It does of course work on Win2k and WinXP. I woud not recommend using
srvany.exe though.
It's much better to use either ActiveState's PerlSvc (pert of Perl
Dev. Kit) or Dave Roth's Win32::Daemon ( should be instalable via PPM
)
There's another thing ... if the processing of the files takes a lot
of time it might be better to use two threads. One that would watch
the directories, the other that would process the files. You do not
need a lot of synchronization in this, a single one-way pipe should
be enough.

P.S.: I made a service that translates our ASPs and web pages for
multilingual websites that does just this. One thread watches the
directories and tests the service status and sends commands like
"directory X changed", "reload initfile", "check for updated
translations" and "quit" to the worker thread. You might find handy
my Win32::BiggerPipe ( http://jenda.krynicky.cz/perl/BiggerPipe.pm )
in case the processing takes long and the changes happen too often.

There is a reason for living. There must be. I've seen it somewhere.
It's just that in the mess on my table ... and in my brain
I can't find it.
