Cool! 15 years of perl and I never used /e I got the regexp to convert the first file and discovered that sprintf is way more inconvenient than I remember. It doesn't return the string, it returns pass/fail. And it operates on char* ?
This may have been why I used boost::format. Anyone know of a c++ self contained function that takes a format string and returns the result string rather than using char*'s and returning the value in a char*? It's always something.
