Modules galore!

[ #1116 ]

So, my boss approved my CPAN uploads today. So, heading to a local CPAN mirror near you today are:

PPerl - the persistent perl interpreter that I talked about so much in my journal before. It basically turns any old perl script into a persistent daemon process. This is useful (for example) for things like Mail::Audit scripts that run for much less than their startup time. We're going to be using it here to run our spam and virus scanning scripts under (we process about 50 million emails a day).

XML::Generator::Win32OLETypeLib - This generates XML (via SAX) from the COM type database on your windows system. I talked about it way back in this journal's formative days.

File::Same - check which files in a multitude of directories are actually the same file (using MD5 sums). We use this here for our porn scanning guy (yes, it's a manual service right now :-) who filters images into different directories, and has to be sure he doesn't get duplicates. I couldn't find anything on CPAN that basically did just that. And it seemed fairly useful. It is slow though.

There's probably more to come. I'm scanning my hard drive now :-)
