+LaTeX Package : xfor
+
+Last Modified : 27 June 2009
+Version       : 1.0 (Initial Release)
+Author        : Nicola Talbot
+
+This package redefines \@for so that it is possible to
+prematurely terminate the loop.
+
+The package is supplied using the TeX Directory Structure (TDS).
+Files in texmf directory should go in the corresponding
+$LOCALTEXMF directories.
+
+*Remember to refresh TeX's database*
+
+The package and documentation source code is also supplied as a
+dtx and ins file located in texmf/source.
