quoth the cambridge upload daemon:
The following information was provided by the package's contributor.
Name of contribution: xfor Author's name: Nicola Talbot Location on CTAN: macros/latex/contrib/xfor Summary description: extends @for License type: lppl
Announcement text given by the package's contributor:
The xfor package redefines @for so that it is possible to prematurely terminate the loop before the end of the list is reached. A conditional is provided to afterwards test if the loop prematurely terminated, and the remainder of the list is stored in @forremainder.
thanks for the upload; i've installed it as suggested and made an entry in the catalogue.
Interested viewers may look at my first stab at a catalogue entry for the package at http://www.tex.ac.uk/tex-archive/help/Catalogue/entries/xfor.html or may browse the package itself at http://www.tex.ac.uk/tex-archive/macros/latex/contrib/xfor
