
%% The lastpage package is not fully compatible with version 2.0
%% (and earlier) of the endfloat package, because those versions
%% redefined the \enddocument command.
