A new package has been installed at tug.ctan.org and should soon make its way to your favorite mirror.
Thanks again for the package, Jim Hefferon Saint Michael's College

Name of contribution: xnewcommand Author's name: Josselin Noirel Location on CTAN: /macros/latex/contrib/xnewcommand Summary description: Allow to define protected or global macros by means of ewcommand License type: lppl
Announcement text: ---------------------------------------------------------------------- For most purposes, the features of ewcommand suffice. Nonetheless, ewcommand lacks some interesting features like the ability to make definition global or to use the protected prefix supplied by e-TEX. This--surprisingly small--package makes possible to pass an optional argument ewcommand so that is becomes possible to use the global and protected prefixes. ----------------------------------------------------------------------
